たことを特徴とするトルク検出装置。 An excitation coil is attached to a set of diagonal legs of a table-shaped ferrite magnetic core, each of which has columnar legs erected at the four corners of a substantially rectangular main surface of a flat plate such as a square plate or a circular plate. Detection coils are attached to the legs of the other set to serve as excitation poles and detection poles, and the ends of each leg are placed opposite to the outer circumferential surface of a rotating shaft for power transmission made of a magnetic material with a gap therebetween to rotate the legs. In a torque detection device that detects torque applied to a shaft, the excitation coil, the detection coil, and the attached ferrite magnetic core are molded in resin, and the molded resin part between the excitation pole and the detection pole is provided with the legs. A torque detection device characterized in that it is provided with a magnetic adjustment means consisting of holes arranged in parallel and a magnetic screw core screwed into the holes.
