ABSTRACT:
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.
