However, in such a structure of the mounting seat portion 52, as shown in FIG.
1 is mounted on the back surface 5 of the resin molded product 51 due to constraints on the shape of the base material 55 or design constraints.
It is necessary to make the distance A between 1a and the base 52a of the mounting seat 52 as narrow as possible. In addition, the resin clip 56
The base portion 52a has an undercut portion 53 to prevent the core from coming off, and the inclined core 6 forms the interval A.
2 must be formed inside the base portion 52a. Therefore, as shown in FIG. 7, the thickness B of the inclined core 62 for forming the interval A must be made extremely thin (generally 5 mm or less), and the resin molded product 51
During molding, stress concentrates on the corner portions 64 of the thick and thin portions of the inclined core 62, causing damage in a short period of time.
従つて、この考案は、上記の不具合を解消する
