Abstract
A steering system includes: an operation mechanism that includes an operation member; and a steered mechanism that is not mechanically coupled to the operation mechanism and that steers a wheel on the basis of a steering operation of the operation member. The operation mechanism includes a steering angle sensor that detects a steering angle of the operation member and a steering direction detection unit that detects a steering direction of the operation member. The steering direction detection unit includes a threaded shaft that is rotatable in the steering direction of the operation member, a nut that is screwed to the threaded shaft, a nut guide that causes the nut to move in an axial direction of the threaded shaft in accordance with rotation of the threaded shaft, and a force detection sensor that detects a force that the nut guide receives from the nut.
