Claim:
A steering system, comprising: an operation mechanism that includes an operation member used to perform a steering operation; and a steered mechanism that is not mechanically coupled to the operation mechanism, and that steers a wheel based on the steering operation of the operation member, wherein 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, and 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, the nut including an insertion hole that passes through the nut in the axial direction, a nut guide that is a shaft member extending in an axial direction of the threaded shaft, the nut guide being arranged parallel to the threaded shaft and passing through the insertion hole, and the nut guide causing the nut to move in the axial direction of the threaded shaft in accordance with rotation of the threaded shaft, and a force detection unit that detects a force that is applied to the nut guide in a circumferential direction of the threaded shaft from the nut.
