Abstract
A shaft having a magnetostrictive sensor measures torque applied to a shaft, as a shaft, without contact and utilizing reverse-magnetostrictive properties of magnetic alloys. The shaft includes a plurality of magnetic alloy layers, and the magnetosensitive torque detector is variously formed by diffusion bonding a magnetostrictive layer with a high magnetostrictive constant onto the shaft surface, by heat treating, adhesive fixation or the like bonding means. Methods for making the shaft are disclosed.
