    摘要: An ultrasonic motor includes a vibrator, a mobile unit, a holding mechanism, and a pressing mechanism. The vibrator generates elliptical vibration by degenerating different vibration modes and having a phase difference between the different vibration modes. The mobile unit is configured to be movable relative to the vibrator. The holding mechanism holds and fixes the vibrator in a direction substantially parallel to the direction of the relative movement of the mobile unit. The pressing mechanism presses the vibrator against the mobile unit. The holding mechanism includes an adjustment unit for adjusting the resonant frequencies of the different vibration modes of the vibrator to substantially match each other when the ultrasonic motor is driven.
