Claims

[Scope of Claim for Utility Model Registration] An inner cylindrical metal fitting, an outer cylindrical metal fitting arranged outside the inner cylindrical metal fitting at a predetermined distance, and interposed between the inner cylindrical metal fitting and the outer cylindrical metal fitting, A rubber elastic body that elastically connects them; and a pocket provided in the rubber elastic body that is disposed at an opening of a pocket opening on the outer circumferential surface, and a fluid storage space is created by closing the opening of the pocket. a predetermined incompressible fluid sealed in the fluid storage space, and a predetermined incompressible fluid sealed in the fluid storage space; a partition member that partitions the accommodation space into a pressure receiving chamber in which an internal pressure change is caused by the input of vibration and an equilibrium chamber in which a volume change is allowed based on elastic deformation of a flexible membrane in the closing member; Inside the pressure-receiving chamber, it is supported by the inner cylindrical metal fitting and forms a narrowed part between it and the inner wall surface of the pressure-receiving chamber, and divides the pressure-receiving chamber into inner and outer parts in the radial direction of the mount with the narrowed part in between. an umbrella member that is attached to the partition wall member so as to be displaceable or deformable by a predetermined distance in a direction that absorbs a fluid pressure difference between the pressure receiving chamber and the equilibrium chamber; and the pressure receiving chamber. an orifice passage provided between the equilibrium chamber and the fluid chambers to communicate with each other;
A fluid-filled anti-vibration bushing characterized by having:
