ABSTRACT:
In the present invention, a stator consists of a piezoelectric vibrator having divided electrodes on at least one end, alternating current voltage is applied to each of the divided electrodes of one end and one electrode or each of the divided electrodes of the other end of the stator, and a member to be driven is placed on the end or side portion of the stator. The member is reversibly driven by a reversible circumferential progressive wave produced on the end and side portions.
