Abstract

PURPOSE:To simplify the constitution, by dividing internal and external electrodes each into two and more and by applying AC voltage to each electrode. CONSTITUTION:An ultrasonic drive assembly is constituted by supporting a rotating shaft 5a of a rotator 5 with a bearing 7 of a case 6, bringing an end face of a stator 4 into contact with the rotator 5 and forcibly tightening a spring washer 9 with a bottom lid 10 of the case 6. This stator 4 is provided by deviating each clearance 2c-3d and 3c-3d between internal split electrodes 2a-2b and between split external electrodes 3a-3b to the inner and outer surfaces of a piezoelectric oscillator 1 such as a ceramic oscillator polarized into inside and outside. By applying AC voltage to these internal and external electrodes 2a-3a and 2b-3b, the drive assembly can be rotated in one direction or in the reverse direction.
