摘要: A bearing (12) is mounted to a hollow shaft provided to a hub wheel (11). A shaft end of the hollow shaft (14) is deformed radially outward and caulked to an outer end face of an inner ring of the bearing. Between a first area in which a spline portion is formed and a second area in which a caulked portion (14a) is formed between a bending starting point for bending the shaft end radially outward and an end face of the shaft end on an inner peripheral face of the hollow shaft, a third area for suppressing deformation of the inner peripheral face of the hollow shaft caused by the caulking is formed. The third area (143) cushions deformation in the first area.
