Abstract
A wheel bearing device (1) provided with an outer sealing member (7) in which: a core metal (8) having formed therein multiple seal lips is fitted to the outer opening of an outer ring (2); a metal ring (9) is fitted to the outer peripheral section of a hub ring (3) so as to oppose the core metal. The multiple seal lips are brought into contact with the metal ring, so that a portion between the outer ring and the hub ring is sealed. An annular outer member side weir part (11f) that protrudes to the outer side, in a radial direction, as compared to the outer edge of the metal ring so as to surround the metal ring is provided to the core metal, and an outer member side expanded-diameter part (8g) that holds grease is formed in the inner peripheral surface of the outer member side weir part.
