PROBLEM TO BE SOLVED: To accurately determine deterioration of an elastic body of an active vibration control supporting device by secular change or the like. SOLUTION: This active vibration control supporting device M drives a movable core 54 by conducting electricity into a coil 46 of an actuator 41, and a second elastic body 27 partitioning a part of a second liquid chamber 31 is reciprocated to suppress transmission of vibration of an engine to a vehicle body frame. When the second elastic body 27 is deteriorated and air gap g of the movable core 54 is increased or decreased, it is determined that the second elastic body 27 is deteriorated when deviation of real current and target current exceeds a threshold value by focusing on change of inductance of the coil 46, change of real current, and non-agreement of real current and target current. When deterioration of the second elastic body 27 is determined, target current is compensated in accordance with the deviation to ensure a damping function of the active vibration control supporting device M.
