Abstract
The invention provides an ultrasonic driving apparatus in which an oscillator contained therein is pressed against a driven member and can be positioned with a high degree of precision. The invention includes an oscillator for generating vibrations when supplied with electrical power; a holding member fixed to the oscillator; an urging member for urging the oscillator in a predetermined direction; and a support member for supporting the holding member so as to be capable of moving in the predetermined direction, wherein positioning portions for setting, with a certain degree of precision, the position of the oscillator which is projected onto a plane substantially orthogonal to the predetermined direction are provided in the holding member and the support member.
