Abstract:
1. A vibration damping device interposed between a first member and a second member to be connected in a vibration damping manner, comprising: a first mounting member connectable to the first member, the first member being a vibration member; a second mounting member connectable to the second member, the second member connected to the vibration member in a vibration damping manner, and having a cylindrical portion; and a rubber elastic body of generally frustoconical configuration overall, and disposed between the first and second mounting members such that the second mounting member is connected at an inner circumferential surface of the cylindrical portion thereof to a large diameter side outer circumferential surface of the rubber elastic body, and the first mounting member is separably coupled directly or indirectly to a small diameter end face of the rubber elastic body so as to exert an external load on a central portion of the rubber elastic body, wherein the first mounting member has a first abutting portion, and the second mounting member has a second abutting portion the second abutting portion being situated to be opposed to the first abutting portion with a given distance interposed therebetween in a rebound direction where the first and second mounting members move axially away from each other, and a stop rubber is bonded to at least one of the first and second abutting portions so that the stop rubber is disposed between the first and second abutting portions to provide a stopper structure, and wherein, upon input of the external load in the rebound direction, the first and second mounting members are held in a separated state with no connection therebetween, and in the stopper structure, the first and second abutting portions are brought into abutment with each other with the stop rubber compressed therebetween to thereby limit an amount of displacement between the first and second mounting members relative to each other in the rebound direction.
