ABSTRACT:
A fluid-filled vibration-damping mount of suspension type, wherein a lower open-end of a second mounting member is fluid-tightly closed by a first mounting member and a tapered elastic body interposed therebetween. An upper open-end portion of the cylindrical portion is closed by a flexible layer for forming a fluid chamber between the elastic body and the flexible layer, which is divided by a partition member into a pressure-receiving chamber defined by the elastic body and an equilibrium chamber defined by the flexible layer, which are mutually communicated through an orifice passage. A pair of elastic restricting projections bonded to the partition member at respective circumferential positions with a circumferential length smaller than a half of a circumference of the partition member, project toward a circumferential region defined between the elastic body and the second mount member, for narrowing the region.
