PROBLEM TO BE SOLVED: To provide an active liquid-sealed vibration control device restricting the displacement of a movable shaft of an actuator. SOLUTION: This vibration control device is so configured that a vibration plate 18 forming a part of the chamber wall of a first liquid chamber 16 is vibrated and driven by the actuator 20. The vibration control device is provided with a stopper means 66 restricting the displacement of the movable shaft 48 of the actuator in an axial direction X. The stopper means 66 is composed of a part to be stopped 68 projecting outward Y1 in a direction perpendicular to a shaft in a shaft member 72 as a joint with respect to a diaphragm 22 in the movable shaft 48, and a stopper part 70 provided to a stopper member 76 fixed on a second fixture 12 and restricting displacement by abutting the part to be stopped 68 by the displacement of the movable shaft 48 in the axial direction X.
