ACTUATOR UNIT

摘要

An actuator unit is constituted of a movable body (30'), a movable mechanism (8) for moving the movable body (30'), a flat stepping motor (50) as the drive source of the movable mechanism (8), and a supporting body (10) for fixing them. A pair of yoke plates (21, 21) of the flat stepping motor is fixed so as to sandwich portion of a supporting body (10'). The portion of the supporting body sandwiched by the yoke plates serves as a spacer section (51). As a result, the distance between the pair of the yoke plates can be set in an excellent accuracy by the thickness of the spacer section.
