Claims

[Claims for Utility Model Registration] An inner cylindrical member; an outer cylindrical member disposed outside the inner cylindrical member; a cylindrical elastic member interposed between the inner cylindrical member and the outer cylindrical member; ; two types of fluid chambers formed within the elastic member and arranged apart from each other in the axial direction; orifice means for communicating the two types of fluid chambers; a predetermined fluid chamber sealed within the two types of fluid chambers; A fluid-filled vibration-isolating bushing having an incompressible fluid and damping vibrations based on flow resistance when the incompressible fluid flows through the orifice means, the axial direction of the elastic member Annular restraining members are provided on the inner periphery of both ends, integrally with the elastic member and fixed in position on the inner cylinder member, and the restraining members restrict the inner periphery of the elastic member at both ends in the axial direction. A fluid-filled vibration-proof bushing characterized in that the inner cylinder member is restrained.
