センサ。 A magnetic body having a magnetostrictive effect is provided on the outer circumferential surface of the drive shaft, and an excitation coil and a detection coil are coaxially arranged on the outer circumference of this magnetic body to form a magnetic circuit passing through the magnetic body. By fixing a magnetic body to the outer peripheral surface of the drive shaft, the torque is detected using magnetostriction caused by deformation of the magnetic body due to torsional torque applied to the drive shaft. Magnetostrictive torque sensor.
