Abstract

A torque sensor is comprised of a torque detection coil for detecting a torque generated between an input shaft and an output shaft by detecting a change of a relative rotational position between a cover member fixed to the input shaft and a covered member fixed to the output shaft as a change of impedance of a torque detection coil. The cover member is located between the covered member and the torque detection coil and has an outer cylinder portion which extends from an outer periphery of the cover member along a circumferential surface of the covered member.
