Description

本発明は、フランジ付カラーナットを含む締結構造体に関する。   The present invention relates to a fastening structure including a flanged collar nut.

（ａ） テーパ形状のフランジ付カラーナットを含む締結構造体
従来、テーパ形状のフランジ付カラーナットを被締結物に挿入し、フランジ付カラーナットにボルトをねじ込んだ締結構造体が提案されている（例えば、特許文献１参照）。ボルトをねじ込む際にフランジ付カラーナットが回転することを防止するために、フランジ付カラーナットの軸部の外周面に接着剤が配置されていることが望ましい。
（ｂ） ストレート形状のフランジ付カラーナットを含む締結構造体
図４は、図示略のボルトがねじ込まれるストレート形状（円筒形状）のフランジ付カラーナット２を樹脂製部材３の取付け穴３ａに挿入した締結構造体を示している。ボルト締結する際にフランジ付カラーナット２が回転することを防止するために、フランジ付カラーナットの軸部２ａの外周面に接着剤６が配置されている。 (A) Fastening structure including tapered flanged color nut Conventionally, a fastening structure is proposed in which a tapered flanged color nut is inserted into an object to be fastened and a bolt is screwed into the flanged collar nut ( For example, see Patent Document 1). In order to prevent the flanged collar nut from rotating when the bolt is screwed in, it is desirable that an adhesive be disposed on the outer peripheral surface of the shaft portion of the flanged collar nut.
(B) Fastening structure including straight flanged collar nut FIG. 4 shows that a straight (cylindrical) flanged collar nut 2 into which a bolt (not shown) is screwed is inserted into the mounting hole 3a of the resin member 3. A fastening structure is shown. In order to prevent the flanged collar nut 2 from rotating during bolt fastening, an adhesive 6 is disposed on the outer peripheral surface of the shaft portion 2a of the flanged collar nut.

しかし、従来のフランジ付カラーナットを含む締結構造体にはつぎの問題点がある。
（ａ） テーパ形状のフランジ付カラーナットを含む締結構造体
フランジ付カラーナットの軸部の外周面に接着剤を配置するために軸部の外周面に接着剤を塗布してフランジ付カラーナットを被締結物に挿入する場合、軸部の外周面への接着剤の塗り方によっては、軸部の外周面全体に接着剤を配置できない場合がある（ムラができる）。フランジ付カラーナットの軸部の外周面全体に接着剤が配置されないと、安定した接着力を得ることができなくなってしまう。
（ｂ） ストレート形状のフランジ付カラーナットを含む締結構造体
図４に示すように、ストレート形状のフランジ付カラーナット２は、樹脂製部材３の取付け穴３ａに対して軸ズレを起こしやすい。軸ズレを起こすと、接着剤６のはみ出し、ムラが起きてしまう。
国際公開第２００２／０６５１９３号パンフレット However, the conventional fastening structure including the flanged collar nut has the following problems.
(A) In order to place the adhesive on the outer peripheral surface of the shaft portion of the collar nut with the fastening structure flange including the tapered collar nut with the flange, the adhesive is applied to the outer peripheral surface of the shaft portion, When inserting into the article to be fastened, depending on how the adhesive is applied to the outer peripheral surface of the shaft portion, the adhesive may not be disposed on the entire outer peripheral surface of the shaft portion (unevenness can occur). If the adhesive is not disposed on the entire outer peripheral surface of the shaft portion of the flanged collar nut, a stable adhesive force cannot be obtained.
(B) Fastening structure including straight flanged collar nut As shown in FIG. 4, the straight flanged collar nut 2 is liable to cause axial misalignment with respect to the mounting hole 3 a of the resin member 3. When the axial displacement occurs, the adhesive 6 protrudes and unevenness occurs.

