A hub bearing device is provided to reduce manufacturing costs, and not to generate run-out due to a flange by not having to install the flange in an outer ring so as to allow the outer ring to be connected to a knuckle. A hub bearing device comprises a bearing(110), a knuckle(120) and a hub(130). The bearing includes an outer ring(111) forming a track, one inner ring(113) or more forming the track, a plurality of rolling elements(115) located between the outer ring and the inner ring so as to be rolled, and a cage(119) forming a concave groove for being inserted by the rolling element. The knuckle includes an inner diameter part(121) inserted by the outer ring, and connected to a suspension of a vehicle. The hub includes a cylinder part(131) forming a mount part where the inner ring of the bearing is mounted, and a flange(133) formed to be extended in radius direction from the cylinder part. |
