ABSTRACT:
A device for detecting rotation of a steeering wheel for motor vehicles is disclosed which comprises an encoding member rotatable together with a steering wheel and having markers at predetermined position, a sensor so disposed as to correspond to a locus of rotation of the markers; and a signal generating circuit for generating pulse signals representative of information on the rotation of the encoding member whenever the sensor is caused to correspond to the markers. A first casing housing and rotatably holding the encoding member and a second casing housing and holding the signal generating circuit are formed integrally with each other.
