ABSTRACT:
A process for producing a radiator support, disposed between a radiator and a vehicle-side installation member, includes the steps of molding a rubber-elastic member, disposing the resulting rubber-elastic member in a mold, and completing a radiator support by injecting a resinous material into the mold. In the rubber-elastic member molding step, a rubber-elastic member is molded to include a rubber flange which has a top surface and a bottom surface. In the radiator support completing step, a rigid inner tube member and a rigid outer tube member are molded integrally with the rubber-elastic member, wherein the rigid outer tube member is molded so as to include a flange which has a top surface superimposed on the bottom surface of the rubber flange of the rubber-elastic member, a bottom surface, and a cut-off. The cut-off downwardly exposes a portion of the bottom surface of the rubber flange of the rubber elastic-member in a completed radiator support. In the radiator support completing step, the downwardly-exposed portion of the rubber flange of the rubber-elastic member is held by the mold. Hence, it is possible to effectively inhibit the rubber-elastic member from being put out of position in the mold, and from being deformed by the injection pressure of the resinous material.
