    Abstract: A vehicle wheel bearing apparatus has a seal with a metal core and a sealing member. The metal core includes a cylindrical fitting portion press-fit into an end of the inner circumference of an outer member. A radially inner portion extends radially inward from the fitting portion. The sealing member is integrally adhered to the metal core. The sealing member has a side lip that is radially outwardly inclined. Either one of the metal core or the sealing member is formed with a weir portion that extends radially outward from the fitting portion of the metal core. The weir portion opposes the inner-side surface of the wheel mounting flange, via a small axial gap, to form a labyrinth seal. The weir portion also opposes the outer-side end face of the outer member, via a predetermined axial gap, to form an annular discharging groove.