（３） 前記溝の断面形状において、前記溝の、最奥部から前記フランジ付カラーナットの軸方向一端側の開口縁までの距離ａは、前記溝の、前記最奥部から前記フランジ付カラーナットの軸方向他端側の開口縁までの距離ｂの２倍よりも大とされている、（１）記載のフランジ付カラーナットを含む締結構造体。 The present invention for achieving the above object is as follows.
(1) A fastening structure including a flanged collar nut, wherein a flanged collar nut is inserted into a mounting hole of a resin member, and a fastened member is fastened and fixed to the resin member with a bolt.
The flanged collar nut has a shaft portion extending in the axial direction of the flanged collar nut and a flange portion provided at one end of the flanged collar nut in the axial direction. It has a tapered shape with a smaller diameter toward the other axial end of the collar nut with flange.
The inner peripheral surface of the mounting hole of the resin part is tapered so that the diameter decreases from one end in the thickness direction of the resin member to the other end in the thickness direction.
A fastening structure including a flanged collar nut, wherein a groove is formed on the outer peripheral surface of the shaft portion of the flanged collar nut, and an adhesive is disposed in the groove.
(2) In the cross-sectional shape of the groove, the distance a from the innermost part of the groove to the opening edge on one end side in the axial direction of the collar nut with flange is the distance a from the innermost part of the groove to the flanged collar.

(3) In the cross-sectional shape of the groove, the distance a from the innermost part of the groove to the opening edge on one end side in the axial direction of the flanged collar nut is the distance a from the innermost part of the groove to the flanged collar. A fastening structure including a flanged collar nut according to (1), which is greater than twice the distance b to the opening edge on the other axial end side of the nut.

上記（１）〜（３）のフランジ付カラーナットを含む締結構造体によれば、以下の効果を得ることができる。
フランジ付カラーナットの軸部の外周面がテーパ状とされており、樹脂製部材の取付け穴の内周面がテーパ状とされており、軸部の外周面に溝を形成するとともに溝内に接着剤を配置している。そのため、軸部の外周面の溝部およびその周囲に予め接着剤を塗布しておいたフランジ付カラーナットを樹脂製部材の取付け穴に挿入していくと、（ｉ）フランジ付カラーナットが取付け穴に挿入されるにつれて軸部の外周面と取付け穴の内周面との間隔が狭くなっていくため、フランジ付カラーナットが取付け穴に挿入されるにつれて接着剤は押し潰されて拡がっていく。また、（ｉｉ）フランジ付カラーナットで接着剤が樹脂製部材の厚み方向他端側まで（取付け穴の奥まで）引きずられる。したがって、軸部の外周面全体または略全体にわたって均一にまたは略均一に接着剤を配置できる。 According to the fastening structure including the flanged collar nuts (1) to (3), the following effects can be obtained.
The outer peripheral surface of the shaft portion of the collar nut with flange is tapered, the inner peripheral surface of the mounting hole of the resin member is tapered, and a groove is formed in the outer peripheral surface of the shaft portion and in the groove Adhesive is arranged. For this reason, when a flanged collar nut having an adhesive applied in advance around the groove on the outer peripheral surface of the shaft portion is inserted into the mounting hole of the resin member, (i) the flanged collar nut is attached to the mounting hole. Since the gap between the outer peripheral surface of the shaft portion and the inner peripheral surface of the mounting hole becomes narrower as the sleeve is inserted into the mounting hole, the adhesive is crushed and expanded as the flanged collar nut is inserted into the mounting hole. In addition, (ii) the adhesive is dragged to the other end in the thickness direction of the resin member (to the depth of the mounting hole) by the collar nut with flange. Therefore, the adhesive can be disposed uniformly or substantially uniformly over the entire outer peripheral surface or substantially the entire shaft portion.

上記（２）または（３）のフランジ付カラーナットを含む締結構造体によれば、以下の効果を得ることができる。
溝の断面形状において、溝の、最奥部からフランジ付カラーナットの軸方向一端側の開口縁までの距離ａが、溝の、最奥部からフランジ付カラーナットの軸方向他端側の開口縁までの距離ｂよりも大とされている。そのため、距離ａが距離ｂよりも小とされている場合に比べて、軸部の外周面の溝部およびその周囲に予め接着剤を塗布しておいたフランジ付カラーナットを樹脂製部材の取付け穴に挿入する際、接着剤は、フランジ付カラーナットの軸方向他端側よりも軸方向一端側に拡がりやすくなる（流れやすくなる）。 According to the fastening structure including the flanged collar nut (2) or (3), the following effects can be obtained.
In the cross-sectional shape of the groove, the distance a from the innermost part of the groove to the opening edge on one end side in the axial direction of the collar nut with flange is the opening on the other end side in the axial direction of the collar nut with flange from the innermost part of the groove. The distance b is larger than the distance b to the edge. Therefore, compared to the case where the distance a is smaller than the distance b, the flanged collar nut with the adhesive applied in advance to the groove portion on the outer peripheral surface of the shaft portion is attached to the mounting hole of the resin member. When inserted into the adhesive, the adhesive is more likely to spread (is more likely to flow) to one axial end than the other axial end of the flanged collar nut.

