Abstract
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.
