PROBLEM TO BE SOLVED: To provide a vibration exciter for active vibration control of a new structure capable of controlling frequency of generated excitation force easily and in high precision and capable of stably providing the large excitation force. SOLUTION: Magnetic pole parts 42a, 42b of a yoke member 12 and magnetic suction parts 44, 46 of an excitation member 14 are inclined in the axial direction and opposedly positioned in the diametrical direction, and ring edge parts 29, 36, 48, 50 are formed on each of proximity side end parts of these magnetic pole parts 42a, 42b and magnetic suction parts 44, 46. |
