Patent ID: 8061694

Claim:
A vibration isolation device comprising: a first main body member formed in a ring shape, and to be connected to a vibration receptive part; a rod-like connection member penetrating through the inner circumferential side of the first main body member, and to be connected to a vibration generation part at the proximal end side protruding outwardly from the first main body member; a second main body member connected and fixed to the distal end protruding outwardly from the first main body member in the connection member; and a substantially tubular elastic body placed on the outer circumferential side of the connection member and between the first main body member and the second main body member, and elastically connecting the first main body member and the second main body member, wherein a cavity part through which the connection member penetrates is formed at the central part of the elastic body, and a stopper rubber is located in the cavity part, and the stopper rubber is fixed to the outer circumferential side of the connection member, such that the outer circumferential surface of the stopper rubber faces the inner circumferential surface of the first main body member with a prescribed gap interposed therebetween.
