Abstract
A neutral position detector detects the neutral position of a steering wheel, and includes a first rotor which rotates integrally with a steering shaft. The first rotor has a slot which is detectable for identifying the steering wheel position. The detector further includes a second rotor which is rotatable interlockingly with the first rotor. A power transmission mechanism is provided to cause the second rotor to rotate intermittently by a predetermined rotation angle, each time the first rotor completes one revolution. The second rotor has a slot for detecting the position of the steering wheel. When the slots of the first and second rotors become aligned, the detector outputs a detection signal indicative of the position of the steering wheel.
