PURPOSE:To eliminate damage of a moving plate by installing a movable member on a prop protruding in a liquid chamber with capability of relative movement perpendicular to the vibrating direction as well as possibility of relative micro-movement in the vibrating direction. CONSTITUTION:A spacer 46 is installed on a prop 24 protruding in a liquid chamber 38, and moving plates 52, 54 are inserted in the periphery. Another moving plate 56 is capable of relative motion horizontally with respect to said plates 52, 54, which has possibility of relative micro-movement in the axial direction of the above-mentioned prop 24. This will prevent damage to movable members even during vibration in different directions. |
