    • An actuator in which, when a supporting shaft, where a mirror (control object) is provided, is tilted by receiving an electromagnetic force of a magnetic driving mechanism, small balls of a supporting mechanism move in an axial direction in a space provided between an outer base and an inner ring member. Therefore, the supporting shaft and the inner ring member holding the supporting shaft swing. At this time, since the inner ring member swings around a rotational fulcrum as center, the supporting shaft can swing around one rotational fulcrum as center at all times. A plurality of laid members serving as a rotation restricting member prevent rotation of the supporting shaft in a direction around the axis.
    • 一种致动器,其中当设置有反射镜(控制对象)的支撑轴通过接收磁驱动机构的电磁力而倾斜时,支撑机构的小球在轴向方向上在设置在 外底座和内圈构件。 因此,支撑轴和保持支撑轴的内圈构件摆动。 此时,由于内圈构件围绕作为中心的旋转支点摆动,所以支撑轴可以一直围绕作为中心的一个旋转支点摆动。 作为旋转限制构件的多个铺设构件防止支撑轴沿着轴线的方向旋转。
