Abstract
A steering device includes an electric actuator that applies a steering force to one end side of a steering shaft. The other end side of the steering shaft is provided with a displacement detection part for detecting the movement amount of the steering shaft. Either a detection target or a displacement detection sensor is provided on the steering shaft and the other is provided in a housing so as to output a signal according to a relative position change amount of the detection target with respect to the displacement detection sensor in the direction of the first axis. A first restriction mechanism restricts the relative movement of the detection target and the displacement detection sensor in a radial direction regarding the first axis to limit the change in the relative position in the radial direction of the detection target and the displacement detection sensor.
