ウント装置。[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, the operating member is connected to two or more hard members connected so as to be relatively displaceable in a main vibration input direction between the inner and outer cylindrical fittings via a connecting rubber elastic body. A fluid-filled cylindrical mount device characterized by comprising:
