ある。In order to achieve the above object, the present invention provides a structure in which reinforcing lateral ribs are integrally provided on an inner surface of a resin bumper, and a harness is fixed along the lateral ribs by a clamp member. Is formed of a spring plate having an approximately U-shaped cross section having an elastic piece and a back surface, and the lateral edge of the lateral rib into which the clamp member is inserted is slightly wider than the width dimension of the clamp member and the tip side is tapered. A sloping inclined surface is provided, and a harness holding portion that is curled to the outside to hold and hold the harness is provided at the tip of one elastic piece of the clamp member, and the elastic piece of the clamp member is inserted through the inclined surface. By inserting into the horizontal rib, the flat part on the inner side of the inclined surface of the horizontal rib is crimped from above and below between the harness holding part and the tip of the other elastic piece, and both side edges of the clamp member are pressed.

向のずれも解消される。The harness is held in advance in the harness holding portion of the clamp member, and the clamp member is inserted horizontally with respect to the lateral rib. At this time, the lateral rib is formed with an inclined surface that is slightly wider than the clamp member, so that the inclined surface serves as a guide surface and the clamp member is pushed open and smoothly inserted. And when you insert the clamp member all the way,
The harness holding part and the elastic piece pass over the inclined surface and are crimped to the flat part of the lateral rib. Therefore, there is no fear that the clamp member will fall out of the lateral rib, and since both side edges of the clamp member are positioned by the inclined surfaces, the displacement of the clamp member in the width direction is also eliminated.
第1図〜第3図は本考案にかかるハーネス固定構造を
備えたリヤバンパ1の一例を示す。1 to 3 show an example of a rear bumper 1 having a harness fixing structure according to the present invention.
図において、樹脂製のリヤバンパ1の内面には車幅方

いる。In the figure, a lateral rib 2 is integrally formed in the vehicle width direction on the inner surface of a rear bumper 1 made of resin, and a license lamp 3 is fixed downward at the center of the lateral rib 2. Further, a backup lamp 4 is fixed to the rear end of the rear bumper 1 toward the rear side, and the wiring harness 5 of the backup lamp 4 has the license lamp 3 described above.
The wiring is provided along the upper surface of the lateral rib 2 together with the harness.
上記横リブ2は厚みのほぼ一定な平坦部2aを有してお
り、この平坦部2aの先端縁部上面には、第3図に示すよ
うに下方へ傾斜した一定幅Aの傾斜面6が間欠的に設け
られている。The lateral rib 2 has a flat portion 2a having a substantially constant thickness, and an inclined surface 6 having a constant width A inclined downward as shown in FIG. 3 is provided on the upper surface of the tip edge portion of the flat portion 2a. It is provided intermittently.
一方、クランプ部材7は略コ字形に折曲された金属板
バネよりなり、その幅寸法Bは傾斜面6の幅寸法Aより
やや小さい。クランプ部材7は一対の弾性片7a,7bと背

