Abstract
PURPOSE:To prevent a clearance liable to be generated between the metal fitting and the body of a molded article, by molding integrally the body of the molded article and the covering part of the metal fitting in blow molding of a hollow molded article having metal fitting protruding outward. CONSTITUTION:In manufacturing a hollow molded article having a metal fitting 2 protruding outside of the body 1 of the molded article, e.g. a head rest insert, the covering part 3 of the metal fitting composed of a thick wall part 3a and a thin wall part 3b is formed at the same time as blow molding of the body 1 of the molded article, so as the thin wall part 3b continues to the body 1 of the molded article and the covering part 3 adheres to the metal fitting 2 ranging from the surface of the body 1 of the molded article to the height l. By providing the metal fitting covering part 3 integrated with the molded article body 1 as above mentioned, the thin wall part 3b of the metal fitting covering part deforms and absorbs contraction, even if a clearance occurs between the body and the metal fitting part due to resin contraction after molding, and contact of the thick wall part 3a and the metal fitting part 2 is maintained well.
