摘要： A flange portion provided on a shaft member of a rolling bearing device for a wheel includes an outer flange portion; and an inner flange portion formed thicker than the outer flange portion as seen in a cross section. The inner flange portion is formed into a concavely-curved-inclining-surface-shape in which a flange surface shape on a side where a bolt seat surface portion for the hub bolt is disposed is such that the thickness of the inner flange portion gradually decreases as it extends radially outwards from a radially proximal end portion. The concavely-curved-inclining-surface-shape is formed as a surface shape in which the thickness of the inner flange portion decreases uniformly as it extends radially outwards with respect to a width direction the flange portion.

摘要： A shaft member of a rolling bearing device for a wheel includes a shaft portion, a flange base portion, and a fitting shaft portion. A plurality of flange portions which extend radially outwards in a radial direction is formed on the flange base portion. Projecting portions which are webbed-shaped and project radially outwards are formed circumferentially on an outer circumferential surface of the flange base portion between the adjacent flange portions.

摘要： [Problem] To provide a method of manufacturing a wheel rolling bearing device capable of manufacturing the wheel rolling bearing device using a simpler mold with higher efficiency, and capable of further enhancing rigidity of a caulked portion for securing an inner ring which is fitted to one end of a shaft portion.
[Means for Solution] An outer ring 45 and rolling elements 50 are fitted to a shaft member 1 of the wheel rolling bearing device from a shaft end portion 15, and further, an inner ring 42 and rolling elements 51 are fitted to the shaft member 1. Then, the shaft end portion 15 is caulked to form a caulked portion 17, and thus, the inner ring 42 is secured. On this occasion, the shaft end portion 15 to be caulked has a solid columnar shape. A caulking jig P is pressed against the shaft end portion 15, and oscillated while the caulking jig P is pressed in a direction toward one end of a shaft portion 10, thereby to spread by caulking a face 15M to be caulked in the shaft portion having the solid columnar shape.
摘要翻译：本发明的目的在于提供一种制造车轮用滚动轴承装置的方法，该车轮用滚动轴承装置能够使用更高效率且更简单的模具来制造车轮用滚动轴承装置，并且能够进一步提高用于确保嵌合于一方的内圈的铆接部的刚性轴部分的末端。 [解决手段]将外圈45和滚动体50从轴端部15嵌合在车轮用滚动轴承装置的轴部件1上，并且将内圈42和滚动体51嵌合在轴部件然后，轴端部15被敛缝以形成敛缝部分17，从而固定内环42。此时，被铆接的轴端部15为实心圆柱状。将铆接夹具P按压在轴端部15上，一边将铆接夹具P朝向轴部10的一端侧按压一边进行摆动，通过铆接面15M而进行铆接，实心柱状。