態におけるハーネス保持部8とガイド部9の最小間隔D
は、上記横リブ2の平坦部2aの厚みCより小さい。な
お、間隔D=0、つまり自由状態におけるハーネス保持
部8とガイド部9が接触してもよい。On the other hand, the clamp member 7 is made of a metal leaf spring bent in a substantially U shape, and its width dimension B is slightly smaller than the width dimension A of the inclined surface 6. The clamp member 7 has a pair of elastic pieces 7a, 7b and a back surface portion 7c, and one elastic piece of the clamp member 7 is provided.
A harness holding portion 8 curled outward is provided at the tip of 7a to hold and hold the harness 5. In addition, a guide portion 9 that is open outward is formed at the tip of the other elastic piece 7b of the clamp member. The minimum distance D between the harness holding portion 8 and the guide portion 9 in the free state
Is smaller than the thickness C of the flat portion 2a of the lateral rib 2. Note that the distance D = 0, that is, the harness holding portion 8 and the guide portion 9 in the free state may contact each other.
なお、クランプ部材7の先端側の保持部8またはガイ
ド部9と背面部7cとの距離Eは、傾斜面6の長さFより
長い。The distance E between the rear portion 7c and the holding portion 8 or the guide portion 9 on the tip side of the clamp member 7 is longer than the length F of the inclined surface 6.
次に、上記構成からなるハーネス固定構造の組付方法
を説明する。Next, a method of assembling the harness fixing structure having the above configuration will be described.
まず、予めクランプ部材7のハーネス保持部8の中に
ハーネス5を抱き込んで保持しておく。次に、ハーネス
5を保持したクランプ部材7を横リブ2の傾斜面6に対
して水平方向に差し込む。このとき、クランプ部材7の
ハーネス保持部8とガイド部9は互いに外向きに開いて
おり、しかも傾斜面6を設けた横リブ2の先端部は先細
となっているので、クランプ部材7は横リブ2にスムー
ズに差し込まれる。そして、クランプ部材7を奥まで差
し込むと、ハーネス保持部8とガイド部9が傾斜面6を
乗り越えて横リブ2の平坦部2aに圧着する。この圧着力
により、走行時の振動が加わってもクランプ部材7が横
リブ2から抜け落ちる心配がなくなり、しかもクランプ
部材7の両側縁が傾斜面6の両端面6aで係止されるの
で、クランプ部材7が幅方向に位置ずれを起こすことも
ない。したがって、ハーネス5を確実に固定できる。First, the harness 5 is held and held in advance in the harness holding portion 8 of the clamp member 7. Next, the clamp member 7 holding the harness 5 is horizontally inserted into the inclined surface 6 of the lateral rib 2. At this time, the harness holding portion 8 and the guide portion 9 of the clamp member 7 are open outwardly from each other, and the tip of the lateral rib 2 provided with the inclined surface 6 is tapered, so that the clamp member 7 is laterally moved. It is inserted into the rib 2 smoothly. Then, when the clamp member 7 is inserted all the way, the harness holding portion 8 and the guide portion 9 pass over the inclined surface 6 and are crimped to the flat portion 2a of the lateral rib 2. Due to this crimping force, there is no concern that the clamp member 7 will fall out of the lateral rib 2 even if vibration is applied during traveling, and both side edges of the clamp member 7 are locked by both end surfaces 6a of the inclined surface 6, so that the clamp member The position of 7 does not shift in the width direction. Therefore, the harness 5 can be securely fixed.
また、クランプ部材7を横リブ2に対して圧入する
際、クランプ部材7の弾性片7a,7bや背面部7cには曲げ
応力が作用するが、ハーネス5を保持しているハーネス
保持部8には応力が掛からないので、ハーネス5に無理
な圧着力が作用しない。そのため、ハーネス5の損傷や
断線といった不具合を防止できる。Further, when the clamp member 7 is press-fitted into the lateral rib 2, bending stress acts on the elastic pieces 7a, 7b and the back surface portion 7c of the clamp member 7, but the harness holding portion 8 holding the harness 5 does. Since no stress is applied to the harness 5, an unreasonable crimping force does not act on the harness 5. Therefore, it is possible to prevent problems such as damage and disconnection of the harness 5.
なお、クランプ部材は図示する形状のものに限らず、
その材質も金属板バネに代えて樹脂材料を用いてもよ
い。In addition, the clamp member is not limited to the illustrated shape,
A resin material may be used instead of the metal leaf spring.
また、本考案のハーネス固定構造はリヤバンパに限ら
ず、フロントバンパにも適用できる。Further, the harness fixing structure of the present invention is applicable not only to the rear bumper but also to the front bumper.
以上の説明で明らかなように、本考案によればバンパ
の横リブに傾斜面を形成するとともに、クランプ部材の
弾性片の先端に外向きにカール状となったハーネス保持
部を形成したので、横リブに対するクランプ部材の差込
みが容易になるとともに、クランプ部材の差込み作業が
一方向となるので、従来のように横リブに対しクランプ
部材を直角方向に差し込む場合に比べて作業性が向上す
る。As is apparent from the above description, according to the present invention, since the inclined surface is formed on the lateral rib of the bumper and the outwardly curled harness holding portion is formed at the tip of the elastic piece of the clamp member, Since the clamp member can be easily inserted into the lateral rib and the clamping member can be inserted in only one direction, workability is improved as compared with the conventional case where the clamp member is inserted into the lateral rib at a right angle.
また、傾斜面がクランプ部材の取付構造の目印となる
ので、ハーネス保持作業が行いやすく、しかも傾斜面の
両端面でクランプ部材の両側縁を係止しているので、ク
ランプ部材の横ずれを防止することもできる。Moreover, since the inclined surface serves as a mark for the mounting structure of the clamp member, the harness holding work is easy to perform, and since both side edges of the clamp member are locked by both end surfaces of the inclined surface, lateral displacement of the clamp member is prevented. You can also
さらに、上記傾斜面は横リブの突出方向、即ちリヤバ
ンパの型抜き方向に傾いているので、スライド型等の特
殊な金型を使用することなく、リヤバンパの成形と同時
に簡単に形成できる。Further, since the inclined surface is inclined in the protruding direction of the lateral ribs, that is, in the die-removing direction of the rear bumper, it can be easily formed simultaneously with the molding of the rear bumper without using a special die such as a slide die.
また、ハーネスを抱き込んで保持するハーネス保持部
は外側へカールしているので、クランプ部材を横リブに
対して圧入する際、クランプ部材のハーネス保持部には
応力が掛からない。そのため、ハーネスに無理な圧着が
作用せず、ハーネスの損傷や断線といった不具合を防止
できる。Further, since the harness holding portion that holds and holds the harness is curled outward, no stress is applied to the harness holding portion of the clamp member when the clamp member is pressed into the lateral rib. As a result, the harness is not forcedly pressed, and problems such as damage and disconnection of the harness can be prevented.
