Claims

[Scope of Claim for Utility Model Registration] An inner cylindrical metal fitting and an outer cylindrical metal fitting arranged concentrically or eccentrically at a predetermined distance in the radial direction are made elastic by a rubber elastic body interposed between them. At the same time, a predetermined incompressible fluid is sealed between the inner cylindrical metal fitting and the outer cylindrical metal fitting to form a fluid chamber into which vibrations to be damped are input, and further inside the fluid chamber. , movably housing an action member that forms a vibration action part with a predetermined gap between it and the inner surface of the fluid chamber;
In the fluid-filled cylindrical mount device, each opening is opened at a pair of axial end faces located on both sides of the mount in the axial direction of the action member, and a space is formed between each of the axial end faces and the inner surface of the fluid chamber. connecting passages that communicate the gaps formed between the other axial end surface or a surface other than the axial end surface and the fluid chamber inner surface, respectively;
A fluid-filled cylindrical mount device characterized in that it is provided by penetrating the inside of such an operating member.