以下に、図１〜図３を参照して、本発明実施例のフランジ付カラーを含む締結構造体を説明する。   Below, with reference to FIGS. 1-3, the fastening structure containing the collar with a flange of this invention Example is demonstrated.

本発明実施例のフランジ付カラーを含む締結構造体１０は、図１に示すように、フランジ付カラーナット２０を樹脂製部材３０の取付け穴３１に挿入し、樹脂製部材３０に対して被締結部材４０をボルト５０にて締結固定する締結構造体である。締結構造体１０は、フランジ付カラーナット２０と、樹脂製部材３０と、金属製の被締結部材４０と、ボルト５０と、フランジ付カラーナット２０を樹脂製部材３０に接着固定する接着剤６０と、を有する。   As shown in FIG. 1, the fastening structure 10 including the flanged collar according to the embodiment of the present invention inserts the flanged collar nut 20 into the mounting hole 31 of the resin member 30 and is fastened to the resin member 30. This is a fastening structure that fastens and fixes the member 40 with bolts 50. The fastening structure 10 includes a flanged collar nut 20, a resin member 30, a metal fastening member 40, a bolt 50, and an adhesive 60 that bonds and fixes the flanged collar nut 20 to the resin member 30.

フランジ付カラーナット２０は、金属製である。フランジ付カラーナット２０は、接着剤６０を用いて樹脂製部材３０に接着固定される。フランジ付カラーナット２０は、フランジ付カラーナット２０の軸方向（以下、カラー軸方向という）に延びる軸部２１と、カラー軸方向一端部に設けられるフランジ部２２と、を備える。   The flanged collar nut 20 is made of metal. The flanged collar nut 20 is bonded and fixed to the resin member 30 using an adhesive 60. The flanged collar nut 20 includes a shaft portion 21 that extends in the axial direction of the flanged collar nut 20 (hereinafter referred to as the collar axis direction), and a flange portion 22 that is provided at one end in the collar axis direction.

軸部２１は、フランジ付カラー２０の軸方向でフランジ部２２が設けられていない部分である。軸部２１は、ボルト５０が挿入されるボルト挿入用穴２１ａを備える。ボルト挿入用穴２１ａは、フランジ付カラーナット２０をカラー軸方向に貫通する貫通孔であってもよく、袋穴であってもよい（図示例では袋穴である場合を示している）。軸部２１の内周面に、ボルト５０がねじ込まれる雌ネジ２１ｂが形成されている。   The shaft portion 21 is a portion where the flange portion 22 is not provided in the axial direction of the flanged collar 20. The shaft portion 21 includes a bolt insertion hole 21a into which the bolt 50 is inserted. The bolt insertion hole 21a may be a through-hole penetrating the flanged collar nut 20 in the collar axial direction, or may be a bag hole (in the illustrated example, the case is a bag hole). A female screw 21 b into which the bolt 50 is screwed is formed on the inner peripheral surface of the shaft portion 21.

軸部２１の外周面２１ｃは、カラー軸方向他端２０ｂに向かうにつれて小径となるテーパ状とされている。外周面２１ｃには、溝２３が少なくとも１つ形成されている（本発明図示例では、溝２３が１つのみ形成されている場合を示している）。   The outer peripheral surface 21c of the shaft portion 21 is tapered so as to become smaller in diameter toward the other end 20b in the collar axis direction. At least one groove 23 is formed on the outer peripheral surface 21c (in the illustrated example of the present invention, only one groove 23 is formed).

