Abstract
A pulser ring and a pickup sensor are sealingly housed by a seal so as to prevent the penetration of foreign matters. The pulser ring is fixedly mounted on one end face side of an inner ring that is mounted on a drive shaft side to thereby rotate together therewith. The seal has a resilient material mounted at a distal end of a metal ring, and is fixedly mounted on one end face side of an outer ring fixed to a vehicle body side which one end face side corresponds to the one end face side of the inner ring. The seal encompasses the pulser ring inside thereof. The resilient material of the seal is brought into close and slidable contact with an outer circumferential surface of a drive shaft. The pickup sensor is supported by the metal ring.
