ABSTRACT:
A method wherein, when a multi-injection molded body made of at least a first and a second resins is molded, catching means are formed generally by pressing a part of the surface about an opening of a concave section formed in a first molded body made of the first resin to project interior side wall faces of the concave section inward, and injecting a second resin to mold a second molded body in the concave section. The multi-injection molded body thus formed has catching means in the concave section, so that the second molded body is tightly fixed to the first molded body.