溝２３は、カラー軸方向と直交する面内で延びている。溝２３は、軸部２１の全周にわたって形成されている。溝２３は、軸部２１の、カラー軸方向他端２０ｂからカラー軸方向一端２０ａ側に所定距離隔てた位置に形成されている。溝２３の横断面形状は、Ｖ字（略Ｖ字を含む）形状であってもよく、Ｕ字（略Ｕ字を含む）形状であってもよく、その他の形状であってもよい。図３に示すように、溝２３の横断面形状において、溝２３の最奥部２３ａからカラー軸方向一端２０ａ側の開口縁２３ｂまでの距離ａは、溝２３の最奥部２３ａからカラー軸方向他端２０ｂ側の開口縁２３ｃまでの距離ｂの２倍よりも大とされている。溝２３の深さは、軸部２１の強度に影響がないかまたはあっても無視できる程度に、設定されている。   The groove 23 extends in a plane orthogonal to the collar axis direction. The groove 23 is formed over the entire circumference of the shaft portion 21. The groove 23 is formed at a position of the shaft portion 21 that is spaced a predetermined distance from the other end 20b in the color axis direction toward the one end 20a in the color axis direction. The cross-sectional shape of the groove 23 may be V-shaped (including substantially V-shaped), U-shaped (including substantially U-shaped), or other shapes. As shown in FIG. 3, in the cross-sectional shape of the groove 23, the distance a from the innermost portion 23a of the groove 23 to the opening edge 23b on the one end 20a side in the collar axis direction is the innermost portion 23a of the groove 23 in the color axis direction. The distance b is larger than twice the distance b to the opening edge 23c on the other end 20b side. The depth of the groove 23 is set to such an extent that the strength of the shaft portion 21 is not affected or can be ignored.

樹脂製部材３０は、たとえばＣＦＲＰなどのＦＲＰ（繊維強化樹脂）製である。樹脂製部材３０は、１枚構成であってもよく、複数枚を樹脂製部材３０の厚み方向（カラー軸方向と同方向）に重ねた複数枚構成であってもよい。なお、図示例では１枚構成である場合を示している。   The resin member 30 is made of, for example, FRP (fiber reinforced resin) such as CFRP. The resin member 30 may have a single-sheet configuration, or may have a multiple-sheet configuration in which a plurality of layers are stacked in the thickness direction of the resin member 30 (the same direction as the color axis direction). In the illustrated example, the case of a single sheet configuration is shown.

樹脂製部材３０は、軸部２１が挿入される（嵌め込まれる、圧入される）取付け穴３１を備える。樹脂製部材３０は、さらに、フランジ部２２を収容する図示略の座ぐり部を備えていてもよい。   The resin member 30 includes a mounting hole 31 into which the shaft portion 21 is inserted (inserted or press-fitted). The resin member 30 may further include a counterbore portion (not shown) that accommodates the flange portion 22.

取付け穴３１の内周面３１ａは、樹脂製部材３０の厚み方向一端３０ａから厚み方向他端３０ｂに向かうにつれて小径となるテーパ状とされている。取付け穴３１に、軸部２１が、カラー軸方向他端２０ｂを挿入側端にして厚み方向一端３０ａ側から挿入されている。   The inner peripheral surface 31a of the mounting hole 31 is tapered so that the diameter thereof becomes smaller as it goes from the one end 30a in the thickness direction of the resin member 30 to the other end 30b in the thickness direction. The shaft portion 21 is inserted into the attachment hole 31 from the thickness direction one end 30a side with the other end 20b in the collar axial direction being the insertion side end.

カラー軸方向他端２０ｂは樹脂製部材３０の厚み方向他端３０ｂと、カラー軸方向に同じかまたは略同じ位置にある。そのため、カラー軸方向他端２０ｂと被締結部材４０とを接触（面接触）させることができ、ボルト５０の軸力による樹脂製部材３０のクリープによる締結力抜けは生じない。   The other end 20b in the color axis direction is at the same or substantially the same position as the other end 30b in the thickness direction of the resin member 30 in the color axis direction. Therefore, the other end 20b in the collar axial direction and the fastened member 40 can be brought into contact (surface contact), and no fastening force is lost due to creep of the resin member 30 due to the axial force of the bolt 50.

