Abstract
A torque detecting device has a measuring shaft, an excitation device and a detector for detecting a magnetostriction passing through said measuring shaft. The device is able to measure the torque with accuracy even if a temperature gradient is produced in the axial direction of the measuring shaft by making the measuring shaft from a material having specified electromagnetic characteristics at least in a part in which said magnetostrictive force is detected.
