摘要： A wheel bearing device of the invention includes a flanged shaft member that includes a shaft portion to which a rolling bearing is assembled, a fitting shaft portion that is formed on one end side of the shaft portion and that is fitted to a center hole of a wheel, and a plurality of flange portions that extend radially outward on an outer peripheral surface located between the shaft portion and the fitting shaft portion and each of which has a through bolt hole in which a hub bolt for fastening the wheel is arranged. Each flange portion of the wheel bearing device is formed by side extrusion when a forged recess is formed at a center of an end surface of the fitting shaft portion by cold forging. An edge portion of a cross-sectional shape taken perpendicularly to a longitudinal direction of each flange portion is formed in an R-chamfered shape.

摘要： A hub unit for vehicle according to the invention includes a flange formed with plural bolt-hole groups each of which includes plural bolt holes each having a female thread of the same nominal diameter formed in its inside surface and each of which has a hole-pattern of the bolt holes circumferentially arranged on the same pitch circle diameter with equal spacing. The plural bolt-hole groups are mutually different in at least either one of the nominal female-thread diameter and the pitch circle diameter R, so that plural types of components having different hole-patterns may be directly mounted to the flange without using an adaptor as an independent member. This leads to cost reduction.
摘要翻译：根据本发明的用于车辆的轮毂单元包括形成有多个螺栓孔组的凸缘，每个螺栓孔组包括多个螺栓孔，每个螺栓孔具有形成在其内表面中的相同公称直径的阴螺纹，并且每个具有孔图案的螺栓孔以相等的间距圆周地布置在相同的节圆直径上。多个螺栓孔群在公称内螺纹直径和节圆直径R中的至少一个中是相互不同的，因此具有不同孔图案的多种类型的部件可以直接安装到法兰上而不使用适配器作为独立成员。这导致成本降低。

摘要： A W plug (24) is formed and a W oxidation preventing barrier metal film (25) is formed thereon. After that, an SiON film (27) thinner than the W oxidation preventing barrier metal film (25) is formed and Ar sputter etching is performed on the SiON film (27). As a result, the shape of the surface of the SiON film (27) becomes gentler and deep trenches disappear. Next, an SiON film (28) is formed on the whole surface. A voidless W oxidation preventing insulating film (29) is composed of the SiON (28) film and the SiON film (27).
