ト。[Scope of Claim for Utility Model Registration] (a) An inner cylindrical metal fitting, (b) an outer cylindrical metal fitting arranged at a predetermined distance on the outside of the inner cylindrical metal fitting, and (c) the inner cylindrical metal fitting and the outer cylindrical metal fitting. (d) a cylindrical rubber elastic body interposed between the cylindrical rubber elastic body and elastically connecting the cylindrical rubber elastic body;
a space extending with a predetermined width in the circumferential direction; and (e) a pocket portion of the cylindrical rubber elastic body that opens on the outer circumferential surface and is formed at a position facing the space with the inner cylindrical metal fitting interposed therebetween. (f) a pressure receiving chamber into which vibrations to be damped are input, which is formed by closing the opening with the outer cylindrical fitting; and (f) a pocket portion forming the pressure receiving chamber. A pocket portion formed at a predetermined distance in the direction and opening on the outer circumferential surface is formed by closing the opening with the outer cylindrical metal fitting, and at least a portion thereof is formed by a flexible membrane. an equilibrium chamber with a variable volume defined by (g
) an orifice passage that allows the pressure receiving chamber and the equilibrium chamber to communicate with each other, and (h) a predetermined incompressible fluid sealed in the pressure receiving chamber and the equilibrium chamber, respectively;
In the fluid-filled cylindrical mount, the cylindrical mount is brought into pressure contact with the inner cylindrical fitting through a rubber layer of a predetermined thickness, and a compressive force in a radial direction is applied to a portion on the side where the pressure receiving chamber is formed with respect to the rubber elastic body. a stopper member that generates this is located in the cavity of the rubber elastic body and interposed between the inner cylindrical metal fitting and the outer cylindrical metal fitting;
Fluid filled cylindrical mount.
