PROBLEM TO BE SOLVED: To provide a novel liquid-sealed vibration control device capable of simply and effectively reducing occurrence of striking sound or unpleasant noise caused by contact of the stopper rubber of a stopper with the inner periphery of an outer cylinder. SOLUTION: In this liquid-sealed vibration control device, an inner cylinder 10 is connected to an outer cylinder 12 by a connecting part 14, and transmission of vibration is reduced by the resonance action of liquid sealed within a plurality of liquid chambers 18b communicated with each other via an orifice passage 18a. A stopper 20 for restricting the relative movement of the outer cylinder 10 and the inner cylinder 12 within a prescribed range, is projectedly installed in the diametric direction in the outer periphery of the inner cylinder 10. The tip end of the stopper 20 is covered with stopper rubber 24. Lubricant is applied and adhered in advance to the surface of the stopper rubber 24 contacting with the inner periphery of the outer cylinder 12. With this, the hysteresis width, with the stopper rubber 24 brought in contact with the inner periphery of the outer cylinder 12, is reduced, and in its turn occurrence of striking sound or unpleasant noise can be restricted. |
