PROBLEM TO BE SOLVED: To properly position an inner ring with respect to a ball nut in a simple style, by improving the ball nut for a ball screw.SOLUTION: A support ring is fixed to the ball nut 6 in a roller vanishing working process, in order to arrange the support ring shape-connectingly to the ball nut 6 in an axial-directional support direction by material deformation, and a deformed material of the support ring is pressed into an inside of a cut-out of the ball nut 6, in particular, formed of a groove, by the roller vanishing working process. |
