PURPOSE:To lessen the dispersion of vibration absorbing characteristics by communicating a working chamber which is filled with fluid, with a compensation chamber through a throttling passage, and thereby coupling a movable ring which can be moved in the radial direction, into a disc shaped limit stopper within the working chamber. CONSTITUTION:An engine mount is made up out of a working chamber 15 and of a compensation chamber 16, wherein both of the chambers are mutually connected through a throttling passage 3 while they are filled with incompressible fluid. A limit stopper 23 is connected to the lower end of a support 10, so that a movable ring 24 made of elastic material such as rubber and the like is coupled therein. The movable ring 24 is almost closely fitted in the working chamber 15 via 4 projections disposed at its outer circumference. Vibration is absorbed because the movable ring 24 slides against the limit stopper 23 in the radial direction even if there is dispersion in installing the engine mount. This thereby allows the interval spaced from the inner wall of the working chamber to be kept constant, the dispersion of vibration absorbing characteristics is therefore lessened. |
