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 φ 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 θ>φ at the maximum. As a result, the inclination of the movable guide member is always kept to be within the range of θ>φ. A problem that the inclining movable guide member contacts a portion other than a driving contacting part is prevented.
