    摘要： A torque sensor which includes two cylinders fixed to two shafts connected with each other through a torsion bar. The magnetic coupling state of the two cylinders is made variable corresponding to relative rotations of the two shafts. The magnetic coupling state thereof is detected, which is indicative of a torque acting on the shafts. The two cylinders form at the opposite end edges thereof teeth provided with cutouts disposed circumferentially of the cylinders and are opposite to each other at portions of about half a width of each tooth. The two shafts are regulated by rotation so as to not put the teeth of the cylinders completely opposite or non-opposite to each other. This enlarges a rate of change in the magnetic coupling state, detecting the torque with high sensitivity, and reducing a lateral difference in the output.

    摘要： A torque sensor according to this invention is so constructed that a plurality of magnetic cylinders mounted respectively to two shafts coupled via a torsion bar are able to be electromagnetically coupled variably to each other in accordance with the relative rotation of the two shafts, and the electromagnetic coupling state of a plurality of cylinders mounted to these two shafts is detected by the electromagnetic coupling detection coils. Components with elastic properties are used in the construction of the sensor so as to absorb the rattlings and thereby reduce the noise previously associated with these devices.
