A liquid-sealed anti-vibration device wherein an annular space is formed between an orifice member and a partition plate member, crimped and fixed downwardly of the orifice member to an anti-vibration device proper, of a partition; and a rubber-like elastic membrane is disposed in the space and has a base portion attached fixedly to the one of the orifice member and the partition plate member and an open terminal at a distal side, the open terminal being slidably in pressure contact with the other, thus constituting a cantilevered sliding membrane structure. Thereby it is possible to diminish the amplitude dependency, to reduce the dynamic spring constant in a wide spectrum of medium and high frequencies, and to lower the noise.
