ABSTRACT:
A structural member comprising a main body molded of synthetic resin, an insert portion molded from a engineering plastic having better functional properties at least in respect of strength than those of an ordinary synthetic resin and a metallic reinforcement ring entirely embedded in the structural member between the main body and the insert portion is disclosed. The foremost end part of another member is threadly engaged with a plurality of female threads around the inner surface of the insert portion or press fitted into the insert portion. A method of producing a structural member of the foregoing type is practiced by employing an injection molding process by way of a first step of placing a metallic reinforcement ring in a first molding die for forming an insert portion and then injecting a engineering plastic in the first molding die and a second step of placing an assemble of the insert portion and the reinforcement ring in a second molding die for forming a main body of the structural member and then injecting a synthetic resin in the second die.
