Abstract
A linear drive ultrasonic motor includes at least an ultrasonic vibrator having a piezoelectric element, a driven member which is driven relatively by a frictional force between the ultrasonic vibrator and the driven member, a plurality of coupling members which are coupled with the driven member, a frame body which is coupled with the coupling member, a bias applying member which applies a bias to the driven member by the ultrasonic vibrator, a base member which movably supports the driven member, and a rolling member having a spherical shape which movably supports the driven member with respect to the base member. The plurality of coupling members include a positioning portion which determines a position of the respective frame body, and which have a shape which enables to fix by a point contact, sandwiching the frame body.
