されている。BACKGROUND ART Referring to FIGS. 1 to 4, some moldings M for vehicles are made of resin, which is obtained by extruding ABS or PVC into a long length, and then cutting the molding into a predetermined size. This molding body is, for example, the surface part.
m 1 and the left and right sides continuous from its surface m 1
m 2 , m 3 and a leg section m 4 that stands up approximately at the center on the inner surface of the surface section m 1 and exhibits a relatively thin and irregular cross-sectional shape, with one side section m 4 and a leg section m It is attached to the vehicle body B by sandwiching the flange F between the two parts. In addition, this molding M has an end cap E attached to its terminal, and a clip C fixed to the inside of the end cap is hooked and held by the head of a stud S protruding from the panel surface of the vehicle body B. .

容易に剥離してしまう欠点がある。 By the way, conventionally, the end cap E is separately molded and fixed to the end of the molding M which is cut straight across the axis of the molding M using an adhesive. However, with this end cap E, the contact area between each end face is small, so the adhesion strength cannot be maintained sufficiently, and what is more, if the main body of the molding shrinks over time while supported by the stud S, the gap between the two may easily occur. It has the disadvantage of peeling off.

A desired length of notch is removed along the inside in the longitudinal direction, and the molded resin of the end cap is bonded to the notch and the remaining end portion, and a part is extended to the inside in the longitudinal direction of the molding to form the legs. An end cap that covers even the remaining portion after the notch has been removed is integrally fixed and molded by injection molding, and at the same time, a recess into which a clip is fitted and fixed is provided on the inner surface of the end cap portion formed in the notch.

側の内面に接着剤を予め塗布するとよい。 First, this molding M is processed to partially cut and remove the end portion along the inside in the longitudinal direction. Thereafter, along the longitudinal direction of the molding M, a notch is removed from the leg m4 to the side m3 to a desired length (see line x--x in Figure 5), and in the leg m4 , the U It may be cut out in a letter shape (see Figure 6). A milling machine or a press mold can be used for this cutting, and after cutting, the leg portion m 4 is partially left at the end portion of the molding M. Next, an end cap E is formed on the partially cut end by injection molding. The molding can be carried out by inserting the end side of the molding M into the molds L 1 and L 2 , clamping the molds, and injecting the resin into the cavity space (Fig. 7). reference). It is preferable to use the same PVC resin as the resin with which the surface side of the main body of the molding M is coated and molded for this injection resin, and it can be welded to the wide cut end surface of the end of the molding and firmly fixed. In addition, this resin extends inward in the longitudinal direction from the end of the molding M and covers the inner surface of the leg portion m 4 that remains partially, and also covers the inner surface near the residual limb edge on the left and right sides of the leg portion m 4 . By forming the resin layer e 1 , it becomes possible to completely fuse with each other and firmly bond each other (No. 8)
(see figure). In addition, when the injection resin and the core of the molding M do not exhibit good compatibility, it is preferable to apply an adhesive to the inner surface of the core in advance.

Fix C with adhesive (see Figure 9). Also, to attach the molding M to the vehicle body B, as in the case shown in FIG. It can be latched by the head of the stud S that protrudes from the surface (see Fig. 10). When the molding M is fixed to the panel surface of the vehicle body B by the stud S via the clip C, the recess e2 into which the clip C is fitted and fixed is located in the longitudinal direction on the inner surface of the molding M, so that the molding M is fixed in the longitudinal direction. It is possible to sufficiently withstand not only the tensile force on the vehicle body B side but also the tensile force on the side of the vehicle body B, and stable installation can be performed.

んどに広く適用することができる。 In this end cap installation method, the main body of molding M is attached to end cap E.
Since the end cap E is formed by protruding into the inside of the molding body and extending to cover the inner surface of the molding body from which the leg m4 has been cut out, the decorativeness is improved by making the protruding part of the end cap E smaller. Moreover, by increasing the mutual contact area, strong adhesion can be obtained. Note that there are many types of molding M with different cross-sectional shapes, and this end cap attachment method can be widely applied to most of them.

のである。Effects of the Invention As described above, according to the method of attaching an end cap to a resin molding according to the present invention,
By joining the end cap and the molding body with a large contact area and making them integral, it prevents them from peeling off from each other, and it can be attached to the panel surface of the vehicle body with a clip that can be securely fixed to the panel surface of the vehicle body. This improves the durability of the molding.
