ABSTRACT:
A fluid-filled vibration-damping device including an elastic body elastically connecting a first and a second mounting member, a pressure-receiving chamber disposed inward of and partially defined by the elastic body, and a flexible rubber layer disposed outwardly of and cooperating with the elastic body to form an equilibrium chamber held in fluid communication with the pressure-receiving chamber through a first orifice passage. The first mounting member includes an elastic-body central member and a rubber-layer central member, which are fixed together at their abutting surfaces by a fixing mechanism, to constitute the first mounting member, and positioned relative to each other by an engagement of a fitting recess and projection formed on their abutting surfaces. A peripheral portion of an interface between the abutting surfaces of the elastic-body central member and said rubber-layer central member entirely faces the equilibrium chamber and/or the pressure-receiving chamber.
