Claims

[Scope of utility model registration request]

(1) A high magnetostrictive metal having high magnetostrictive properties that is wound around the surface of a rotating shaft that generates torque; an input coil that is wound non-contact around this high magnetostrictive metal and inputs an input signal to the high magnetostrictive metal; and a torque sensor comprising an output coil that is wound in a non-contact manner around the high magnetostrictive metal and electrically detects a change in the relative magnetic permeability of the high magnetostrictive metal as torque is generated on the rotating shaft, A torque sensor characterized in that the input coil and the output coil are arranged at a predetermined interval.

(2) The torque sensor according to Claim 1 of the utility model registration, characterized in that the input coil and the output coil are arranged at a predetermined interval in the direction of the rotation axis. The torque sensor according to claim 1', characterized in that the torque sensor is arranged at predetermined intervals in the radial direction.
