Kind Code:
A1
Abstract:
The present invention achieves weight reduction and suitably prevents an outer cylinder from being damaged when the outer cylinder is installed on an attachment member. The present invention comprises an inner cylinder (11), a resin outer cylinder (12) that is arranged on the radial-direction outside of the inner cylinder (11), and a rubber elastic body (13) that connects the inner cylinder (11) and the outer cylinder (12). The outer cylinder (12) comprises: a press-fitting part that is press-fitted into an insertion hole (51) that is formed in an attachment member (50); and a taper part (15) that is continuous with the press-fitting part and extends in the direction in which the press-fitting part is inserted into the attachment member (50). The taper part (15) is tapered so as to decrease in diameter in the press-fitting direction. An outer surface (15a) of the taper part (15) is formed to be parallel to a tapered guide surface (54) that is provided at an insertion opening (53) of the insertion hole (51) of the attachment member (50).
