Vibration isolator

摘要

A vibration isolator which can attain both a reduction in the vibration transmitting power and superior durability of an elastic stopper and which has a compact stopper structure. This vibration isolator comprises an inner member (5); a mounting member (6) having a tubular portion (61) which is disposed outside and at a distance from the inner member approximately coaxially with the inner member; a rubber elastic body (7) disposed between and connecting integrally the inner member and the tubular member and having an axially through cavity portion (71); and an elastic stopper (8) projecting from an inner circumferential surface of the tubular portion in a manner to face the inner member by way of the cavity portion. This tubular portion has side stoppers (65) which are disposed at both the axial ends of a portion where the elastic stopper is formed, in a manner to face the inner member, and which form therebetween a concave portion depressed in a radially outward direction. The elastic stopper has a projection base portion embedded in the concave portion and projecting in a radially outward direction from fore end surfaces of the side stoppers.
