ABSTRACT:
A fluid filled vibration damping device including: an elastic body elastically connecting a first and a second mounting member and partially defining a pressure receiving chamber filled with a non-compressible fluid; a flexible diaphragm partially defining an equilibrium chamber filled with the non-compressible fluid and connected to the pressure-receiving chamber via an orifice passage. The first mounting member includes an elastic-body-side central member bonded to the elastic body central portion, and a rubber-layer-side central member bonded to the flexible rubber layer central portion, both mutually superposed on and fastened together by a connecting bolt. A fitting recess and projection are formed at an interface between two members, and a mounting projection projecting outward on an opposite side from the interface. The connecting bolt is off-centered from a center of the two members by a give distance.
