SENSOR-INTEGRATED BEARING FOR WHEEL

A sensor-integrated wheel support bearing assembly includes an outer member (1) having a plurality of raceway surfaces (4), formed in an inner peripheral surface thereof, and also having a vehicle body fitting flange (1a) formed in an outer periphery thereof, and an inner member (2) having raceway surfaces (5) defined therein in alignment with the raceway surfaces (4) in the outer member (1). A plurality of rows of rolling elements (3) are arranged between the raceway surfaces (4) and (5) to enable a vehicle wheel (18) to be rotatably supported relative to a vehicle body structure. A load sensor (9) for detecting the load acting on the flange (1a) is disposed in a bolt insertion hole (21) provided in the vehicle body fitting flange (1a).
