Abstract
A torque sensor includes a first magnet fixed to a first shaft, a tubular magnetic yoke assembly in which a magnetic yoke core is molded with a resin member, and a first magnetic sensor that detects a magnetic flux from the first magnet induced by the magnetic yoke core. The torque sensor also includes a collar made of a ferromagnetic body that is fixed to an inner circumference of the magnetic yoke assembly and to which a second shaft is press-fitted and fixed, and a second magnet for an index sensor that is disposed on an outer circumference of the magnetic yoke assembly. At least a part of the collar is disposed between the magnetic yoke core and the second magnet with respect to an axial direction of the magnetic yoke assembly.
