ABSTRACT:
The present invention comprises a first vibrator comprising a piezoelectric unit and at least one driving contacting part which vibrates by applying a predetermined voltage thereto, a second vibrator which comprises a piezoelectric unit and a plurality of driving contacting parts which vibrate by applying a predetermined voltage thereto, a pressing component which relatively presses the opposing parts of both the first vibrator and the second vibrator, and a driven component which is sandwiched between the first and second vibrators, in contact with the driving contacting part of the first and second vibrators which are pressed by the pressing component, and supported to enable movement with respect to the first and second vibrators in the long-side direction perpendicular to the direction relative to the opposing part.
