Abrégé

[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.
