TORQUE SENSOR

摘要

A torque sensor according to this invention is so constructed that a plurality of magnetic cylinders mounted respectively to two shafts coupled via a torsion bar are able to be electromagnetically coupled variably to each other in accordance with the relative rotation of the two shafts, and the electromagnetic coupling state of a plurality of cylinders mounted to these two shafts is detected by the electromagnetic coupling detection coils wound around the cylindrical members. Since the elastic members are provided on a plurality of cylinders mounted to one of the shafts and/or at least at one side in the axial direction of the two cylindrical members with the cylinders and/or cylindrical members being urged in the axial direction, so that the elastic members absorb the rattling of the cylinders and/or cylindrical members in the axial direction.
