The utility model relates to a hub unit bearing for supporting a wheel of an automobile in a free rotating manner relative to a suspension device. In the hub unit bearing, a hub bolt is fitted in a comb in a bolt hole provided in a thick wall portion of a rotation-side flange, and the outer peripheral surface of the rotation-side flange has a large-diameter portion having a large outer diameter dimension, a small-diameter portion having a smaller outer diameter dimension than the large-diameter portion, and a step portion connecting the large-diameter portion and the small-diameter portion. Since the portion where the comb teeth are fitted does not overlap the large-diameter portion in the radial direction, a hub bolt for fixing a wheel and a brake rotating member is stably fitted and fixed with respect to a bolt hole of the rotating-side flange.
