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 1):
A wheel bearing apparatus comprising:\n an outer member, an outer member inner circumference includes double row outer raceway surfaces; an inner member, an inner member outer circumferences includes double row inner raceway surfaces opposing the double row outer raceway surfaces; double row rolling elements are rollably accommodated in a space between the inner raceway surfaces of the inner member and the outer raceway surfaces of the outer member; a wheel mounting flange for mounting a wheel, via a brake disc, is formed on a rotary-side of one of the outer member or the inner member; hub bolts, to fasten the wheel, are secured equidistantly along the wheel mounting flange; an annular groove is formed on the outer-side surface of the wheel mounting flange, the annular groove includes a region where the hub bolts are mounted, weight reduction apertures are formed between hub bolts on the wheel mounting flange, a diameter of a circumscribed circle circumscribing the weight reduction apertures is set larger than an outer diameter of the annular groove or the weight reduction apertures are opened to an outer circumferential surface of the wheel mounting flange.
