ABSTRACT:
To obtain stable linear torque-output characteristics over a wide torque range in a magnetostrictive torque detecting apparatus having a shaft to be measured, an exciting coil for magnetically exciting the shaft, and a detecting coil for detecting magnetostrictive components generated in the shaft distorted by a torque, the shaft is particularly composed of a substrate shaft portion made of a high yield point material and a shape anisotropic layer portion made of a high magnetostrictive material metallographically welded on an outer surface of the substrate shaft. The welded shape anisotropic layer portion is formed with two symmetrical groups of concave/convex portions each arranged at regular angular intervals on the outer circumferential surface thereof at an inclination angle with respect to the axial direction of the shaft.
