An active vibration isolation support system, supplies current to a coil of an actuator according to the vibrational state of an engine, so that the actuator moves out and back a movable member to which an elastic body is connected. The elastic body is then deformed to change the capacity of a liquid chamber, thereby exerting vibration isolation function. Even if the pressure in a sealed internal space of an actuator case is changed due to the moving out and back of the movable member, the current is variably supplied to the coil of the actuator according to such a change in the pressure of the internal space, thereby controlling the thrust of the movable member so as to be constant. Therefore, the movable member is appropriately driven without receiving the influence of the change of the pressure in the sealed internal space of the actuator case, thereby exerting full performance of the active vibration isolation support system.
