PROBLEM TO BE SOLVED: To provide a vibration isolator of high fatigue strength, in which an integral molding is easily press-fitted into an outer cylindrical body without removing a thin portion after vulcanization integral molding of a rubber elastic body. SOLUTION: An outer cylindrical body 11 is provided with a raised portion 14 raised in the circumferential direction near a center of an inner peripheral face, a recessed portion 15 recessed continuously from each axial end portion of the raised portion 14, and an outer end wall portion 16 raised in the circumferential direction from a bottom portion of the recessed portion 15. The rubber elastic body 12 is provided with a press-fitting portion 17 raised so that it has an outer diameter larger than an inner peripheral face of the outer cylindrical body 11, and a thin portion 20 continued to each axial end portion of the press-fitting portion 17, having an outer diameter smaller than an inner diameter D4 of the outer end wall portion 16, and extending to an axial outer side with respect to the outer end wall portion 16. The thin portion 20 has the taper shape gradually thinned toward the axial outer side in a state that the rubber elastic body 12 vulcanized and integrally molded to the inner cylindrical body 10 is press fit to the outer cylindrical body 11.
