  Hereinafter, a clip body (end cap) 1 used in an embodiment of the present invention will be described with reference to the drawings, and a molding formed by attaching the clip body 1 to a molding body 5 will be described. The molding formed by attaching the clip body 1 to the molding body 5 is attached to the upper edge portion of the outer panel 70 as illustrated in FIG. 7C. Here, when mounting the molding, the clip piece 12 projecting from the opening 50 (see FIG. 5A) of the molding body 5 is attached to the locking receiving portion (non-removable portion) provided at the corresponding portion on the outer panel 70 side. This is done by locking to the figure.

  As shown in the general cross section of FIG. 7A, the molding body 5 is formed by attaching an upper lip 58, a lower lip 59, and the like to a core material 51 made of metal (eg, SUS). In the drawing, reference numeral 510 denotes a part exposed to the outside of the vehicle body to be a design surface. Since the structure of the general cross section (a cross section of a normal part excluding the end portion) and the lip of the molding body 5 and the lip are well known, further explanation is omitted.

  The clip body (end cap) 1 is made of a synthetic resin (eg, polyacetal, polypropylene, etc.), and as shown in FIG. 1 and the like, a base 11, a clip piece 12 projecting from the base 11, a base 11 and a clip It consists of the cover body 14 comprised separately from the piece 12. FIG.

  The base 11 has a shape along the longitudinal direction of the molding main body 5, and the molding main body from the side of the end 5 a (see FIGS. 6 and 7C) of the molding main body 5 starting from one end 11 a. 5 is inserted into the interior. That is, it is attached to the mall body 5.

  The caulking receiving portion 13 is located on the base 11 near the base of the clip piece 12 (near the one end 11a), and the caulking piece 513 (see FIGS. 5 (f) and 6 (b)). ). The concave portion (caulking receiving portion) 13 is defined by wall portions 135 and 136 in the longitudinal direction of the base portion 11. In the figure, 132 is a through-hole provided in the crimping receiving portion 13, and has an effect of releasing the deformation of the base 11 due to the pressure contact force of the crimping piece 513.

  On the pressure contact surface (surface pressed by the caulking piece 513) 130 of the caulking receiving portion 13, a plurality of streaky convex portions 130 a and streaky concave portions 130 b as easily collapsible uneven portions are provided in the longitudinal direction of the base 11. (See FIGS. 1A and 3B).

  After the base portion 11 is inserted (attached) into the molding body 5, the lid body 14 is fitted to the end portion 5a of the molding body 5, and then the crimping pieces 513a, 513, 513b (see FIG. 6B) are inserted. It is bent with a punch and is brought into pressure contact with caulking receiving portions 140A, 13, and 130B (see FIG. 1A) provided at corresponding portions of the lid 14 and the base 11, respectively. Thereby, the lid body 14 and the base portion 11 (and the clip piece 12 integral with the base portion 11) are fixed to the molding body 5. The caulking receiving portions 140 </ b> A and 130 </ b> B are recessed portions formed in the lid body 14 and the base portion 11, respectively, similarly to the caulking receiving portion 13.

At the time of the above-described press contact, the crimping piece 513 crushes the line-like convex portion 130 a formed on the pressed surface 130 of the crimping receiving portion 13. As a result, the crushed lump protrudes from the edge of the caulking piece 513 to become a lump, and the edge of the caulking piece 513 is pressed. This function and effect is reliably achieved because the streaky convex portion 130 a is along the longitudinal direction of the base portion 11 and is always in close contact with the edge of the crimping piece 513. In this way, firm fixation of the base 11 is realized. Similar to the pressure contact surface of the caulking receiving part 13, a streak-like concave part and a streaky convex part may be provided on the pressure contact surface of the caulking receiving part 140 </ b> A or 130 </ b> B to achieve the same effect. Of course.
Further, after the crimping piece 513 is bent by the punch, when the clip body 1 is further pushed into the molding body 5, the clip body 513 is not folded (or when the crimping piece 513 is folded). When the body 1 is pushed into the molding body 5, crushing of the streaky convex portion 130 a may occur.

  In the above description, the example in which the easily crushed uneven portions (the streaky convex portion 130a and the streaky concave portion 130b) are provided on the pressed surface 130 of the caulking receiving portion 13 has been described. Next, the wall portion 135 of the caulking receiving portion 13 is described. , 136 will be described in the case where an easily crushed uneven portion (a streak-like convex part and a streak-like concave part) is formed.

  For example, a streaky convex portion 135a and a streaky concave portion 135b as schematically shown in FIG. 7B are formed in the vicinity of the wall portion 135 (136) of the caulking receiving portion 13, and the caulking piece 513 is formed by punching. When the streak-shaped convex portion 135a is crushed at the same time as bending, the lump that is crushed and protrudes presses the edge of the caulking piece 513, and the same effects as those described above can be achieved. The same applies to the wall 136.

  Further, in this example, the base 11 and the lid 14 are separate, but when they are integrated, the wall 135 of the caulking receiving portion 13 (the side far from the end of the molding body 5 = the base 11 above) In the case where the easily crushed uneven portions (the streaky convex portion 135a and the streaky concave portion 135b) are formed on the one end portion 11a) and the base portion 11 is crushed by the crushing force. Since it is drawn toward the inside of the molding body 5, there is an effect that it is possible to prevent a gap from being generated between the lid body 14 and the end portion 5 a of the molding body 5. In addition, a streak-like concave part and a streak-like convex part are provided on the wall parts of the caulking receiving part 140A and 130B and the vicinity thereof in the same manner as the wall parts 135 and 136 of the caulking receiving part 13 and the vicinity thereof, and similar effects are obtained. Of course, it may be allowed to.
