ABSTRACT:
A spline forming die is made up of: upper and lower ring-shaped holders; and rollers vertically rotatably retained between the upper and lower holders and projected from a circumferential end of a holder. Using this spline forming die, splines having a stable precision in a spline-forming direction are formed by a press load due to the rotation of the rollers without the metal stock being subject to shearing friction. Further, a large module of splines can also be formed by setting the diameter of each of the rollers to a large size.
