Abstract
An ultrasonic motor () includes a vibrator () and an application means (oscillation circuit). A first vibrator area () and a second vibrator area (), which form a vibrator (), include piezoelectric elements polarized in the thickness direction, and fixed portions () respectively. The oscillation circuitapplies an AC voltage to the piezoelectric elements respectively and makes the first vibrator area () and the second vibrator area () resonate individually in the surface-spreading directions. The ultrasonic motor () includes a coupling portion () for coupling vibration end portions () each other and a contact element () which is provided on this coupling portion (). The vibration end portions () are positions which vibrate respectively in the approaching and separating directions by the resonances of the first vibrator area () and the second vibrator area () in the surface-spreading directions with respect to the fixed portions ().
