Abstract
A wheel bearing device comprises a rotor having a double row of raceway surfaces and having a wheel fixed thereto, an outer ring having a double row of raceway surfaces and a flange to be fixed to a knuckle disposed on the car body side, and a double row of rolling bodies interposed between the respective raceway surfaces of the rotor and outer ring. A pulser ring is disposed between the double row of raceway surfaces of the rotor, and a sensor opposed to the pulser ring is held by a holding member held between the flange of the outer ring and the knuckle, whereby the sensor can be disposed in the bearing inner space.
