PROBLEM TO BE SOLVED: To extremely strongly bond vulcanized rubber and a synthetic resin, by preliminarily forming a vulcanized adhesive layer for enhancing abhesiveness to vulcanized rubber to arrange the rubber in a mold and injecting a molten resin into the mold in such a sate that the mold is heated to specific high temp. SOLUTION: A vulcanized adhesive based on chlorosulfonated polyethylene is applied to a synthetic resin blanket main body 2 and a bush-shaped vibration- proof rubber elastomer 3 by a brush or a sprayer in order to bond both of them and dried by air to form a first vulcanized adhesive layer. Next, a vulcanized adhesive based on a phenolic resin is applied to the first vulcanized adhesive layer to form a second vulcanized adhesive layer. Then, a synthetic resin is injected into a mold for molding a synthetic resin in such a state that the mold is heated to 100-130 deg.C. By this constitution, the first vulcanized adhesive layer shows strong adhesiveness to vulcanized rubber and the second vulcanized adhesive layer can develop strong adhesive action between the first vulcanized adhesive layer and the synthetic resin. |
