PURPOSE:To install a protector made of a thermoplastic synthetic resin integrally, and obtain the high adhesion of an inlet made of a metal and a main pipe without damaging molding efficiency. CONSTITUTION:An inlet 5 made of a metal covering an adhesive thermoplastic synthetic resin 14 is inserted under the state, in which the adhesive thermoplastic resin 4 is not melted, while a protector 3 is molded integrally. Accordingly, since a parison 12 is not quenched even when the parison is brought into contact with the adhesive thermoplastic synthetic resin 4, the parison 12 is fast stuck to the adhesive thermoplastic synthetic resin 14 with excellent fluidity and the state of superior adhesion is obtained, thus making a cooling time shorter than that when the adhesive thermoplastic synthetic resin 14 is heated and melted previously. |
