Method for forming a bearing apparatus

A bearing is mounted on a hollow shaft of a hub wheel. A shaft end of the hollow shaft 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 is formed, betwe...

Zusammenfassung:	A bearing is mounted on a hollow shaft of a hub wheel. A shaft end of the hollow shaft 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 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 cushions deformation in the first area.
