Abstract: A liquid-sealed vibration prevention device is provided with a main rubber-elastic body for elastically connecting an inner cylinder with an intermediate sleeve, an outer cylinder for sheathing the intermediate sleeve, and a seal rubber layer positioned on the inner-circumferential surface of the outer cylinder. The intermediate sleeve has an upper ring part, and the upper end face of the upper ring part is provided with an inclined projection part which extends diagonally upward toward the inner cylinder. Moreover, a pair of rotation-stop rubbers that holds the inclined projection part in the circumferential direction of the intermediate sleeve is provided on the inner side of an annular recess of the outer cylinder and on the upper part side of the seal rubber layer.

Abstract: A pair of fluid chambers in which incompressible fluid is sealed and a pair of orifice-forming members that allows one fluid chamber to communicate with the other fluid chamber are arranged between an inner cylinder and an outer cylinder. The orifice-forming member has a longitudinal groove that communicates with respective fluid chambers, an orifice channel, and a liquid storage section that allows the longitudinal groove to communicate with the orifice channel. The liquid storage section is formed wider and deeper than the orifice channel.
