A rubber 12 is vulcanized and bonded integrally with an engine side mounting member 11 and a barrel member 14 for caulking and fixing a diaphragm 16. A car body side mounting member 13 is formed by injection molding a resin material on the outer circumference of the rubber 12. A seal is provided between the barrel member 14 and the diaphragm 16 by caulking the peripheral edge part of the diaphragm 16 with the barrel member 14.
