[Scope of Claim for Utility Model Registration] An inner cylindrical metal fitting, an outer cylindrical metal fitting arranged outside the inner cylindrical metal fitting at a predetermined distance, and interposed between the inner cylindrical metal fitting and the outer cylindrical metal fitting, a cylindrical rubber elastic body that elastically connects them; a cavity that is formed through the cylindrical rubber elastic body in the axial direction and extends with a predetermined width in the circumferential direction; and the cylindrical rubber elastic body A through hole is formed in a direction perpendicular to the axial direction of the cylindrical rubber elastic body at a position opposite to the cavity with the inner cylindrical metal fitting interposed therebetween, and has openings at both ends thereof. is formed by closing with the outer cylindrical fitting,
A pressure receiving chamber into which vibrations to be damped are input; and a flexible membrane at least partially opening on the outer circumferential surface and formed at a predetermined distance in the circumferential direction from the pocket portion forming the pressure receiving chamber. A variable volume equilibrium chamber is formed by closing the opening of a pocket portion defined by the outer cylindrical fitting, and an orifice that allows the pressure receiving chamber and the equilibrium chamber to communicate with each other. a passage; a predetermined incompressible fluid sealed in the pressure receiving chamber and the equilibrium chamber; a fixed restraining member extending in the axial direction; and the cylinder formed between the restraining member and the outer cylinder fitting so as to be located further radially outward from the position where the restraining member is disposed. A narrowed portion is formed between a slit having a predetermined width passing through the shaped rubber elastic body in the axial direction and an inner surface of a peripheral wall of the pressure receiving chamber that is attached to and supported by the restraining member and protrudes into the pressure receiving chamber. 1. A fluid-filled cylindrical mount comprising: an umbrella member.
