Abstract
A bearing device in which a rolling bearing is fitted on one axial end of a shaft and in which the one axial end of the shaft is caulked to fix the rolling bearing while preventing the same from coming out. The shape of the outer end face of the caulked portion is devised to maximize the resistance to the coming-out by the caulked portion.
