Claims

[Claims for Utility Model Registration] A first support body and a second support body arranged at a predetermined distance in one vibration input direction are connected by a rubber elastic body interposed between them. At least one of the pressure receiving chambers into which vibrations are input is placed on the side of the first support body, with a partition member supported by the second support body and arranged substantially perpendicular to the vibration input direction in between. A variable volume equilibrium chamber whose portion is defined by a flexible membrane is formed on the opposite side of the pressure receiving chamber, and a predetermined incompressible fluid is sealed in the pressure receiving chamber and the equilibrium chamber. On the other hand, an orifice passage is provided that allows the pressure receiving chamber and the equilibrium chamber to communicate with each other;
In the fluid-filled mount device, in which an umbrella member is disposed to form a constricted portion between the inner surface of the pressure receiving chamber, the rubber elastic body has a structure including a tapered cylindrical annular portion, and the annular portion The first support body is fixed to the small diameter side of the annular part, and the second support body is fixed to the large diameter side of the annular part, and an abutting member is embedded in the middle part of the annular part, and the corresponding abutting member a regulating portion having one end in the vibration input direction located opposite to the umbrella member in the vibration input direction, and located opposite to the other end in the vibration input direction of the abutting member in the vibration input direction; is integrally provided on the second support side, so that the second support of the first support is brought into contact with the regulating portion of the umbrella member via the abutment member. A fluid-filled mounting device characterized in that the amount of displacement in the vibration input direction relative to the support can be regulated.
