Color molded. In this case, it is advantageous that the end of the thermoplastic elastomer at the joint surface between the cover of the housing and the main body is made convex over the entire joint surface. By forming the packing in this manner, the convex portion of the packing is compressed at the joint surface between the housing cover and the main body only by joining the housing cover and the main body, and the sealing property is completed.

完全にシールする。The casing cover 1 made of a thermosetting resin molded in advance is placed in a mold, and the thermoplastic elastomer is injected and thermally fused by two-color molding. The waterproof packing 2 is made. The entire peripheral end of the housing cover 1 is bent inward to form a bent end 5. At the opening of the housing body 3, a lateral groove is formed over the entire circumference to form an engaging portion 6, and the bent end portion 5 of the housing cover is connected to the engaging portion 6 of the housing body. And press-fit. Further, a belt-shaped convex portion 4 is formed over the entire circumference of the joint surface a of the bent end portion 5 of the waterproof packing 2 made of a thermoplastic elastomer with the housing cover. Therefore, when the housing cover 1 and the housing main body 3 are connected as shown in FIG. 2, the projections are compressed, and the joint surface a is completely sealed.

全となっている。According to the present invention, since the thermoplastic elastomer is molded in two colors as a waterproof packing, it is possible to omit the step of separately preparing the packing or applying the liquid packing material as in the related art, and the cost is reduced. Since the waterproof packing seals the joint surface between the housing cover and the housing main body by compressive deformation of the convex portion, the waterproofness is complete.
