PROBLEM TO BE SOLVED: To make separable an inner member and an outer joint member along an axial direction by simple structure, and to allow highly reliable driving at low cost. SOLUTION: The inner member 1 comprises a hub ring 2 and an inner ring 3, a small-diametric stepped part 8 of the inner ring 3 is internally fitted to the hub ring 2, an engaging part 8b of the stepped part 8 is engaged with an uneven part 7 formed in the hub ring 2, a diameter of the engaging part 8b is enlarged to be bit in the uneven part 7 and to be coupled plastically, and a set screw 25 engaged with a male spline 9a formed in a connection part 9 of the inner ring 3 and a recessed part 9b formed in a female spline 3a formed in a shoulder part of the outer joint member 21 is attached to the shoulder part 23 detachably diametric-directionally so as to make the inner member and the outer joint member separable along the axial direction. |
