Abstract
An ultrasonic motor, which drives a driven member using an elliptical vibration produced by synthesizing a longitudinal vibrational mode and a flexural vibrational mode as a drive force, is configured as follows. Namely, the ultrasonic motor includes a piezoelectric device, and a feed member feeding the piezoelectric device. An extensional axis of the feed member is set to an axis different from main vibrational axes of the longitudinal vibrational mode and the flexural vibrational mode.
