In a torque sensor that detects torque acting on a torsion bar on the basis of a magnetic flux density conducted to a magnetism collecting ring provided in a housing, the magnetism collecting ring is an annular member formed such that an axial direction end portion thereof is thinner than a central portion. The housing includes an annular groove formed to be capable of accommodating the magnetism collecting ring and provided as a recess in an inner peripheral wall of the housing so as to be deeper than a thickness of the end portion of the magnetism collecting ring, and a caulk portion provided in the inner peripheral wall to caulk the magnetism collecting ring by covering the end portion of the magnetism collecting ring that is fitted into the annular groove. |
