Abstract:
The wheel bearing apparatus has hub bolts ( 6 a ) to fasten a wheel secured equidistantly around the wheel mounting flange ( 6 ). An annular groove ( 7 a ) is formed on the outer-side surface ( 7 ) of the wheel mounting flange ( 6 ). The annular groove ( 7 a ) includes a region where the hub bolts ( 6 a ) are mounted. The outer-side surface ( 7 ) of the wheel mounting flange ( 6 ) is formed as a cut surface cut after press-fitting of the hub bolts ( 6 a ). Weight reduction apertures (circular apertures) ( 13 ) are formed between the hub bolts  6 a  of the wheel mounting flange ( 6 ). A diameter of a circumscribed circle øA circumscribing the circular apertures ( 13 ) is set larger than an outer diameter øB of the annular groove ( 7 a ). Accordingly, muddy water is easily discharged from the circular apertures ( 13 ).

Claim (Index 6):
The wheel bearing apparatus of  claim 1 , wherein cut-off parts are formed on the outer circumference of the wheel mounting flange between bolt apertures where the hub bolts are press-fit, the cut-off parts keeping clear of near the bolt apertures, and each of the cut-off parts is formed with a circular arc shape so that deepest portions of the cut-off parts are positioned in proximity to a pitch circle diameter of the bolt apertures.
