PROBLEM TO BE SOLVED: To enhance the vibration control effect by reshaping a vibration waveform of an elastic body connected to a movable member of an active vibration control support device. SOLUTION: The movable member 20 is vertically movably supported by the elastic body 18, and is opposed downward to a magnet 46 fixed to an under surface of an orifice forming member 15 of the active vibration control support device M. After moving the elastic body 18 downward from an initial position integrally with the movable member 20 by driving an actuator 29, when releasing driving of the actuator 29, the elastic body 18 tries to return to the initial position by elastic restoring force of itself. In that case, the elastic body 18 quickly returns to the initial position without performing high frequency vibration by generating energizing force for returning the elastic body 18 to the initial position by attracting the movable member 20 upward by the magnet 46, and the vibration control effect can be enhanced by reshaping the vibration waveform of the elastic body 18.
