PURPOSE:To prevent deformation of a rubber elastic body and a fluid chamber by engaging a pair of metal sleeves arranged oppositely to each other on an outer peripheral surface of the rubber elastic body with an engagement part provided on an outer- cylinder fitting on the respective opposed surfaces, and thereby preventing relative displacement of the metal sleeves in an approaching direction. CONSTITUTION:In a device main body, a cylindrical rubber elastic body 24 is vulcanizingly adhered to an outer peripheral surface of an inner-cylinder fitting 10. A pair of metal sleeves are vulcanizingly adhered to an outer peripheral surface of the rubber elastic body 24 at their both sides in an axial direction. A pocket part 32 extending in a circumferential direction and opened between the metal sleeves 18 are is formed. An outer-cylinder fitting 34 is fitted to from outside of an outer peripheral surface of the rubber elastic body 24, which is further fitted to the metal sleeves 18. The pocket part 32 is thus blocked to form a fluid chamber 36. In this case, a circular projecting part 28 as an engagement part, which is reduced in its diameter while being bent inward in a diameter direction is provided on an axially center part of the outer-cylinder fitting 34. The metal sleeves 18 are indirectly abutted against each other axially through the circular projection part 28. |
