PROBLEM TO BE SOLVED: To provide a liquid sealing type vibration isolator elongating a durable life of a coating part comprising a rubber elastic body and the like provided in a stopper means. SOLUTION: A base isolation base body 3 comprising the rubber elastic body is interposed between an inner cylinder 1 and an outer cylinder 2, and a pair of liquid chambers 4 positioned in the both sides of the inner cylinder is provided between the inner cylinder 1 and the outer cylinder 2 deformably by the relative displacement of the inner cylinder 1 and the outer cylinder 2. An orifice 5 communicating the both liquid chambers 1 and 2 is formed, a stopper means 6 suppressing the relative displacement between the inner cylinder 1 and the outer cylinder 2 to a prescribed range is provided, and the stopper means is so constituted that a spherical stopper part 11 and a stopper object part 12 recessed into a partially spherical shape are dividedly disposed in the side of the inner cylinder 1 and the side of the outer cylinder 2.
