摘要： An ultrasonic motor including a driving member and a driven member, the driving member comprising a plate- or rod-like elastic member, a flexural vibrator fixed to the elastic member and causing the elastic member to induce a standing wave type flexural vibration upon application of an AC voltage thereto, and a longitudinal vibrator provided on a node line of the flexural vibration at the surface of the elastic member, the longitudinal vibrator being pivoted about the node line by the flexural vibrator and adapted to expand and contract in an amplitude direction of the flexural vibration upon application of an AC voltage thereto, the driven member being brought into pressure contact with an end face of the longitudinal vibrator. The longitudinal vibrator is expanded or contracted in synchronism with the flexural vibration, whereby the driving member and the driven member are moved relatively to each other.
