PROBLEM TO BE SOLVED: To provide a liquid-sealed vibration isolator simplified in structure, enabling to selectively switch a plurality of orifices. SOLUTION: The vibration isolator is structured to switch the only flow path of a first orifice 21 between a connecting condition and a disconnecting condition by rotatively inserting a rotor 51 into the flow path of the first orifice 21 and rotating the rotor 51. Since it is unnecessary to arrange two flow paths in complicated routes such as crossing the two orifices like a conventional one wherein the two flow paths are switched by one rotor, routes of the first orifice 21 and a second orifice 22 can be simplified. Structure of a partition 20 as the whole can be thereby simplified, and the manufacturing cost can be reduced. Further, since air draining performance is improved, stay of air inside of each route when assembling under the liquid can be restricted to improve dynamic characteristic and reliability.
