PROBLEM TO BE SOLVED: To ensure the high tuning freedom of a vibration control characteristic by a plurality of passive hydraulic control systems for passively regulating the pressure of a main liquid chamber on the basis of the displacement or deformation of a movable member so as to be mutually independent by respective movable members. SOLUTION: Upper and lower movable rubber plates 52, 54 passively regulating the pressure of a main liquid chamber 30 by being displaced or deformed by the pressure fluctuation of the main liquid chamber 30 are mutually separately arranged opposite to the wall surface of one air chamber 58. The upper movable rubber plate 52 constitutes a first passive hydraulic control system, and the lower movable rubber plate 54 constitutes a second passive hydraulic control system. The second passive hydraulic control system is formed independently from the first passive hydraulic control system so that the first passive hydraulic control system and the second passive hydraulic control system can be mutually differently tuned. According to this, a wide tuning freedom of vibration control characteristic can be realized. |
