Claims

[Claims for Utility Model Registration] A first support body and a second support body arranged at a predetermined distance from each other are elastically connected by a rubber elastic body, and the first support body and the second support body are By forming a fluid accommodating space in which a predetermined incompressible fluid is sealed between the second support body and partitioning the fluid accommodating space with a partition member disposed inside the fluid accommodating space. On both sides of the partition member, a pressure receiving chamber is defined at least partially by the rubber elastic body and into which vibrations to be damped are input, and a pressure receiving chamber is defined at least partially by the flexible membrane. An orifice passageway is provided to communicate the pressure receiving chamber and the equilibrium chamber with each other. , and a space is provided that communicates with the pressure receiving chamber and the equilibrium chamber through communication holes formed in both side partition walls, and a movable plate that can be displaced a predetermined distance between the both side partition walls is provided in the space. In the fluid-filled mounting device that is housed and arranged, at least a portion of the movable plate that contacts the partition wall of the cavity is made of a rubber elastic body, and
At least the abutment surface of the partition wall, in which the movable plate is accommodated, and which the movable plate comes into contact with and restricts its displacement, is covered with a buffer rubber layer having a predetermined thickness. Fluid-filled mounting device.
