Claims

[Scope of Claim for Utility Model Registration] An annular partition rubber elastic body integrally provided with a partition fitting forming an orifice passage on the outer periphery of an inner cylindrical fitting into which a prescribed shaft member is inserted and attached. A pair of annular fittings integrally provided on the inner and outer circumferential portions of the inner and outer fittings are fixedly disposed on the outer circumferential surface of the axially central portion of the inner cylinder fitting, and are spaced apart from each other by a predetermined distance in the radial direction. each of the outer wall rubber elastic bodies is press-fitted and fixed to the axial end of the inner cylinder fitting, and the partition fitting of the partition wall rubber elastic body is axially clamped between the end surfaces of the outer sleeve. Attachment, and further fitting a cylindrical bracket attached and fixed to a predetermined support member onto the outer circumferential surface of the outer sleeve, so that the outer sleeves of the pair of outer wall rubber elastic bodies face each other with the cylindrical bracket. By applying pressure in the axial direction, the pair of outer wall rubber elastic bodies are divided into two parts in the axial direction by the partition rubber elastic body, and are communicated with each other in the axial direction by the orifice passage. In the fluid-filled vibration damping support assembly in which a fluid chamber filled with a predetermined incompressible fluid is formed inside, both axial side surfaces of the partition rubber elastic body are inclined in the same axial direction. such that the partition rubber elastic body extends radially outward from the outer peripheral surface of the inner cylinder fitting at a predetermined inclination angle;
A fluid-filled vibration-proof support assembly characterized by comprising:
