Abstract
In a torque sensor that detects torque acting on a torsion bar in accordance with the density of magnetic flux guided to a rotating magnetic circuit portion from a magnetism generating portion, the magnetism generating portion includes a back yoke that rotates together with a first shaft, a ring magnet joined to the back yoke, and an adhesive that is interposed between the back yoke and the ring magnet to join the two, and the adhesive includes a rotation-stopping projecting portion that engages with a rotation-stopping recess portion formed in the back yoke to function as a latch for stopping relative rotation between the back yoke and the ring magnet when an adhesion portion thereof adhered to the back yoke peels away.
