A fluid filled vibration-damping device includes an elastic body disposed between a first mounting member and a second mounting member and partially defines a fluid chamber having a non-compressible fluid sealed therein, and exhibits vibration damping action on the basis of flow action of the non-compressible fluid created within the fluid chamber during vibration input. At least one mounting member from among the first and second mounting members is formed independently of the elastic body and is disposed in abutment with the elastic body in an initial load acting direction, while making the mounting member displaceable away from the rubber elastic body in a opposite direction from the initial load acting direction. A rebound stop mechanism for limiting displacement of the mounting member away from the rubber elastic body in a cushion-wise fashion is disposed between the first and second mounting members.

Fluid filled vibration damping device

A vibration damping device having a stopper structure includes: a rubber elastic body of generally frustoconical configuration overall; a first mounting member formed independently of the rubber elastic body, and directly or indirectly superimposed on the rubber elastic body in an external load input direction; and a second mounting member including a cylindrical portion that is bonded to a large diameter side outer circumferential surface of the rubber elastic body. A first and second abutting portions of the first and second mounting members are situated to be opposed to each other in a rebound direction with a given distance interposed therebetween, and a stop rubber is disposed between the first and second abutting portions so that the first and second abutting portions come into abutting contact with each other in a cushion-wise fashion, via the stop rubber to thereby provide a stopper structure.
