摘要： A driving device includes a piezoelectric element that expands and contracts by the application of voltage, a driving shaft fixed to one end of the piezoelectric element in a direction of the optical axis, a lens holder fixed to the other end of the piezoelectric element in the direction of the optical axis, a friction portion frictionally engaged with the driving shaft, and a base that supports the driving shaft such that the driving shaft is capable of moving along the optical axis. The friction portion includes a receiving portion and a leaf spring that are arranged in a manner such that the driving shaft extending along the optical axis is clamped therebetween in the radial direction.
摘要翻译：驱动装置包括通过施加电压而膨胀和收缩的压电元件，沿着光轴的方向固定在压电元件的一端的驱动轴，固定在压电元件的另一端的透镜保持架光轴的方向，与驱动轴摩擦接合的摩擦部，以及支撑驱动轴的基座，使得驱动轴能够沿着光轴移动。摩擦部包括以沿着光轴延伸的驱动轴在径向夹持的方式配置的接收部和片簧。
