ている。2. Description of the Related Art The above-mentioned bearing device for an axle has various structures, but the outer ring of a hub wheel or a double row rolling bearing is manufactured by lathe technology such as turning.
【０００３】[0003]
【発明が解決しようとする課題】上記従来例では、ハブ
ホイールや複列転がり軸受の外輪を旋削加工しているの
で、製造コストが高いために、近年におけるコスト低減
の要求に答えられない。In the above-mentioned conventional example, since the hub wheel and the outer ring of the double row rolling bearing are turned, the manufacturing cost is high, and thus the demand for cost reduction in recent years cannot be met.
【０００４】これに対し、製造コストを低減する目的か
ら、例えば特開平７−３１７７７５号公報に示すよう
に、ハブホイールや複列転がり軸受の外輪について、板
材を用いて深絞り加工により製作することが考えられて
いる。On the other hand, for the purpose of reducing the manufacturing cost, for example, as shown in Japanese Patent Laid-Open No. 7-317775, the outer ring of a hub wheel or a double row rolling bearing is manufactured by deep drawing using a plate material. Is being considered.

う。As described above, when a hub wheel or an outer ring of a double row rolling bearing is manufactured by deep drawing, a thick plate material is used to secure sufficient strength as a base material.
Since it is difficult to process and the shape accuracy of the bent portion is likely to decrease, precision technology is required to improve the accuracy, resulting in poor production efficiency despite the press processing.

く、その分、コスト増を余儀なくされる。Further, in the conventional example, since the centering portion for the wheel or the vehicle body side member is not provided for the outer ring of the hub wheel or the rolling bearing, the centering of a separate body is performed for the outer ring of the hub wheel or the rolling bearing. There is no choice but to retrofit the members, which inevitably increases costs.

Among the separation pieces separated in the circumferential direction by 4, 27, every other separation piece in the circumferential direction is bent outward in the radial direction from the root side to form the cut-and-raised pieces 11, 24. In this bending step, the cut-and-raised pieces 11 and 24 are placed in a posture along the radial direction by using a receiving die and a pressing die. A pair of concave and convex portions are provided separately, and by the convex and concave portions, the predetermined regions of the cut-and-raised pieces 11 and 24 are projected in the axial direction, thereby increasing the total axial width dimension and ensuring weight reduction and strength. I try to achieve both. The non-bent separation pieces become the tongue pieces 12 and 25,
