PROBLEM TO BE SOLVED: To provide a constant velocity universal joint excellent in productivity capable of preventing slipping out of an interior component such as an inner ring without using a stopper ring and to provide a manufacturing method of its outer ring. SOLUTION: The constant velocity universal joint is equipped with the cup-shaped outer ring 2 having a track groove 1 formed on the inner diameter surface, the inner ring 4 having a track groove 3 formed on the outer diameter surface, a ball 5 interposed between the track groove 1 of the outer ring 2 and the track groove 3 of the inner ring 4, and a cage 6 arranged between the inner diameter surface of the outer ring 2 and the outer diameter surface of the inner ring 4 for holding the ball 5. The cup-shaped outer ring 2 is a press-molded article from a plate material, and has the inner diameter surface and the track groove 1 formed at the time of press-molding. A through-hole 12 through which a shaft 8 connected to the inner ring 4 penetrates is provided to a bottom wall 11 of the outer ring 2. COPYRIGHT: (C)2007,JPO&INPIT
