TORQUE SENSOR, AND VEHICLE STEERING DEVICE

To accurately correct a linearity error in a detection value from a magnet type torque sensor.SOLUTION: A torque sensor 1 comprises a storage unit 47c that stores a correction map indicating the relationship between a correction value and a detection value output from a magnetic detection element 47a. When the variation width between a first detection value Tdmax when the relative rotational amount in a first direction between an input shaft 82a and an output shaft 82b reaches the maximum permissible amount, and a second detection value Tdmin when the relative rotational amount in a second direction reaches the maximum permissible amount, is equally divided into four areas, which are defined as a first area R1 to a fourth area R4 in the ascending order from the smallest area, more correction points are set in the first area R1 and the fourth area R4 than the second area R2 and the third area R3.SELECTED DRAWING: Figure 13 【課題】磁石式トルクセンサの検出値の直線性誤差を精度良く補正する。【解決手段】トルクセンサ１は、磁気検出素子４７ａが出力する検出値と補正値との間の関係を示す補正マップを記憶した記憶部４７ｃを備える。入力軸８２ａと出力軸８２ｂとの間の第１方向の相対回転量が最大許容量に達したときの第１検出値Ｔｄｍａｘと、第２方向の相対回転量が最大許容量に達したときの第２検出値Ｔｄｍｉｎと、の間の変化幅を４つの領域に等分し、検出値の大小順に小さい順に第１領域Ｒ１～第４領域Ｒ４と定義した場合に、第２領域Ｒ２及び第３領域Ｒ３よりも第１領域Ｒ１及び第４領域Ｒ４に多くの補正点が設定されている。【選択図】図１３
