摘要： PROBLEM TO BE SOLVED: To provide a wheel bearing device that achieves a longer service lifetime of a bearing by solving the conflicting problem between weight-reduction/miniaturization and high rigidity.
SOLUTION: A vehicle-body mounting flange 7 is formed by forging. Bolt-insertion holes 10 are formed at several parts in the vehicle-body mounting flange 7. The side face 11 on the outer side at the peripheral edge of the bolt-insertion hole 10 in the part, where stress occurring at the root part becomes larger than that of the other parts, of the several parts is formed further protruding to the outer side than the side face 12 at the peripheral edge of each bolt-insertion hole 10 in the other parts. Each seat face 10a is formed at the peripheral edge of each bolt-insertion hole 10 by machining. Therefore, strength and rigidity is improved by changing the shape of only the part that becomes the most weakest part in the vehicle-body mounting flange 7. Consequently, a wheel bearing device is provided that achieves a longer service lifetime of a bearing by solving the conflicting problem between weight-reduction and high rigidity.
