Abstract
In a rolling bearing device for a road-wheel including an inner shaftthat is provided with, on its outer-side end, a flangeon which a road-wheel member mounted, and an outer ringdisposed around the inner shaft, the inner shaft has, on its outer side, a hair-line pattern portionthat is formed by turning and that permits the manufacturing attribute of the bearing device to be identified based on the difference in the form of hair lines so formed. This permits the manufacturing attribute of the bearing device to be identified after the bearing device is assembled in a vehicle body. Furthermore, the representation of the manufacturing attribute can be readily implemented during a manufacturing step.
