Abstract
A built-in wheel speed sensor structure having an internal gear-like sensor rotor integrally fixed to a tire and an electromagnetic car speed sensor fitted to an inner portion of a parking brake and facing the sensor rotor. The wheel speed sensor is supported by an anchor pin of the drum brake so that the sensor rotor may be positioned away from service holes for fastening bolts which have been bored into a brake drum.
