PURPOSE:To automate the manufacture without using forging, cutting and cold press working means by adopting mainly the bulge method and using the swaging method as required in working a hollow change lever while using a steel tube as a raw material. CONSTITUTION:When the ratio of the diameter of a spherical shaft 3 to the diameter of a shaft 4 projected from both sides is at the outside of the range of limitation formed by the bulge working the swaging working is applied to a part scheduled for the shaft except for the working part of the spherical shaft 3 is formed to raw material steel tube 1 having a larger diameter than the finish diameter of the shaft 4 so as to apply a diameter adjusting working transited to a small diameter, the shaft 4 of a desired set diameter is worked precedingly and the bulge working is applied to the part scheduled for spherical shaft working not subject to the swaging working.
