Abstract
A rotational angle detector for detecting the rotational angle of the rotor in a wide range without requiring dark current. A first detection gear including an m number of teeth and a second detection gear including an L number of teeth are each engaged with a main gear rotated integrally with a steering shaft which includes an n number of teeth. A microcomputer calculates a rotational angle θ of the steering shaft using a rotational angle α of the first detection gear within one cycle and a rotational angle β of the second detection gear within one cycle.
