Abstract
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.
