Claims (1)

[Claims for Utility Model Registration] For an inner cylindrical fitting into which a predetermined shaft member is inserted and attached, a partitioning fitting having an orifice passage formed inside thereof is integrally formed on the outer peripheral surface of the inner cylindrical fitting through which a predetermined shaft member is inserted. A pair of annular rubber elastic bodies each having a mounting bracket and an outer sleeve integrally provided on the inner and outer circumferential surfaces, which are spaced apart from each other by a predetermined distance in the radial direction, are arranged. The mounting bracket is press-fitted into the axial end of the inner cylindrical metal fitting, and the partitioning metal fitting of the cylindrical rubber elastic body is mounted between the end faces of the outer sleeve in such a manner that it is sandwiched in the axial direction, and the outer circumference of the outer sleeve is further fixed. A cylindrical bracket, which is attached and fixed to a predetermined support member, is fitted onto the surface, and the outer sleeves of the pair of annular rubber elastic bodies are squeezed in the opposing axial directions by the cylindrical bracket. A fluid which is divided into two parts in the axial direction by a cylindrical rubber elastic body and which are communicated with each other through the orifice passage, and has a fluid chamber filled with a predetermined incompressible fluid formed inside. In the enclosed type vibration-proof support, the cylindrical wall portion of the cylindrical rubber elastic body is bellows-shaped, and the inner circumferential surface of the cylindrical rubber elastic body is in a non-adhered state to the outer circumferential surface of the inner cylindrical metal fitting. and place it in
It is characterized in that it is attached to both axial ends of the inner cylindrical fitting by sandwiching both axial ends thereof between the inner cylindrical fitting and the mounting fitting of the annular rubber elastic body. Fluid-filled anti-vibration support.
