Abstract
An ultrasonic motor mechanism includes an ultrasonic vibrator that includes a piezoelectric element; a driven member that is driven relative to the ultrasonic vibrator because of a frictional force generated between the ultrasonic vibrator and the driven member; a coupling member that is coupled to the driven member; a first urging member that urges the ultrasonic vibrator with the driven member; a base member that movably supports the driven member; and a spherical rolling member that movably supports the driven member with respect to the base member. By interposing a second urging member between the driven member and the coupling member, the driven member is urged in a longitudinal direction. The driven member and the coupling member are coupled to each other by causing the driven member to abut the coupling member.
