曲面を描く。According to the yoke working method of the present invention, after the race hole is formed by the boring machine, the machining spindle is simply transferred without transfer to another machining machine and without changing the machining spindle. Replacing the cutting tool with respect to, the snap ring seating surface can be cut on the inner surface of the yoke starting from the position where the yoke is displaced from the center axis of the race hole into which the bearing case fits in the direction of the base of the yoke. The step shoulder generated by forming the surface is not concentric with the race hole, but draws an eccentric curved surface close to the center axis of the race hole.
