Abstract
An ultrasonic linear motor of the present invention comprises an ultrasonic vibrator which has an electromechanical energy converting element and presses a driven member to produce a driving force for driving the driven member, a pair of pressing members which are arranged so as to sandwich the vibrator and exert a pressing force on the driven member at the positions corresponding to nodes of a standing wave on the vibrator, a support member which pivotally supports the pressing members, and an elastic member which exerts simultaneously on the pair of pressing members a deflecting force serving as a pressing force to the driven member.
