Abstract
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.
