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.

An electric power steering device includes a steering column in which a steering shaft for transmitting a steering torque is built, an electric motor for transmitting a steering assist force through a gear mechanism in a gearbox to the steering shaft, and a control device for driving and controlling the electric motor. The control device includes a drive circuit module having a switching element for driving the electric motor, and a control module that is mounted on the gearbox for controlling the drive circuit module. The drive circuit module is mounted on a housing of the electric motor.
