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. A detection coil is attached to each of the legs of the other pair to serve as an excitation pole and a detection pole, and the tip of each leg is placed opposite to the outer circumferential surface of a rotating shaft for power transmission made of a magnetic material with a gap therebetween, thereby causing the rotation. In a torque detection device that detects torque applied to a shaft,
The ferrite magnetic core equipped with the excitation coil and detection coil is molded in resin, and a hole is drilled from the side of the resin in a direction substantially perpendicular to the direction of the legs in the molded resin portion between the excitation pole and detection pole. 1. A torque detection device comprising a magnetic adjustment means comprising a hole and a magnetic core inserted into the hole.
