PIEZOELECTRIC DRIVE DEVICE

摘要

A piezoelectric drive device such that the number of kinds of material usable for a driven body is large and control of the speed and forward and reverse movements of the driven body is easy. The drive device comprises a plurality of piezoelectric vibrating bodies (5), a support (1) supporting the vibrating bodies (5) parallel arranged in such a way as to vibrate in the same direction, a connecting member (2) connecting the vibrating portions of the vibrating bodies (5) to one another perpendicularly to the direction of vibration, and a kick member (3) protruding from an intermediate portion of the connecting member (2) in the direction of vibration. The phases of vibration of the vibrating bodies (5) are different from each other so as to cause the kick member (3) to kick.
