ト。[Claims for Utility Model Registration] An inner cylindrical metal fitting attached to one member to be connected in an anti-vibration manner, and the other member to be connected in an anti-vibration manner arranged at a predetermined distance on the outside of the inner cylindrical metal fitting. an outer cylindrical metal fitting that is attached to the member; and an outer cylindrical metal fitting that is interposed between the inner cylindrical metal fitting and the above-mentioned outer cylindrical metal fitting to elastically connect the two metal fittings, and a A central protrusion formed to protrude at a predetermined height in the direction perpendicular to the mount axis toward the cylindrical metal fitting side, and integrally extending outward in the mount axis direction from both sides of the central protrusion in the mount axis direction. a pair of side walls formed by
A pair of vertical walls integrally formed outward in a direction perpendicular to the mount axis from the extending edge of each of the horizontal walls, and a a rubber elastic body provided with a pocket portion opening outward; and a predetermined incompressible fluid formed by covering the opening of the pocket portion in the rubber elastic body with the outer cylindrical metal fitting. I was forced to enclose it,
a pressure receiving chamber in which an internal pressure fluctuation is induced based on the deformation of the rubber elastic body when vibration is input; By being positioned so as to spread out in a direction substantially perpendicular to the input direction of the vibration to be damped, the pressure receiving chamber is narrowed and divided into an inner portion and an outer portion in the direction perpendicular to the mount axis. an umbrella member that is integrally molded with the rubber elastic body and forms a constricted flow path that allows the inner and outer portions to communicate with each other, and between the inner cylindrical metal fitting and the outer cylindrical metal fitting,
a variable volume equilibrium chamber formed independently of the pressure receiving chamber, at least a portion of which is defined by a flexible membrane, and in which a predetermined incompressible fluid is sealed; A fluid-filled cylindrical mount comprising: an orifice passage provided between a pressure receiving chamber and the equilibrium chamber to allow the incompressible fluid to flow between the two chambers.
