Abstract
A fluid-filled vibration damping device includes: an elastic body connecting a first mounting member and a second mounting member; and a partition member assembled with the second mounting member to form on its opposite sides a pressure receiving chamber partially defined by the elastic body and an equilibrium chamber partially defined by a flexible layer, both being filled with non-compressible fluid. The partition member defines an orifice passage connecting the two chambers, and including a first partitioning wall portion partitioning the orifice passage from the pressure-receiving chamber, and a second partitioning wall portion of rubber partitioning the orifice passage from the equilibrium chamber. A partial reinforcing member is provided to the partition member extending across the first and second partitioning wall portions to reinforce an opening of the orifice passage to the pressure-receiving chamber.
