Steering device

A steering device comprising:

• a housing including a housing body part, a steering shaft housing space, and a first restriction mechanism housing space, with the steering shaft housing space being provided inside the housing body part, and the first restriction mechanism housing space being provided in the housing body part and connected to the steering shaft housing space;
• a steering shaft having a bar shape, which, referring an axis which passes through a center of the steering shaft in a cross section perpendicular to a longitudinal direction of the steering shaft and is parallel to the longitudinal direction of the steering shaft as a first axis, is disposed inside the steering shaft housing space and moves in a direction of the first axis to allow steering of a steering wheel;
• a detection target, which, referring either the housing or the steering shaft as a first member and another as a second member, is attached to the first member;
• a displacement detection sensor attached to the second member and capable of outputting 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 provided in the first restriction mechanism housing space and restricting a relative movement of the detection target and the displacement detection sensor in a radial direction regarding the first axis, and
• an electric actuator for applying a steering force to the steering shaft based on an output signal of the displacement detection sensor.
