Abstract
An actuator, a stator, a motor, a rotational-to-linear motion conversion mechanism, and a linear actuator are provided. The motor, the actuator, and the linear actuator at least include a screw shaft and a nut. The screw shaft is a rod-like member, and at least a part of the surface of the screw shaft has a thread. The nut is screwed onto the thread on the screw shaft, and moves the screw shaft in a linear motion direction that is a direction in parallel with a rotational center. The stator, the motor, the actuator, and the linear actuator can at least convert a rotational motion into a linear motion.
