Abstract
A stator consists of a cylindrical piezoelectric vibrator and electrodes respectively divided in two in its inside and outside portions. When alternative current voltage is applied to respective one of divided electrodes in the inside and outside portions, reversible progressive waves generate on the end and side portions of the stator. When a rotary member is combined with the end or side portion of the stator, the rotary member can reversibly be moved.
