ABSTRACT:
A torque transducer including a ferromagneto-stricting device provided for a rotational shaft, a magnetic field supply device for supplying a magnetic field to the ferromagneto-stricting device, a sensing device for sensing a change in the magnetic permeability of the ferromagneto-stricting device caused by torque applied to the rotational shaft, a fixed housing for rotatably supporting the rotational shaft, an electromagnetic shielding device for electrically shielding the magnetic field supply device and the sensing device, and a spacer interposed between the fixed housing and the electromagnetic shielding device for causing the electromagnetic shielding device to be held in the fixed housing.
