PROBLEM TO BE SOLVED: To provide an active vibration control device of a novel structure, for stably exhibiting objective active vibration control performance over a long period, by exhibiting a stable operation characteristic of a moving piece under superior durability, in the active vibration control device having a solenoid type actuator for generating excitation force by current supply to a coil. SOLUTION: A biased energizing means 148 is arranged for actively energizing the moving piece 112 in the partial loading direction to an inner peripheral surface 138 of a guide hole of a fixed piece 110 by making force turning in one direction of the direction perpendicular to the axis, act between the fixed piece 110 and the moving piece 112 in the actuator 102.
