Claims

[Claims for Utility Model Registration] An inner cylindrical member having a bottomed cylindrical shape into which a predetermined shaft member is inserted and attached; A bottomed cylindrical outer cylinder member is attached to a predetermined mounting member to which the members are to be connected, and the inner cylinder member and the outer cylinder member are connected and integrated at the opening side end, and between the opening side ends. a cylindrical connecting elastic body that forms a bottomed cylindrical fluid storage space between the two members by liquid-tightly closing a gap; and a predetermined viscous fluid sealed in the fluid storage space; A fluid accommodating space located within the fluid accommodating space and integrally provided on the outer circumferential surface of the inner cylindrical member or the inner periphery of the outer cylindrical member in a state of protruding in the radial direction, and interfacing with the protruding tip surface thereof. a first acting part made of a cylindrical elastic body that forms a circumferentially continuous first constriction gap with an inner wall surface; a bottom part of the inner cylinder member located in the fluid accommodation space; a second constriction gap that is integrally provided on the outer surface or the inner surface of the bottom part of the outer cylinder member in a state of protruding in the axial direction, and extending in the direction perpendicular to the bush axis between the protruding tip surface and the inner wall surface of the fluid accommodation space; 1. A viscous fluid-filled bushing comprising: a second acting part made of a plate-like elastic body, which forms a second acting part.
