A torque sensor is configured so that a multi-pole permanent magnet is fixed to one of a first shaft and a second shaft linked via a torsion bar, a first rotating yoke and a second rotating yoke each having provided at equal intervals in the peripheral direction a plurality of claw portions facing the permanent magnet are fixed to the other of the first shaft and second shaft, and a magnetism detection element is disposed between a first magnetism-collecting yoke and a second magnetism-collecting yoke individually facing the first and second rotating yokes. The first and second rotating yokes are formed into identical shapes, and the claw portions provided respectively on the rotating yokes are alternatingly disposed in the peripheral direction within the same plane perpendicular to the axes of the first shaft and second shaft. Accordingly, it is possible to reduce a cost by having fewer types of parts. |
