That is, according to the first rib, in the process of joining the first member and the second member, the fact that the engaging projection inserted from the inlet of the engaging groove has reached the back end of the vertical groove portion is related to the rib. This can be confirmed by the click feeling generated by the interference of the mating protrusion, and the engaging protrusion can be smoothly guided to the lateral groove portion by relatively rotating the cylindrical rod and the circular hole at the same position. Therefore, the first rib can clarify the position where the first member and the second member can be rotated relative to each other. In addition, since the engagement protrusion receives a resistance force in the return direction at the position due to the presence of the rib, the movement of the engagement protrusion inadvertently can be stopped.
Further, according to the second rib, in the process of releasing the coupling between the first member and the second member, the engagement protrusion completely passes through the lateral groove portion in accordance with the relative rotation operation of the engagement protrusion and the engagement groove. Then, it can be confirmed by the click feeling generated by the interference between the ribs and the engaging projections that the longitudinal end of the vertical groove has been reached. Then, the engagement protrusion can be extracted from the engagement groove by moving the cylindrical rod and the circular hole in the extraction direction at the same position. Therefore, the position where the relative movement operation in the axial direction between the first member and the second member can be clarified by the second rib. In addition, since the engagement protrusion receives a resistance force in the return direction at the position due to the presence of the rib, the movement of the engagement protrusion inadvertently can be stopped.
Further, according to the third rib, in the process of coupling the first member and the second member, the engagement protrusion guided to the lateral groove portion reaches the back end of the lateral groove portion, and the coupled state is completed. This can be confirmed by the click feeling generated by the interference between the rib and the engaging protrusion. In addition, since the engagement protrusion can be fastened at that position, it is possible to prevent rotation and prevention of disconnection.
According to the member fixing clip having the configuration (3) above, a plurality of sets of engagement protrusions and engagement grooves are provided at intervals in the circumferential direction, so that the first member and the second member are coupled in a balanced manner. Can be kept.
According to the member fixing clip having the configuration of the above (4), the relative rotation operation between the first member and the second member can be facilitated by the presence of the knob.
According to the member fixing clip having the configuration of (5) above, by confirming the mark, the first member and the second member are in an appropriate coupled state (locked state) or in an uncoupled state (unlocked state). You can easily see if there is.
According to the member fixing clip having the configuration (6), the first member and the second member are tightly coupled by sliding the engagement protrusion to the end of the engagement groove (the deep end of the lateral groove). Can do.
According to the member fixing clip having the configuration of (7) above, the base plate engaged with the back side of the vehicle body panel and the front side are inserted by inserting the base plate of the pedestal into the mounting hole of the vehicle body panel and rotating approximately 90 degrees. The vehicle body panel can be sandwiched between the pressing plate portion that is in pressure contact with the surface of the plate, and the pedestal can be fixed to the vehicle body panel.
Further, at the same time, the binding band and the pedestal attached in advance to the wire harness can be coupled by fitting the cylindrical rod and the circular hole. Therefore, when it is necessary to remove the wire harness, the pedestal can be detached from the vehicle body panel by simply rotating the pedestal approximately 90 degrees in the opposite direction and pulling the wire harness upward. The binding band attached to the wire harness can be detached from the base.

  According to the present invention, since the engagement groove into which the engagement protrusion fits is provided in a bowl-shaped path composed of the vertical groove portion and the horizontal groove portion, just by inserting the engagement protrusion into the engagement groove and turning it, The first member and the second member can be connected, and the coupling between the first member and the second member can be released simply by turning in the opposite direction and removing. By separating the first member and the second member, an attachment target member such as a wire harness can be easily detached from a fixation target member such as a vehicle body panel. In addition, the number of parts is the minimum number that can be disassembled, and once the first member and the second member are joined, it becomes difficult to come off, so there is no risk of parts falling off or parts missing.

Two engaging projections 15 are provided at positions facing each other.

  The base plate 14 is of a size that can be inserted into a rectangular mounting hole 2 formed in the vehicle body panel 1 from the front side to the back side of the vehicle body panel 1, and is inserted into the back side of the vehicle body panel 1. As shown in FIG. 6, it is formed to have a size that engages with the back side of the vehicle body panel 1 by being rotated approximately 90 degrees. That is, the length of the long side of the rectangular base plate 14 having the short side and the long side is set to be shorter than the length of the long side of the rectangular mounting hole 2 but longer than the length of the short side. Further, the skirt-shaped pressing plate portion 13 presses and contacts the front side surface of the vehicle body panel 1 when the base plate 14 is engaged with the back side of the vehicle body panel 1, so that the vehicle body panel 1 is brought together with the base plate 14. Thus, the pedestal 10 itself is provided so as to be fixed to the vehicle body panel 1.

  The binding band 20 is a rectangular box-shaped base portion 21, a band portion 28 whose base end is coupled to the side surface of the base portion 21, and a lower surface of the base portion 21, and is fitted into the circular hole 12 of the base 10. And a cylindrical rod 22. The base portion 20 is provided with an insertion hole 29 penetrating from one side surface to the other side surface of the base portion 20, and the distal end side of a band 28 rolled into a loop shape to bind the wire harness to the insertion hole 29. By passing the band 28, the band 28 is locked at an arbitrary position by a locking means (not shown) inside the insertion hole 29.

