Fluid -filled vibration damping device and method of producing the same

摘要

Disclosed is a fluid-filled vibration damping device including a first mounting member and a cup-shaped second mounting member elastically connected by an elastic body such that an opening of the second mounting member fluid-tightly closed by the elastic body. An outer metal sleeve having an outward flange portion at its upper end is bonded by vulcanization to an outer circumferential surface of the elastic body, and a cylindrical orifice member is fitted onto the outer metal sleeve with an upper end face superposed on the outward flange portion. The outer metal sleeve and the orifice member are fitted into the cylindrical wall portion of the second mounting member. An outer metallic ring bonded by vulcanization to an outer periphery of the elastic rubber layer is superposed on an axially upper surface of the outward flange portion portion, and firmly fitted into an open end portion of the cylindrical wall portion of the second mounting member.
