Abstract:
1. A magnetostrictive mechanical quantity sensor for detecting a torque or an axial force, comprising: an operating shaft upon which the torque or the axial force acts from an external origin; a hollow shaft having a first magnetostrictive film formed on an outer perimeter surface, the hollow shaft including at least one pin hole defined therethrough; and at least one fitting-flange part encircling the operating shaft, the at least one fitting-flange part having a pair of pin holes passing therethrough in a direction orthogonal relative to a longitudinal axis of the operating shaft at a location corresponding to the at least one pin hole defined in the hole shaft, wherein the at least one fitting-flange part is disposed directly between the hollow shaft and the operating shaft, and wherein pins are provided in the pair of pin holes of the at least one fitting-flange part and the at least one pin hole defined through the hollow shaft linking the operating shaft to the hollow shaft.