  When the cylindrical rod 22 is inserted into the circular hole 12 of the base 10, the engagement protrusion 15 on the circular hole 12 side is slidably fitted on the outer peripheral surface of the cylindrical rod 22 that slides with the inner peripheral surface of the circular hole 12. A full engagement groove 30 is provided. Similar to the engagement protrusion 15, two engagement grooves 30 are provided at positions facing each other by 180 degrees.

  Each engagement groove 30 includes a vertical groove portion 23 extending from the inlet opening at the tip of the cylindrical rod 22 along the axial direction of the cylindrical rod 22, and a horizontal groove portion 24 extending from the back end of the vertical groove portion 23 in the circumferential direction of the cylindrical rod 22. It is formed in a bowl-shaped path when viewed from the front. In this case, as shown in FIG. 2, the lateral groove portion 24 deepens the fitting between the cylindrical rod 22 and the circular hole 12 as the engagement protrusion 15 slides toward the inner end of the lateral groove portion 24. It is formed in an oblique cam groove shape. Further, the base 10 and the binding band 20 abut each other when the engaging projection 15 reaches the back end of the lateral groove portion 24, and abut against each other so that the engagement groove 30 and the engaging projection 15 are fitted in the axial direction. There is an abutment that gives power. Although not shown in the figure, the abutting surface in this case corresponds to the inner bottom surface of the circular hole 12 and the tip surface (lower end surface) of the cylindrical rod 22.

  In this embodiment, the relative rotation angle between the cylindrical rod 22 and the circular hole 12 required for engaging the engagement protrusion 15 and the engagement groove 30 and releasing the engagement is set to approximately 90 degrees. Has been. The relative rotation angle is the same as the rotation angle (approximately 90 degrees) necessary for engaging the base plate 14 of the base 10 with the back side of the vehicle body panel 1 and releasing the engagement.

  In addition, the cylindrical rod 22 and the circular hole 12 are relatively moved on the inner bottom surface of the engagement groove 30 to confirm the position of the movement operation when the engagement protrusion 15 slides in the engagement groove 30. Are provided with first to third three ribs (small projections) 25, 26 and 27 for providing a click feeling and a resistance force to stop the inadvertent movement of the engaging projection 15.

  As shown in detail in FIGS. 2 (a) and 2 (b), the first rib 25 has an engagement protrusion 15 inserted from the entrance in front of the rear end of the vertical groove portion 23 at the rear end of the vertical groove portion 23. It is provided as a reminder of the arrival. Further, the second rib 26 is immediately after the communication port connected from the back end of the vertical groove portion 23 to the horizontal groove portion 24, and when the engagement projection 15 returns from the back end of the horizontal groove portion 24 toward the communication port, It is provided to notify that the engaging protrusion 15 has completely passed through the lateral groove portion 24 and has reached the far end of the vertical groove portion 23. The third rib 27 is provided in front of the back end of the lateral groove portion 24 to notify that the engagement projection 15 has reached the back end of the lateral groove portion 24, and the engagement projection 15 is provided at the back end. It is provided as a locking means for retaining.

  As shown in FIG. 4, the knob 16 is provided to hang a finger or the like when the pedestal 10 is rotated in the directions of arrows C and D, and the position of the knob 16 is determined by the binding band 20. Depending on where the base portion 21 is located, the upper surface of the base portion 21 has “ON” and “OFF” display portions (marks) 21A so that the positional relationship between the engaging protrusions 15 and the engaging grooves 30 can be seen at a glance. Is provided. Here, when the engagement protrusion 15 is located at the back end of the lateral groove portion 24, that is, when the base 10 and the binding band 20 are completely coupled, it is indicated that the knob portion 16 comes to the “ON” position. Is attached. In addition, when the engagement protrusion 15 is located on the longitudinal groove 23, that is, when the base 10 and the binding band 20 are separated from each other, an indication is given so that the knob portion 16 comes to the “OFF” position. Yes.

Next, the operation will be described.
First, the case where this band clip is assembled alone will be described. In this case, as shown by the arrow A in FIGS. 1 and 5, the cylindrical rod 22 of the binding band 20 is placed on the pedestal 10 while aligning the position of the engagement protrusion 15 and the inlet of the vertical groove 23 of the engagement groove 30. Is inserted into the circular hole 12.

  At the time of insertion, the “OFF” position of the display unit 21 of the base 10 is matched with the position of the knob 16. Then, even if the position of the engagement groove 30 and the position of the engagement protrusion 15 are not directly seen, the positions of the engagement groove 30 and the engagement protrusion 15 can be aligned only by looking at the knob portion 16 and the display portion 21A from above. Therefore, the assembling work can be easily performed.

