とを特徴とする、回転トルクセンサ。 In a power transmission system that transmits power from an input shaft on the pinion side to a driven system on the rack side via a rack and pinion, axial displacement is used to detect the axial displacement of the input shaft that occurs in response to the rotation of the input shaft. The detection means detects the input from the axial displacement information sent from the detection means based on the correlation between the rotational torque of the input shaft and the axial displacement of the input shaft accompanying power transmission by rotation of the input shaft. A rotational torque sensor comprising a rotational torque calculation means for calculating rotational torque of a shaft.
