The length is such that it is located closer to the bumper molding 12 than A. In one embodiment of the present application, a portion of the exterior component side clip protrudes from the back surface of the bumper molding 12, but the point is that it is sufficient that it does not protrude from the exterior component consisting of the bumper molding and the bumper cover. Further, the held portion 30 is attached to the claw portions 22A, 2
Since the elongated hole 40 is formed in the width direction of the body side clip 2B, it absorbs the displacement of the tuft pin screw 42 inserted from the leg 16 side of the body side clip 24 through the flange 18, and is easily screwed together. I'm starting to get it. Next, the process of attaching the bumper molding 12 using the fastener of the above embodiment will be explained. First, the legs 16 of the body side clip 24 are fitted into the opening 14 of the body 10. At this time, the diameter of the protruding part 16A of the leg part 16 is elastically reduced, and the protruding part 16A of the leg part 16 is inserted and pushed into the opening 14. Next, the body side clip 24 is rotated 45 degrees around the axis to fit the fitting portion 16B into the opening 14. In this state, the protrusion 16A elastically restores itself outward, so that the body side clip 24 is fixed in a state where the body 10 is sandwiched between the protrusion 16A and the flange 18. As shown in FIG. 3, the exterior component side clip 32 is attached in advance by being inserted into the opening 38 of the core bar 36 before the core bar 36 is inserted into the bumper molding 12. The core metal 36 to which the required number of exterior component side clips 32 are attached is slid inside the bumper molding 12 to accommodate the exterior component side clips 32. Next, the bumper mold 1 is attached to the bumper cover 26.
2 overlapped, align it with the body side clip 24 already attached to the opening 14 of the body 10, and attach the exterior parts side clip 32 together with the bumper molding 12 and the bumper cover 26 to the claw part of the body side clip 24. Push it between 22A and 22B. When the exterior component side clip 32 is aligned and pushed into the body side clip 24 together with the bumper molding 12 and the bumper cover 26, the held part 3
0 is the tapered surface 23 of the claw portions 22A, 22B.
These inner surfaces 21A, 21 along A, 23B
Get in between B. At this time, the claw parts 22A, 22B are narrower than the held part 30, and the inner tips of the claw parts 22A, 22B are tapered surfaces 23A, 23B that expand outward, so that the outer parts side Even if the body-side clip 24 is slightly misaligned with respect to the clip 32, the held portion 30 is easily pushed between the claw portions 22A and 22B. The held part 30 pushes apart the claw parts 22A, 22B and enters between the pair of holding pieces 20A, 20B, and when reaching the end of the stroke in the direction of the body 10, the claw parts 22A, 22B push the held part 30 apart. engages with the front end surface of. Therefore, the held portion 30 is aligned with the claw portion 2 in the axial direction.
It is held between 2A, 22B and the flange 18, and between the holding pieces 20A, 20B in the direction perpendicular thereto. Therefore, the bumper molding 12 is temporarily fixed to the body side clip 24 via the exterior component side clip 32. Next, insert the tuft pin screw 42 from the back side of the body 10 through the leg portion 16 and the flange portion 18, and insert the tip end into the elongated hole in the exterior component side clip 32.
0, pull the exterior component side clip 32 toward the body 10, and tighten and fix it. Therefore, the bumper molding 12 is tightened and fixed to the body 10 via the exterior component side clip 32 and the body side clip 24. In this case, the bumper cover 26 between the bumper molding 12 and the body 10 is also tightened and fixed to the body 10 together with the bumper molding 12. In this embodiment, the molding attaching fastener 34 is divided into two, an exterior component side clip 32 and a body side clip 24, and the amount of protrusion of the exterior component side clip 32 toward the back side of the molding is small.
Moreover, since it does not protrude from the bumper cover 26, the surface of the body 10 will not be damaged during the installation work. Furthermore, in this embodiment, the clips 24,
32 and temporarily fasten the bumper molding 12, the exterior component side clip 32 is pulled toward the body 10 side using the tatu pin screw 42 and tightened and fixed, so a gap is created between the bumper molding 12 and the body 10. It can be installed with high precision without any problems. Although the above embodiment concerns the bumper molding 12 attached to the bumper cover 26, the present invention is not limited thereto, and can also be applied to general exterior parts such as moldings attached to other parts of the automobile. This applies to Further, in the above embodiment, after fitting the exterior part side clip 32 to the body side clip 24, the two are tightened and fixed with the tuft pin screw 42, but the present invention is not limited to this. However, the present invention is also applicable to a case where the exterior component is attached to the body side only by fitting the exterior component side clip to the body side clip without using screws. Furthermore, the body side tip of the exterior component side clip 32 in the above embodiment protrudes from the back surface 12A of the bumper molding 12 toward the body side, but is housed inside the back surface 26A of the bumper cover 26 overlaid thereon. In this way, the body 10 is prevented from being damaged during installation, but the exterior component side clip 32 may have any structure as long as it does not protrude to the back side of the exterior component to be attached. For example, in the case of a structure in which the bumper cover is not sandwiched between the bumper molding and the body, the exterior component side clip can be accommodated within the bumper molding.

[Effect of the idea]

Since the present invention is configured as described above, it has the excellent effect of eliminating the protrusion of the clip from the back surface of the exterior component toward the body side and preventing damage to the body side surface during assembly work. .
