摘要： A vibration wave motor includes a housing, a rotor, a bearing member, a vibrator serving as an actuator and having a support shaft and a driving element, and a leaf spring having a pressing protrusion. The vibrator is slidably disposed in an opening of the housing along a rotation axis direction of the rotor, and a support shaft of the vibrator is rotatable. The vibrator is held while being urged by the leaf spring and being in contact with the rotor. The vibrator is excited to generate supersonic vibration so that the rotor is rotated. Since the vibrator is movably supported by the housing in the rotation axis direction and the vibrator is urged by the leaf spring and is in contact with a friction contact surface of the rotor, the vibrator is evenly in contact with the rotor in a direction perpendicular to the friction contact surface so as to provide superior driving conditions of the vibration wave motor.

摘要： A vibration wave motor includes a housing, a rotor, a bearing member, a bending-vibration driving transducer having a support shaft and two driving elements and serving as an actuator, and a leaf spring having a pressing protrusion. The transducer is slidable in an opening of the housing along a rotation axis direction of the rotor, and a support shaft of the transducer is rotatably supported and inserted. The transducer is held while being urged by the leaf spring and being in contact with the rotor. Since the transducer is urged by the pressing protrusion of the leaf spring, the leaf spring is in complete contact with the transducer without edge contact so that the two driving elements are evenly in contact with the rotor in a direction perpendicular to the frictional contact surface, thus providing driving conditions of superior conversion efficiency.
摘要翻译：振动波马达包括壳体，转子，轴承构件，具有支撑轴和两个驱动元件并用作致动器的弯曲振动驱动换能器以及具有按压突起的板簧。换能器沿着转子的旋转轴线方向在壳体的开口中滑动，并且换能器的支撑轴可旋转地支撑并插入。传感器在受到板簧的作用下被保持并与转子接触。由于换能器被片簧的按压突起推动，板簧与换能器完全接触而没有边缘接触，使得两个驱动元件在垂直于摩擦接触表面的方向上与转子均匀地接触，从而提供卓越的转换效率的驾驶条件。
