A compact vibration reducing apparatus includes a dynamic mass 22; elastic member 23-1 to 23-2, 24-1 to 24-2 which apply elastic force to the dynamic mass 22 so that the dynamic mass 22 vibrates in a parallel to a vibration damping direction 25; a control mass 26; an actuator 27 which move in parallel to a length change direction 34; and a motion direction converting mechanism 28 which moves the control mass 26 to the dynamic mass 22 so that the control mass 26 moves in a vibration damping direction 25 to the dynamic mass 22 through the operation of the actuator 27. The actuator 27 is supported by the dynamic mass 22 so that the operation direction 34 of the actuator 27 is not parallel to the vibration damping direction 25. Therefore, such a vibration damping unit 19-i can be made more compact in the vibration damping direction 25, compared with another vibration reducing apparatus in which the operation direction and the vibration damping direction are same.
