Abstract
A fluid-filled vibration-damping device includes an elastic body elastically connects a first mounting member and a cylindrical second mounting member bonded to opposite side thereof; a diaphragm supported by the second mounting member so that the diaphragm cooperates with the elastic body to define therebetween a fluid chamber; and a partition member supported by the second mounting member so that the partition member divides the fluid chamber into a primary fluid chamber and an auxiliary fluid chamber which are held in communication through an orifice passage defined by an orifice-defining member having a movable rubber plate disposed in its central hole. The surface of the orifice-defining member is coated at a primary-fluid-chamber-defining area by a coating rubber layer, thereby minimizing noises caused by bubbles in the fluid chamber.
