とするトルク検出装置。 Detecting changes in the magnetic properties of the shaft to be measured in a region on the circumferential surface of the shaft to be measured, where the magnetic properties change more than other parts when torque is applied to the shaft to be measured. Torque detection, in which a change in the magnetic properties of the shaft to be measured is detected when a torque is applied to the shaft to be measured, is detected by the detection coil in the region. In the device, a compensation coil separate from the detection coil is provided near the region of the axis to be measured, and when the ambient temperature changes during detection by the detection coil, the detection value of the detection coil is changed. A torque detection device characterized in that a generated error is compensated by a change in the detection value of the compensation coil.