被締結部材４０と樹脂製部材３０は、ワッシャ５１（またはボルト５０の頭部裏面）とフランジ部２２とにより、ボルト軸方向（カラー軸方向と同方向）に挟まれる。   The fastened member 40 and the resin member 30 are sandwiched between the washer 51 (or the back surface of the head of the bolt 50) and the flange portion 22 in the bolt axis direction (the same direction as the collar axis direction).

接着剤６０は、軸部２１の外周面２１ｃ（溝部２３を含む）と取付け穴３１の内周面３１ａとの間Ａと、フランジ部２２のうち軸部２１からカラー半径方向外側に延びている部分の裏面（下面）２２ａと樹脂製部材３０の厚み方向一端３０ａ（面）との間Ｂに、配置される。接着剤６０は、軸部２１の外周面２１ｃの溝部２３およびその周囲とフランジ部２２の裏面２２ａとに接着剤６０を塗布したフランジ付カラー２０を、樹脂製部材３０の取付け穴３１に挿入することで、間Ａ，Ｂに配置される。なお、図２に示すように、接着剤６０を軸部２１の外周面２１ｃの溝部２３およびその周囲のみに塗布した場合であっても、フランジ付カラー２０を取付け穴３１に挿入していくと、接着剤６０が軸部２１の外周面２１ｃと取付け穴３１の内周面３１ａとによって押し潰されて拡がり間Ａから間Ｂに流入するため、フランジ付カラー２０に接着剤６０を予め塗布しておく部位は、軸部２１の外周面２１ｃの溝部２３およびその周囲のみであってもよい。   The adhesive 60 extends between the outer peripheral surface 21c (including the groove portion 23) of the shaft portion 21 and the inner peripheral surface 31a of the mounting hole 31, and from the shaft portion 21 of the flange portion 22 to the outer side in the collar radial direction. It arrange | positions between B between the back surface (lower surface) 22a of a part and the thickness direction one end 30a (surface) of the resin-made members 30. FIG. The adhesive 60 inserts the flanged collar 20 in which the adhesive 60 is applied to the groove portion 23 of the outer peripheral surface 21 c of the shaft portion 21 and the periphery thereof and the back surface 22 a of the flange portion 22 into the mounting hole 31 of the resin member 30. Thus, they are arranged between A and B. As shown in FIG. 2, even when the adhesive 60 is applied only to the groove portion 23 of the outer peripheral surface 21 c of the shaft portion 21 and the periphery thereof, the flanged collar 20 is inserted into the mounting hole 31. Since the adhesive 60 is crushed by the outer peripheral surface 21c of the shaft portion 21 and the inner peripheral surface 31a of the mounting hole 31 and flows from the space A to the space B, the adhesive 60 is applied to the flanged collar 20 in advance. The part to keep may be only the groove part 23 of the outer peripheral surface 21c of the axial part 21, and its periphery.

ここで、フランジ付カラー２０を含む締結構造体１０の締結方法を説明する。   Here, a fastening method of the fastening structure 10 including the flanged collar 20 will be described.

フランジ付カラー２０を含む締結構造体１０の締結方法は、（ａ）軸部２１の外周面２１ｃの溝部２３およびその周囲のみに、または軸部２１の外周面２１ｃの溝部２３およびその周囲とフランジ部２２の裏面２２ｂとに接着剤６０を塗布する工程と、（ｂ）接着剤６０が塗布されたフランジ付カラー２０を、樹脂製部材３０の取付け穴３１に、カラー軸方向他端２０ｂが樹脂製部材３０の厚み方向他端３０ｂとカラー軸方向に同一または略同一になるまで挿入し、接着剤６０を間Ａ，Ｂに配置する工程と、（ｃ）接着剤６０が硬化した後に、被締結部材４０の一面４０ａがカラー軸方向他端２０ｂに接触するようにして被締結部材４０の他側（フランジ付カラーナット２０と反対側）から、ボルト５０を、被締結部材４０のボルト挿通穴４１を挿通させて雌ネジ２１ｂにねじ込む工程と、を有する。   The fastening structure 10 including the flanged collar 20 includes: (a) the groove portion 23 of the outer peripheral surface 21c of the shaft portion 21 and its periphery only, or the groove portion 23 of the outer peripheral surface 21c of the shaft portion 21 and its periphery and the flange. A step of applying the adhesive 60 to the back surface 22b of the portion 22, and (b) the flanged collar 20 to which the adhesive 60 has been applied, the mounting hole 31 of the resin member 30, and the other end 20b in the color axial direction. Inserting the adhesive member 60 between the other end 30b in the thickness direction of the manufactured member 30 in the collar axis direction until it is the same or substantially the same, and disposing the adhesive 60 in the space A, B; (c) after the adhesive 60 is cured, The bolt 50 is inserted into the bolted hole of the fastened member 40 from the other side of the fastened member 40 (the side opposite to the flanged collar nut 20) so that one surface 40a of the fastening member 40 contacts the other end 20b in the collar axial direction. 4 It was inserted and a step of screwing the female screw 21b with.

