Method for forming a wheel bearing unit
摘要:
Attachment holes are formed in a plurality of locations in the circumferential direction of the attachment flange of a wheel bearing unit. The amount “h” of projection from an attachment surface in the axial direction of the opening edge peripheral portion of the respective attachment holes is limited under the condition that studs are press-fitted and fixed into the respective attachment holes.
