PROBLEM TO BE SOLVED: To provide an active type vibration-proof device capable of realizing control of an actuator without detecting a voltage applied to the actuator.SOLUTION: An active type vibration-proof device 6 of this invention comprises ab rod main body 63 having a pair of elastic connectors 61, 62 at both ends to connect the pair of elastic connectors; an inertia mass 641 supported at the rod main body; an actuator 64 including a magnetic force generating means for reciprocating the inertia mass in an axial direction of the rod main body; a current detecting means 68 for detecting a value of current flowing in the magnetic force generating means; and a control means 65 for controlling the actuator in such a way that a force corresponding to a displacement speed of the rod main body in an axial direction C may be generated in the mass. The control means includes a state estimating means for calculating a control signal for the actuator with an electric current detected by the current detecting means being applied as a measured amount.SELECTED DRAWING: Figure 2
