Abstract

PURPOSE: To make attachment to a door easy with a simple structure, and miniaturize and thin the device, and also obtain a high driving torque by employing an ultrasonic wave motor of a traveling-wave type, a torisonal connector type or the like as a driving source. CONSTITUTION: A desk type traveling-wave supersonic wave motor is formed by combining a stator part 7 comprising two sheets of piezoelectric ceramics 1 being phase-shifted at 90 degrees and an elastic body such as stainless and a rotor part 8 comprising a rotation body 3 and lining material 4 by a nut 6 with adaptive pressure. Then, the stator part 7 is secured to the lower part of a door directly or via an attachment housing; subsequently, a traveling wave is generated by applying alternate voltage being phase-shifted at 90 degrees to the ceramics 1 so as to generate traveling wave, so that the rotating body 3 rotates through backward vibrations generated at the elastic body 2 in order to permit the door to move via an output shaft of the rotor part 8 extended inside of the door. Besides, an ultrasonic motor of a torsional connector type can be used herein.
