Claims

[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 them; (e) a pocket portion of the cylindrical rubber elastic body that opens on the outer circumferential surface and is formed at a position opposite to the void space while sandwiching the inner cylindrical metal fitting; (f) a pressure receiving chamber into which vibrations to be damped are input, which is formed by closing with the outer cylindrical metal fitting; and (f) a predetermined distance in the circumferential direction from the pocket portion forming the pressure receiving chamber. A pocket portion, which is formed at a separate position and has an opening on the outer circumferential surface and at least a portion of which is defined by a flexible membrane, is formed by closing the opening with the outer cylindrical metal fitting. , a volume-variable equilibrium chamber, (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 rubber elastic body is provided with a through hole of a predetermined width that is located between the inner cylindrical fitting and the pressure receiving chamber and penetrates in the axial direction; A restraining member extending in the axial direction and located outwardly from the through hole in the radial direction of the elastic body is integrally embedded, and a peripheral wall portion of the pressure receiving chamber protrudes into the pressure receiving chamber with respect to the restraining member. A fluid-filled cylindrical mount characterized by having an umbrella member erected to form a narrowed portion between the inner surface and the inner surface.
