In a vibration wave linear motor, a vibrator stably operates with a simple and small configuration. Both ends of a movable guide member are held by shaft bearing long holes to freely oscillate, and an angle of an inclination phi occurs according to the move of the vibrator. An inner wall of an erecting part of a supporting part also serves as a stopper, and regulates the move of the vibrator in a position where the inclination of the movable guide member becomes theta>phi at the maximum. As a result, the inclination of the movable guide member is always kept to be within the range of theta>phi. A problem that the inclining movable guide member contacts a portion other than a driving contacting part is prevented.
