Claim:
A fluid-filled vibration damping mount of suspension type, comprising: a first mounting member; a second mounting member having a generally hollow cylindrical configuration whose lower open end portion is situated about the first mounting member, a generally tapered elastic body elastically connecting the first and second mounting members together, the elastic body extending from the lower open end portion of the second mounting member to an inside of the second mounting member, and fluid-tightly closing the lower open-end portion of the second mounting member; a flexible layer fluid-tightly closing an upper open-end portion of the second mounting member for forming a fluid chamber defined between the elastic body and the flexible layer and filled with a non-compressible fluid; a partition member disposed within the fluid chamber so as to extend in an axis-perpendicular direction of the second mounting member, and fixedly supported at an peripheral portion thereof by the second mounting member, for fluid-tightly dividing the fluid chamber into a pressure-receiving chamber partially defined by the generally tapered elastic body and an equilibrium chamber partially defined by the flexible layer; an orifice passage for permitting a fluid communication between the pressure-receiving chamber and the equilibrium chamber; and a pair of restricting projections each being bonded to the partition member and projecting from the partition member into the pressure-receiving chamber so as to be situated in a region defined by and between an outer circumferential surface of the elastic body and an inner circumferential surface of the second mounting member for restricting the region, the pair of restricting projections being situated at respective circumferential positions mutually opposed in the axis-perpendicular direction of the second mounting member, and extending substantially circumferentially with a circumferential length smaller than a half of a circumference of the partition member, wherein the pair of restricting projections are arranged to be spaced away from the elastic body and the second mounting member, and wherein each of the restricting projections has an angular length smaller than 180 degrees about a center axis of the second mounting member.
