PROBLEM TO BE SOLVED: To solve a problem that although a cylindrical member 103 shown in Figure (c) is conventionally used, since this cylindrical member 103 is integrally provided with centering projections 75a, 75b and clutch inners 76a, 76b, a manufacturing cost is increased. SOLUTION: The figure (a) is a deal drawing and an intermediate member 26 in which a male spline 29 is formed on a cylinder 27 and simple pipe-like right and left extension members 30L, 30R are prepared. The figure (b) is an assembling drawing and ends of right and left extension members 30L, 30R are friction-joined to both ends of the cylinder 27 to integrally form them. The obtained integral shaft can be manufactured at a low cost.
