Abstract
A device for detecting a rotating speed of a wheel of a vehicle, including an axle hub having a shaft portion, and a flange portion which extends radially outwardly from one of opposite ends of the shaft portion such that the wheel is secured to the flange portion. The shaft portion has an intermediate section at which the axle hub is rotatably supported by a stationary member via a bearing. The detecting device further includes a rotor secured to a part of the shaft portion of the axle hub remote from the flange portion so that the rotor is rotatable with the wheel. The rotor has an externally toothed section which has a multiplicity of teeth spaced apart from each other in a circumferential direction of the rotor. A speed detector is supported by the stationary member, so as to detect the teeth of the toothed section of the rotor during rotation of the rotor. A covering member attached to the stationary member cooperates with the same to cover the rotor.
