PROBLEM TO BE SOLVED: To provide a multi-degree-of-freedom active vibration damping device enlarging the maximum vibrating damping force and maximum vibration damping torque applicable to a vibration damping object. SOLUTION: The device for damping vibration by applying triaxial vibration damping force and vibration damping torque offsetting three degrees of freedom of linear vibration and rotational vibration generated to the vibration damping object, is equipped with: a base plate mounted to the vibration damping object; six linear motion links expansible in predetermined directions respectively with one ends fixed in a displacement restricted manner to the base plate; a movable mass supported in a displacement restricted manner to the other end of each linear motion link; a displacement detecting means for detecting the amount of expansion of each linear motion link; a vibration detecting means for detecting vibration components generated to the vibration damping object; and a control means for controlling the expansion operation of each linear link according to the amount of expansion detected by the displacement detecting means and the vibration components detected by the vibration detecting means. Fixed points of the respective linear motion links to the base plate and the movable mass are arranged to reduce a distance between the base plate and the movable mass.
