Abstract
An orifice plate 20 is projectingly provided within a fluid chamber formed inside an elastic block to damp the medium to high frequency vibrations. The orifice plate 20 is arranged to have a projection area which is maximum in the principal input direction Z of vibrations to be isolated, medium in the direction Y of the two input directions X and Y which are perpendicular to the direction Z, and minimum in the direction X by providing a recess 26 at a bottom thereof which traverses in the same direction (as the direction X), whereby the resonance frequency is high in the direction Y and the circumferential edge portions of the projection surface in the direction Y are adapted to serve as stoppers 25 which perform the displacement control in the direction X.
