Abstract:
A hub unit bearing includes a stationary side raceway ring, a rotating side raceway ring including a rotating side flange for fixing a vehicle wheel, and rolling elements rollably provided therebetween. The rotating side flange includes thin portions and thick portions arranged alternately in a circumferential direction. A hub bolt is serration-fitted to a bolt hole formed in each of the thick portions. An outer peripheral surface of the rotating side flange includes a large-diameter portion which has a larger radial thickness dimension with the bolt hole, a small-diameter portion which has a smaller radial thickness dimension with the bolt hole than the large-diameter portion, and a step portion which connects the large-diameter portion to the small-diameter portion. A serration-fitted portion does not radially overlap with the large-diameter portion.

Claim (Index 1):
A hub unit bearing comprising:\n a stationary side raceway ring which includes a stationary side raceway on a peripheral surface thereof; a rotating side raceway ring which includes a rotating side raceway on a peripheral surface thereof and a rotating side flange for fixing a vehicle wheel; and a plurality of rolling elements which are rollably provided between the stationary side raceway and the rotating side raceway, wherein the rotating side flange is formed in a plate shape as a whole and includes a plurality of thin portions and a plurality of thick portions arranged alternately in a circumferential direction, each thick portion having a larger axial thickness dimension than the thin portions, wherein a hub bolt is serration-fitted to a bolt hole formed in each of the thick portions, wherein an outer peripheral surface of the rotating side flange includes a large-diameter portion which has a larger radial thickness dimension with the bolt hole, a small-diameter portion which has a smaller radial thickness dimension with the bolt hole than the large-diameter portion, and a step portion which connects the large-diameter portion to the small-diameter portion, and wherein a serration-fitted portion does not radially overlap with the large-diameter portion.
