装置。[Claims for Utility Model Registration] A first support and a second support disposed at a predetermined distance in the vibration input direction are elastically connected by a rubber elastic body, and A volume at least partially defined by a flexible membrane, with a pressure-receiving chamber into which vibrations to be vibration-isolated are inputted, on the side of the first support body, with a partition wall arranged in a substantially perpendicular direction in between. a variable equilibrium chamber on the second support side;
A predetermined incompressible fluid is sealed in the pressure receiving chamber and the equilibrium chamber, and an orifice passageway is provided between the pressure receiving chamber and the equilibrium chamber to allow the fluid chambers to communicate with each other; and a movable member arranged to be able to be displaced or deformed by a predetermined amount in a direction that absorbs a fluid pressure difference, wherein the rubber elastic body is formed to have a solid substantially truncated conical shape. The small diameter side is connected to the first support body, and the large diameter side is connected to the second support body, and at the center of the large diameter side end face, a predetermined depth extending in the vibration input direction is connected. By forming a recessed part,
A fluid-filled mounting device characterized in that the pressure receiving chamber is formed between the large-diameter end face of the rubber elastic body and the partition wall, including the recessed portion.
