Claims

[Claims for Utility Model Registration] (1) Among the magnetic legs of a magnetic core having magnetic legs erected at each apex corner of a substantially quadrilateral, a pair of magnetic legs in a diagonal relationship,
An excitation leg and a detection leg are respectively used, and the end faces of the excitation leg and the detection leg are opposed to the surface of a torque transmission shaft with a gap between them, and the torque is transmitted from a change in the induced voltage generated in a coil wound around the detection leg. In a torque detection device that detects the torque of a shaft, a rotating body in which a magnetic body is attached biased from the center of rotation in each of two planes defined by a diagonal line connecting a pair of diagonal magnetic legs. A torque detection device characterized by being rotatably mounted. (2) The torque detection device according to claim 1, wherein the magnetic body has an opening angle of approximately 90° from the rotation axis.
