Abstract
A torque sensor having an improved detection accuracy is disclosed. The torque sensor includes a cylindrical stator. The stator is arranged to face a magnetostrictive member fixed to a shaft. The stator includes a stator body and two retainer rings. When assembling the stator body and the two retainer rings, a pair of exciting coils and a pair of detecting coils are accommodated in the inner wall of the stator. Joints between the stator body and the two retainer rings are not exposed to the inner surface of the stator.
