Claims (1)

[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 outer wall rubbers, which are disposed on the outer circumferential surface of the axially central portion of the inner cylinder fitting and integrally include a mounting fitting and an outer sleeve on the inner and outer circumferential surfaces, which are positioned at a predetermined distance in the radial direction. The elastic body is attached by fixing each mounting bracket to the axial end of the inner cylinder metal fitting and sandwiching the partitioning metal fitting of the partition rubber elastic body in the axial direction between the end faces of the outer sleeve, and further A cylindrical bracket attached and fixed to a predetermined support member is fitted onto the outer circumferential surface of the outer sleeve, and the outer sleeve of the pair of outer wall rubber elastic bodies is clamped by the cylindrical bracket in opposing axial directions. The pair of outer wall rubber elastic bodies are divided into two parts in the axial direction by the partition wall rubber elastic body, and are communicated with each other in the axial direction by the orifice passage, thereby achieving a predetermined incompressibility. In a fluid-filled type vibration-damping connection body in which a fluid chamber filled with fluid is formed inside, the inner cylindrical metal fitting and the cylindrical bracket are provided with an outer wall axially outwardly of the outer wall rubber elastic body. A stopper member is integrally provided at the stopper member and extends in the radial direction toward the other side, and a stopper member is provided on the other of the inner cylindrical metal fitting and the cylindrical bracket in the axial direction and perpendicular to the stopper member. A regulating portion is formed facing each other at a predetermined distance in the direction, and a cushion layer is integrally provided on at least one of the regulating portion and the stopper member, and the stopper member is brought into contact with the regulating portion to prevent the above-mentioned 1. A fluid-filled vibration-proof connection body configured to restrict excessive displacement of an inner cylindrical metal fitting with respect to the cylindrical bracket.
