Claims

[Scope of Claim for Utility Model Registration] An inner cylindrical metal fitting and an outer cylindrical metal fitting arranged at a predetermined distance in the radial direction are integrally connected by a cylindrical rubber elastic body interposed between them. , a fluid chamber filled with a predetermined incompressible fluid is formed between the inner and outer cylindrical fittings on both sides of the inner cylindrical fitting in the radial direction, which is the vibration input direction, and further between these fluid chambers. In the fluid-filled cylindrical mount provided with an orifice passage that allows the flow of fluid, the rubber elastic body has a space between the inner cylindrical fitting and the fluid chambers formed on both sides of the inner cylindrical fitting in the radial direction, respectively. A cavity is provided that extends in a direction substantially perpendicular to the vibration input direction and penetrates in the axial direction, and a wall portion of the fluid chamber is connected to the inner cylindrical metal fitting in at least one of the cavities. an elastic connecting portion connected to the side, and a stopper portion protruding from the bottom of the fluid chamber at a predetermined height in the vibration input direction in the fluid chambers on both sides, respectively, is integrally provided with the rubber elastic body. Features a fluid-filled cylindrical mount.
