ABSTRACT:
A fluid filled vibration damping device including an elastic body connecting a first and second mounting member, a pressure-receiving chamber defined by the elastic body and an equilibrium chamber defined by a flexible rubber film. The second mounting member is press fitted into a tubular holder member having an annular holding portion integrally formed at its lower end projecting radially inwardly. A cover plate member having an outside diameter smaller than an inside diameter of the holder member is disposed within the holder member with an outer peripheral portion is fixedly clamped by the second mounting member and the annular holding portion. A sealing rubber is disposed for fluid-tightly closing a gap formed between the clamped portion so that an tightly closed air chamber defined by the cover plate member is formed on a back side of the flexible rubber film.
