ABSTRACT:
In a method for producing a molded article having a resin part, the resin part is injection-molded to an opening of a main body part and the molded article has an excellent air-tightness between the resin part and the main body part. A foam sealant is attached to a peripheral portion around the opening of the main body part. Attached to the main body part is a retainer made of the same kind of resin as injected resin and adapted to keep the foam sealant compressed in its thickness direction. The main body part is placed within a mold so that the retainer is exposed inside a cavity of the mold. A molten resin is injected into the cavity of the mold. The injected resin and the retainer are integrated into the resin part.