つぎに、本発明実施例の作用を説明する。   Next, the operation of the embodiment of the present invention will be described.

本発明実施例では、軸部２１がテーパ状の外周面２１ｃを備えており、外周面２１ｃに溝２３を形成するとともに溝２３内に接着剤６０を配置している。そのため、軸部２１の外周面２１ｃの溝部２３およびその周囲に予め接着剤６０を塗布しておいたフランジ付カラーナット２０を樹脂製部材３０の取付け穴３１に挿入していくと、（ｉ）フランジ付カラーナット２０が取付け穴３１に挿入されるにつれて軸部２１の外周面２１ｃと取付け穴３１の内周面３１ａとの間隔が狭くなっていくため、フランジ付カラーナット２０が取付け穴３１に挿入されるにつれて接着剤６０は押し潰されて拡がっていく。また、（ｉｉ）フランジ付カラーナット２０で接着剤６０が樹脂製部材３０の厚み方向他端３０ｂ側まで（取付け穴３１の奥まで）引きずられる。したがって、軸部２１の外周面２１ｃの全体または略全体にわたって均一に（ムラなく）接着剤６０を配置でき、安定した接着力を得ることができる。   In the embodiment of the present invention, the shaft portion 21 is provided with a tapered outer peripheral surface 21 c, the groove 23 is formed in the outer peripheral surface 21 c, and the adhesive 60 is disposed in the groove 23. Therefore, when the flanged collar nut 20 in which the adhesive 60 is applied in advance to the groove portion 23 of the outer peripheral surface 21c of the shaft portion 21 and the periphery thereof is inserted into the mounting hole 31 of the resin member 30, (i) As the flanged collar nut 20 is inserted into the mounting hole 31, the distance between the outer peripheral surface 21 c of the shaft portion 21 and the inner peripheral surface 31 a of the mounting hole 31 becomes narrower. As it is inserted, the adhesive 60 is crushed and spreads. Further, (ii) the adhesive 60 is dragged by the flanged collar nut 20 to the other end 30b in the thickness direction of the resin member 30 (to the back of the mounting hole 31). Therefore, the adhesive 60 can be disposed uniformly (evenly) over the entire or substantially entire outer peripheral surface 21c of the shaft portion 21, and a stable adhesive force can be obtained.

溝２３の横断面形状において、溝２３の最奥部２３ａからカラー軸方向一端２０ａ側の開口縁２３ｂまでの距離ａが、溝２３の最奥部２３ａからカラー軸方向他端２０ｂ側の開口縁２３ｃまでの距離ｂの２倍よりも大とされている。そのため、距離ａが距離ｂよりも小とされている場合に比べて、軸部２１の外周面２１ｃの溝部２３およびその周囲に予め接着剤６０を塗布しておいたフランジ付カラーナット２０を樹脂製部材３０の取付け穴３１に挿入する際、接着剤６０が、カラー軸方向他端２０ｂ側よりもカラー軸方向一端２０ａ側に拡がりやすくなる（流れやすくなる）。   In the cross-sectional shape of the groove 23, the distance a from the innermost portion 23 a of the groove 23 to the opening edge 23 b on the one end 20 a side in the collar axis direction is the opening edge on the other end 20 b side in the collar axial direction from the innermost portion 23 a of the groove 23. The distance b is greater than twice the distance b up to 23c. Therefore, compared with the case where the distance a is smaller than the distance b, the flanged collar nut 20 in which the adhesive 60 is applied in advance to the groove portion 23 of the outer peripheral surface 21c of the shaft portion 21 and the periphery thereof is made of resin. When the adhesive 60 is inserted into the attachment hole 31 of the member 30, the adhesive 60 is more likely to spread toward the one end 20 a side of the collar axis than the other end 20 b of the collar axis direction (is easy to flow).

