<P>PROBLEM TO BE SOLVED: To connect firmly an inner ring to a shaft by preventing the generation of backlash to the utmost. <P>SOLUTION: In a fitting structure between the inner ring and the shaft installed in this constant-velocity universal joint, and equipped with the inner ring 20 for transferring torque, while allowing angle displacement between itself and an outer ring, and the shaft 50 pressed into an axial hole inner diameter 26 of the inner ring 20, the axial hole inner diameter 26 of the inner ring 20 is in an uncured state, and a spline 54 as an irregular part along the circumferential direction is formed at an axial end outer diameter 52 of the shaft 50, and a cured layer n is formed at the axial end outer diameter 52, and the axial hole inner diameter 26 of the inner ring 20 is formed in a tapered shape reduced in diameter toward the press-fitting direction, and the axial end outer diameter 52 of the shaft 50 is pressed into the axial hole inner diameter 26 of the inner ring 20, to thereby plastically couple the shaft 50 with the inner ring 20. <P>COPYRIGHT: (C)2008,JPO&INPIT |