  When the cylindrical rod 22 is inserted into the circular hole 12 of the pedestal 10, the engagement protrusion 15 slides along the vertical groove portion 23. If it inserts to the position where the engagement protrusion 15 reaches | attains the back end of the vertical groove part 23, the base 10 will be rotated as shown by the arrow C of FIG. If it does so, the engagement protrusion 15 will move to the horizontal groove part 24 from the vertical groove part 23, and will stop when it reaches | attains the back end of the horizontal groove part 24. FIG. At this stage, the cylindrical rod 22 is engaged so as not to come out of the circular hole 12, whereby the base 10 and the binding band 20 are coupled. At this time, since the knob portion 16 is positioned at the “ON” position of the display portion 21 </ b> A, it is possible to know that the pedestal 10 and the binding band 20 are in a coupled state by visually confirming this.

  In this case, when the engaging protrusion 15 slides to the far end of the lateral groove portion 24, it moves obliquely with respect to the cylindrical rod 22, so that the tip surface of the cylindrical rod 22 comes into contact with the inner bottom portion of the circular hole 12. By abutting, an axial tightening force is applied to the engagement between the engagement groove 30 and the engagement protrusion 15, and as a result, the pedestal 10 and the binding band 20 are tightly coupled without looseness.

  Further, since the first rib 25 is provided on the inner surface of the engagement groove 30, the engagement protrusion 15 inserted from the entrance of the engagement groove 30 is connected to the vertical groove portion 23 in the process of coupling the base 10 and the binding band 20. The arrival at the far end can be confirmed by a click feeling generated by the interference between the first rib 25 and the engaging protrusion 15. Therefore, the engaging projection 15 can be smoothly guided to the lateral groove portion 24 by relatively rotating the cylindrical rod 22 and the circular hole 12 at the same position. Therefore, the first rib 25 can clarify the position where the base 10 and the binding band 20 can be rotated relative to each other. Moreover, since the engagement protrusion 15 receives a resistance force in the return direction at the position due to the presence of the first rib 25, the movement (return) of the engagement protrusion 15 inadvertently can be stopped.

  Further, due to the presence of the third rib 27, in the process of coupling the base 10 and the binding band 20, the engagement protrusion 15 guided to the lateral groove portion 24 reaches the back end of the lateral groove portion 24, and the coupled state is completed. This can be confirmed by the click feeling generated by the interference between the third rib 27 and the engaging protrusion 15. Moreover, since the engagement protrusion 15 can be fastened at that position, it is possible to prevent rotation and prevention.

  On the other hand, when uncoupling the two, the base 10 is rotated in the direction of arrow D in FIG. Then, the engagement protrusion 15 moves from the lateral groove portion 24 to the inner end of the vertical groove portion 23, and at that stage, a force in the pulling direction is applied to the cylindrical rod 22 and the circular hole 12, whereby the arrow E in FIG. Thus, the cylindrical rod 22 can be pulled out from the circular hole 12, and the base 10 and the binding band 20 can be separated.

  Also in this case, since the second rib 26 is provided on the inner surface of the engagement groove 30, in the process of releasing the coupling between the base 10 and the binding band 20, the relative rotation operation of the engagement protrusion 15 and the engagement groove 30 is performed. It can be confirmed by the click feeling generated by the interference between the second rib 26 and the engagement protrusion 15 that the engagement protrusion 15 has completely passed through the lateral groove portion 24 and has reached the back end of the vertical groove portion 23. The engaging protrusion 15 can be extracted from the engaging groove 30 by moving the cylindrical rod 22 and the circular hole 12 in the extracting direction at the same position. Therefore, the position where the relative movement operation of the base 10 and the binding band 20 in the axial direction can be clarified by the second rib 26. In addition, since the engagement protrusion 15 receives a resistance force in the return direction at the position due to the presence of the second rib 26, the movement of the engagement protrusion 15 inadvertently can be stopped.

  As described above, the engaging groove 30 into which the engaging protrusion 15 is fitted is formed by the saddle-shaped path composed of the longitudinal groove portion 23 and the lateral groove portion 24. Therefore, the engaging protrusion 15 is inserted into the engaging groove 30. The pedestal 10 and the binding band 20 can be coupled simply by turning and the coupling between the pedestal 10 and the binding band 20 can be released simply by rotating in the opposite direction.

  That is, until the engagement protrusion 15 reaches the back end of the lateral groove portion 24 from the vertical groove portion 23 of the engagement groove 30 by the relative movement (axial insertion operation and rotation operation) of the cylindrical rod 22 and the circular hole 12. By sliding, the pedestal 10 and the binding band 20 can be coupled, and the engaging protrusion 15 is pulled out of the engaging groove 30 by the reverse movement (the rotating operation in the opposite direction and the pulling operation in the axial direction). Thus, the base 10 and the binding band 20 can be separated.

  Further, since the three ribs 25 to 27 are provided on the inner surface of the engagement groove 30 as described above, the position of the engagement protrusion 15 on the engagement groove 30 is confirmed, and the engagement groove 30 is not prepared. Therefore, it is possible to prevent the engagement protrusions 15 from moving and to facilitate the assembly and disassembly operations.
