Abstract:
A wheel bearing apparatus includes an outer ring, an inner shaft member, rolling elements, a cage, and a sealing device. The sealing device includes an annular slinger and a sealing member. The slinger has a first inclined surface provided on a radially outer side and on a side facing the sealing member such that a diameter of the first inclined surface increases toward a first side in an axial direction. The sealing member has a second inclined surface provided on the radially outer side and on a side facing the slinger such that a diameter of the second inclined surface increases toward a second side in the axial direction. The second inclined surface intersects with a virtual extension surface extending radially outwardly along the first inclined surface, and the second inclined surface is continuous with an inner peripheral surface of the radially outer portion.

Claim (Index 1):
A wheel bearing apparatus comprising:\n an outer ring attached to a vehicle-body-side member; an inner shaft member including a flange portion to which a wheel is attached, the flange portion being provided at a position on a first side in an axial direction; a plurality of rolling elements provided in an annular space between the outer ring and the inner shaft member; a cage configured to hold the plurality of rolling elements; and a sealing device provided on a second side in the axial direction and configured to prevent foreign matter from entering the annular space from between the outer ring and the inner shaft member, wherein: the sealing device includes\n a slinger having an annular shape and attached to the inner shaft member at a position on the second side in the axial direction, and \n a sealing member including a radially outer portion having a cylindrical shape and attached to the outer ring at a position on the second side in the axial direction so as to face an outer peripheral surface of the slinger via a gap, a radially inner portion extending radially inwardly from the radially outer portion, and a lip extending from the radially inner portion so as to be in contact with the slinger; \n the slinger has a first inclined surface provided on a radially outer side and on a side facing the sealing member such that a diameter of the first inclined surface increases toward the first side in the axial direction; \n the sealing member has a second inclined surface provided on the radially outer side and on a side facing the slinger such that a diameter of the second inclined surface increases toward the second side in the axial direction; and \n the second inclined surface intersects with a virtual extension surface extending radially outwardly along the first inclined surface, and the second inclined surface is continuous with an inner peripheral surface of the radially outer portion.
