PURPOSE:To injection-mold a covering layer without deteriorating the appearance of the surface of an elastic body also, while its burrs may be suppressed suficiently and simply. CONSTITUTION:In this method, the covering layer 2 of thermoplastic resin is injection-molded on the surface 4b of an elastic body. While the mold-position 6a for injection molding which forms sealing part 7 with the surface 4b of the elastic body is kept at lower temperature than that of the other mold position for injection molding, the covering layer 2 is molded characteristically. |
