The magnetic head of a magnetostriction torque sensor is covered by a magnetic head holder made of a synthetic resin and supported by an outer tubular member via an elastic supporting member. The magnetic head holder is formed with bearing portions by which an axle to be measured is rotatably supported in such a way that a predetermined clearance is always kept at a constant value between the magnetic head and the axle. Therefore, even if the axle to be measured or the outer tubular member to support the magnetic head deforms or if the concentricity of the outer tubular member with respect to the axle is inferior, it is possible to stably and precisely detect the torque applied to the axle to be measured. The above-mentioned structure of the magnetostriction torque sensor can reduce the manufacturing cost and improve the productivity. |
