PURPOSE:To restrain relative displacement between the axial center and right angle directions so as to improve seal and durability properties by housing an independent stopper member in a fluid chamber as well as monolithically arranging a metal sleeve at the outer peripheral face of a resilient member. CONSTITUTION:A rubber sleeve 8 has a ring made of two thin metal cylinders, at the outer peripheral face at both ends. In a fluid chamber 16, a metal stopper member 26 is housed in a state that it is not fixed or suspended by any one of an outer cylindrical metal member 6, an inner cylindrical metal member 4, and a rubber sleeve 8. When a large oscillation load is generated between the members 4, 6, and large displacement is generated between them in the direction vertical to the axial center, and then the rubber sleeve 8 is greatly deformed. As a result, the stopper face of the stopper members 26 abuts against rubber layers 14, 24 so as to restrain the deformation. |
