ABSTRACT:
The distal end of a flange of a stator serving as a contact member is located on the outer peripheral side of one linear portion of an elastic member serving as a vibration member, and the inner peripheral side of this linear portion of the elastic member is located on the proximal side of the flange. The ratio of the response amplitude of the flange of the stator to the amplitude of the elastic member is kept almost constant in all areas of contact portions between the two members.
