Abstract
A wheel bearing device of the invention includes a flanged shaft member that includes a shaft portion to which a rolling bearing is assembled, a fitting shaft portion that is formed on one end side of the shaft portion and that is fitted to a center hole of a wheel, and a plurality of flange portions that extend radially outward on an outer peripheral surface located between the shaft portion and the fitting shaft portion and each of which has a through bolt hole in which a hub bolt for fastening the wheel is arranged. Each flange portion of the wheel bearing device is formed by side extrusion when a forged recess is formed at a center of an end surface of the fitting shaft portion by cold forging. An edge portion of a cross-sectional shape taken perpendicularly to a longitudinal direction of each flange portion is formed in an R-chamfered shape.
