摘要： A vibrator of a vibration wave linear motor comprises two and one driving contacting parts respectively on top and bottom surfaces. A first guide member contacts the two driving contacting parts on the top surface, and both ends of a second guide member are pressed upward by spiral springs, and pressing forces are applied respectively between the driving contacting parts and the first and the second guide members. The three driving contacting parts convert elliptical vibrations, which are generated by applying a voltage to a vibrator unit, into driving force, whereby the vibrator self-runs in a direction indicated by a bidirectional arrow d with reference to the first and the second guide members. the self-running of the vibrator is conveyed, via a pin member and an engaging protruding part, to the lens frame, which then slides.

摘要： In a vibration wave linear motor, a coupled driving contacting parts are respectively provided on the top and the bottom of a vibrator unit, and 2 upper and lower guide shafts which contact concave parts of the coupled driving contacting parts are supported by erecting parts of a supporting part. The lower guide shaft is pressed upward by spiral springs, so that the two guide shafts press and sandwich the vibrator. Alternating current voltages having different phases are applied to the vibrator unit, whereby the vibrator unit generates a vibration wave to generate elliptical rotation vibrations in the driving contacting parts. As a result, the vibrator, and the two guide shafts and the supporting part make a relative move in the shaft direction. Either the guide shafts or the vibrator is fixed, and the other is linked to an object to be driven.

摘要： 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.

摘要： A vibration wave linear motor comprises a vibrator unit having two driving contacting parts which are respectively formed on top and bottom surfaces of the vibrator unit, two guide members guiding the running of the vibrator unit by sandwiching the vibrator unit in parallel with the running direction. The upper guide member is fixed to the supporting member. The lower guide member is held in shaft bearing long holes, pressed upward by coil springs within hollow convex parts. The vibrator unit self-runs and moves forward and backward between the two guide members with an ultrasonic vibration. A linking pin fixed on the side surface of the vibrator unit engages with the member to be driven, so that moving force is transmitted.
