Claims

[Scope of Claim for Utility Model Registration] A first mounting bracket having a bottomed cylindrical shape with a first recess formed therein, and an opening larger than the outer peripheral surface of the cylinder wall of the first mounting bracket. a second recess having a section, and the opening of the first recess in the first mounting bracket is located on the opening side of the second recess;
a second mounting bracket positioned opposite to the first mounting bracket at a predetermined distance; an outer circumferential surface of the cylindrical wall portion of the first mounting bracket; an annular rubber elastic body interposed between the inner circumferential surface of the recess and connecting the first mounting bracket and the second mounting bracket to each other; and a first recess in the first mounting bracket. a partition member disposed in the opening of the recess and partitioning the inside and outside of the first recess by covering the opening; and a second mounting member located on one side with respect to the partition member. A part of the wall formed in the second recess of the metal fitting is made of the rubber elastic body, and a predetermined incompressible fluid is sealed inside, causing internal pressure fluctuations when vibration is input. a pressure receiving chamber, located on the other side with respect to the partition member and formed in a first recess in the first mounting bracket, at least a portion of which is formed of a flexible membrane, and whose volume changes. an equilibrium chamber in which a predetermined incompressible fluid is sealed, and an equilibrium chamber is formed between the pressure receiving chamber and the equilibrium chamber;
A fluid-filled mounting device characterized by having an orifice passageway that allows fluid to flow between the two chambers.
