Abstract:
A magnetostrictive torque sensor includes a magnetostrictive portion formed on a rotational shaft, a bobbin surrounding an outer circumference of the magnetostrictive portion, and a coil wound on the bobbin for detecting a change in magnetic property of the magnetostrictive portion. The bobbin fits over the magnetostrictive portion in contact with the magnetostrictive portion in such a manner as to allow rotation of the magnetostrictive portion relative to the bobbin. The magnetostrictive torque sensor is carried on an electrically assisted bicycle or an electric power steering apparatus of a vehicle.
