Abstract
To provide a miniaturized actuator. [Solution] The actuator of this disclosure comprises a ball screw device and a transmission component that transmits torque to the ball screw device. The component of the ball screw device that receives torque and performs rotational motion is the rotating component. The transmission component is arranged axially with respect to the rotating component. One end face of the transmission component and the other end face of the rotating component form a pair of opposing faces that face each other in the axial direction. One of the pair of opposing faces is provided with at least one convex portion. The other of the pair of opposing faces is provided with one or more recesses that are recessed in the axial direction and accommodate the convex portion. The convex portion has a first side surface that faces one direction in the rotational direction about the central axis and abuts the first side surface, and a second side surface that faces one direction in the rotational direction and abuts the second side surface.
