PROBLEM TO BE SOLVED: To securely restrict fretting between a plastic deforming part of an outside joint member and an uneven part of a hub ring. SOLUTION: The outside joint member 41 of a constant velocity universal joint 4 is engaged in the inner circumference of the hub ring 10, and the plastic deforming part 34 of the outside joint member 41 on the inner diameter side is plastically deformed in a diametrically enlarging direction, so that the uneven part 31 in the inner circumference of the hub ring 10 bites it to couple the hub ring 10 to the outside joint member 41. An outer circumference of the plastic deforming part 34 is rough-surfaced, with its surface roughness set in a range of Ra1.6-12.5. COPYRIGHT: (C)2004,JPO
