出装置。 The rotation axis of the steering system is divided into an input side rotation axis and an output side rotation axis, and a magnetic material is provided on the surface of a cylinder made of a non-magnetic material, or a cylinder member whose cylinder body itself is made of a magnetic material is used for the input side rotation. Fitted onto the shaft and output side rotating shaft,
The rotation shaft of either the input side rotation shaft or the output side rotation shaft and one end of the cylindrical member are coupled via an elastic material, and the other rotation shaft and the other end of the cylindrical member are fixed with screws or the like. the input-side rotation shaft and the output-side rotation shaft are connected via a stopper means that allows relative movement in the rotational direction within a predetermined angular range;
A coil that detects, as a change in inductance, magnetostriction caused by twisting of the cylindrical member due to relative movement in the rotational direction between the input-side rotating shaft and the output-side rotating shaft is surrounded by a certain gap around the cylindrical member. A steering torque detection device characterized in that it is attached to a fixed member.
