Abstract

A torque detecting device has a measuring shaft and a magnetic circuit incorporating the measuring shaft into a magnetic path which includes a device for detecting a magnet-ostrictive force passing through said measuring shaft. The device is able to increase the output sensitivity, decrease the rotative fluctuation of output and decrease the hysteresis by making the measuring shaft forming the magnetic path from an iron base alloy having a specific composition.
