摘要： A hollow steering shaft having a good quality can be manufactured at a low cost by passing a blank tube having a circular cross section through a preliminary shaping die and then through a finishing shaping die. The blank tube which has passed through the preliminary shaping die is formed with two kinds of convex curve surface portions having different radii of curvature and arranged continuously, circumferentially and alternately. When the blank tube passes through the finishing shaping die, the larger convex curve surface portions are deformed into flat portions. As a result, a steering shaft having an elliptical cross section is manufactured.

摘要： A yoke for universal joint is composed of a cylindrical coupling tube formed by pressing a metal plate and having a slit in a radial direction and serrate grooves on the internal periphery; a pair of flanges integrally formed at an end of the coupling tube and positioned on both sides of the slit; and a coupling arm formed by pressing a metal plate. One of the flanges has a screw hole, while the other flange has a hole, coaxial with the screw hole, for passing a bolt to be screwed into the screw hole. The coupling arm has a penetrating hole in the base portion, and mutually coaxial circular holes at its opposite ends. The yoke is assembled by fitting the other end of the coupling tube into the penetrating hole in the base portion, and connecting the other end of the coupling tube with the base portion of the coupling arm.
