Abstract:
A wheel bearing apparatus has a seal ( 8 ) with a metal core ( 15 ) and a sealing member ( 6 ). The metal core ( 15 ) is fit into an outer-side end inner circumference of the outer member ( 10 ). The sealing member ( 16 ) with a first side lip ( 16 a ) is adhered to the metal core. The first side lip ( 16 a ) is inclined radially outward to oppose a metal annulus ( 17 ) mounted on a base ( 18 ) of a wheel mounting flange ( 4 ), via an axial gap. The sealing member second side lip ( 16 b ) is formed radially inward from the first side lip ( 16 a ) and is in sliding contact with the base ( 18 ), via an axial interference. The sealing member third side lip ( 19 a ) is inclined radially outward from a base ( 19 ), covering the outer surface of the metal core ( 15 ), toward the wheel mounting flange ( 4 ). The tip end of the third side lip ( 19 a ) is formed with a vertically flat surface opposing the inner-side surface ( 4 b ) of the wheel mounting flange ( 4, 28 ), via an axial gap (S 1 ), to form a first labyrinth seal ( 20 ). The outer edge of the metal annulus ( 17 ) opposes a sealing member ( 16 ), via an axial gap, to form a second labyrinth seal ( 25 ).

Claim (Index 3):
The wheel bearing apparatus of  claim 1 , wherein a metal annulus is fit on the inner-side base of the wheel mounting flange, the seal opposes the metal annulus, the annulus is press-formed from a steel sheet and comprises a cylindrical fitting part, a curved part, an annular flat part and a bent part, the cylindrical fitting part is fit onto a shoulder part of the wheel hub, the curved part has a circular arc cross section corresponding to the base with a circular arc cross section, the annular flat part extends radially outward from the curved part and closely contacts the inner-side surface of the wheel mounting flange, via an elastic member, the bent part extends radially outward from the radially outermost part of the annular flat part and axially apart from the wheel mounting flange, and the inner-side base of the wheel mounting flange has a circular arc cross section of a radius of curvature (r) and the curved part of the metal annulus has a circular arc cross section of the radius of curvature (R) where respective radii of curvatures (R), (r) are set as R\u2265r.
