Abstract:
1. A fluid filled vibration damping device comprising: a first mounting member; a second mounting member having a cylindrical portion; a main rubber elastic body elastically connecting the first and second mounting members; a partition member supported by the second mounting member; a pressure-receiving chamber in which a non-compressible fluid is sealed that is located on one side across from the partition member and whose wall is partially defined by the main rubber elastic body; an equilibrium chamber in which the non-compressible fluid is sealed that is located on another side across from the partition member and whose wall is partially defined by a flexible film; and an orifice passage that connects the pressure-receiving chamber and the equilibrium chamber to each other, wherein the first mounting member is fixed to one end of the main rubber elastic body, and an insertion metal fitting in a cylindrical shape is fixed onto an outer peripheral face of another end thereof, and the cylindrical portion of the second mounting member is bonded by pressure to the insertion metal fitting with a sealing rubber in between in a fluid-tight manner, wherein the insertion metal fitting is provided with an inward protrusion where part of a wall portion protrudes inward, and wherein a sealing rubber storage space is formed between the inward protrusion and the cylindrical portion of the second mounting member.
