PROBLEM TO BE SOLVED: To provide a twisting device of a rotating shaft for a magnetostrictive torque sensor capable of suppressing torque fluctuation even when heat is applied to the rotating shaft.;SOLUTION: In this twisting device 10 of the rotating shaft for the magnetostrictive torque sensor for twisting the rotating shaft 11 on which a magnetostrictive film 17 is formed with a prescribed torque by a torque generation means 16, a torsion bar 14 is interposed between the rotating shaft 11 and the torque generation means 16. A rotation angle of the torque generation means becomes a total of an angle of torsion of the rotating shaft and an angle of torsion of the torsion bar by interposing the torsion bar. If the rotation angle is large, an influence of an angle change caused by irregularities becomes small, and resultantly the torque fluctuation is mitigated and the torque fluctuation can be suppressed.;COPYRIGHT: (C)2008,JPO&INPIT
