Abstract: When manufacturing an upper support which includes a cup piece as an inner piece, an outer piece, and a rubber elastic body integrally vulcanize adhered thereto, the shape of a tubular portion of a cup piece before integral vulcanized adhesion with the rubber elastic body is a shape having a large diameter portion at a top portion continuous with a flanged portion, a small diameter portion at a bottom portion, and a stepped portion therebetween. Following integral vulcanized adhesion with the rubber elastic body, only the small diameter portion is diameter widened by press-fitting a diameter widening jig to impart pre-compression to the rubber elastic body. No roll-back deformation of a flanged portion occurs when integrally vulcanize adhering the cup piece to the rubber elastic body, and also when imparting pre-compression to the rubber elastic body by diameter widening a tubular portion of the cup piece.
