To provide a bearing device for a wheel capable of maintaining the face-runout accuracy of a wheel attaching flange while reducing the weight, and improving its durability by enhancing the strength of the wheel attaching flange.

In the bearing device for the wheel in which the wheel attaching flange 6 and a pilot part 14 extending from the base part of the wheel attaching flange to the outer side are formed on the one end part of a hub ring 4, and a plurality of hub bolts 7 are press-fitted in the circumferential direction of the wheel attaching flange 6 at regular intervals, a conical recess 13 axially extending is formed on the outer side end part of the hub ring 4 and its depth is limited to near base part 6b, and a plurality of built-up parts 15 are formed on the inner circumference of the pilot part 14 by forging processing. Since the built-up parts 15 are disposed on the same phase position as the hub bolts 7, the strength of the wheel attaching flange 6 can be enhanced while reducing the weight, and stress generated in the corner part 16 of the pilot part 14 can be relaxed when a moment load is applied.