溝２３が、軸部２１の、カラー軸方向他端２０ｂからカラー軸方向一端２０ａ側に所定距離隔てた位置に形成されているため、軸部２１の外周面２１ｃと取付け穴３１の内周面３１とで押し潰された接着剤６０が、間Ａから被締結部材４０側に流出する（はみ出す）ことを防止できる。   Since the groove 23 is formed at a position that is a predetermined distance from the other end 20b of the collar axis direction toward the one end 20a of the collar axis direction, the outer peripheral surface 21c of the shaft part 21 and the inner peripheral surface of the mounting hole 31 are formed. It is possible to prevent the adhesive 60 crushed by 31 from flowing out from the space A to the fastened member 40 side.

軸部２１の外周面２１ｃと取付け穴３１の内周面３１ａがテーパ状とされているため、両面２１ｃ、３１ａがテーパ状とされていない場合に比べて（両面２１ｃ、３１ａがストレート状とされている場合に比べて）、フランジ付カラーナット２０を挿入するとき、入口が広い。そのため、軸部２１の外周面２１ｃの溝部２３およびその周囲に予め接着剤６０を塗布しておいたフランジ付カラーナット２０を樹脂製部材３０の取付け穴３１に挿入する際に、接着剤６０が樹脂製部材３０の取付け穴３１の入口（厚み方向一端３０ａ）で掻き落とされてしまう（削り落とされてしまう）ことを防止できる。その結果、軸部２１の外周面２１ｃの溝部２３およびその周囲に接着剤６０を予め塗布しておいたフランジ付カラーナット２０を樹脂製部材３０の取付け穴３１に挿入する際に、軸部２１の外周面２１ｃの溝部２３およびその周囲に塗布した接着剤６０の全部を取付け穴３１内に入れることができる。   Since the outer peripheral surface 21c of the shaft portion 21 and the inner peripheral surface 31a of the mounting hole 31 are tapered, both surfaces 21c and 31a are straightened (both surfaces 21c and 31a are straight). The inlet is wide when the flanged collar nut 20 is inserted. Therefore, when the flanged collar nut 20 in which the adhesive agent 60 has been applied in advance around the groove portion 23 of the outer peripheral surface 21c of the shaft portion 21 is inserted into the mounting hole 31 of the resin member 30, the adhesive agent 60 is It is possible to prevent scraping off (scraping off) at the entrance (one end 30a in the thickness direction) of the mounting hole 31 of the resin member 30. As a result, when the flanged collar nut 20 in which the adhesive 23 is applied in advance to the groove 23 of the outer peripheral surface 21c of the shaft 21 and the periphery thereof is inserted into the mounting hole 31 of the resin member 30, the shaft 21 All of the groove portion 23 of the outer peripheral surface 21c and the adhesive 60 applied to the periphery thereof can be put into the mounting hole 31.

軸部２１の外周面２１ｃと取付け穴３１の内周面３１ａがテーパ状とされているため、フランジ付カラーナット２０挿入時は入口が広くて入れやすく、挿入するにつれて次第にすぼんでくるので、フランジ付カラーナット２０が樹脂製部材３０の取付け穴３１に対してセンタリングされ（軸ズレすることなく）、フランジ付カラーナット２０を取付け穴３１に対して正確に位置決めできる。また、フランジ付カラーナット２０を樹脂製部材３０の取付け穴３１に挿入する際に、自動的にセンタリングされるため、作業性も良好である。   Since the outer peripheral surface 21c of the shaft portion 21 and the inner peripheral surface 31a of the mounting hole 31 are tapered, when the flanged collar nut 20 is inserted, the inlet is wide and easy to enter. The collar nut 20 with the center is centered with respect to the mounting hole 31 of the resin member 30 (without axial displacement), and the flanged collar nut 20 can be accurately positioned with respect to the mounting hole 31. Further, since the collar nut with flange 20 is automatically centered when inserted into the mounting hole 31 of the resin member 30, workability is also good.
