Abstract: A method for manufacturing a vehicle bearing apparatus includes a method for manufacturing a hub ring. The hub ring includes a seal facing surface, a flange portion, and a shaft body portion. The flange portion includes a thin portion, a thick portion, bolt holes, a thin portion outer surface, a thick portion outer surface, and bolts. The flange portion protrudes outward from the shaft body portion. The thick portion is formed on an outer side with respect to the bolt holes in the flange portion, and the thin portion is formed on an inner side with respect to the thick portion in the flange portion. In the method for manufacturing the hub ring, machining is performed on the thick portion outer surface by using the seal facing surface subjected to grinding, as a reference surface, after the bolts are fitted into the flange portion.
