ABSTRACT:
A change in a magnetic resistance generated between a plurality of windows of a cylindrical member formed by a nonmagnetic material and a torsion bar is regarded to be a change in inductances of detecting coils to detect a steering torque. Coil yokes accommodating the detecting coils therein are disposed coaxially on an outer periphery of the cylindrical member and L-shaped bent tip portions of output terminals of the detecting coils are inserted into a hole of a circuit board of a control module. Terminal holding portions are provided on an inside of a moving track so that an interference with other components can be prevented. The circuit board of the control module is disposed perpendicularly to a direction of shaft centers of an input and output shafts. An output terminal of a detecting coil has a tip portion bent to take an L shape and formed perpendicularly to the hole of the circuit board. Therefore, the detecting coil and the control module can be directly connected. When a gear box mounting the control module thereon is to be disposed in a small engine room, space efficiency can be increased and a shock absorbing stroke of a shock absorbing mechanism can be maintained sufficiently.
