PROBLEM TO BE SOLVED: To provide a constant velocity universal joint capable of realizing a high operating angle more than a conventional operating angle, without making a ball fall off. SOLUTION: This constant velocity universal joint has an outside joint member 1, an inside joint member 2, an outside cage 3, an intermediate cage 4 and an inside cage 5 incorporated between both mutual joint members, an outside ball 6 stored in a pocket 3d of the outside cage 3, an intermediate ball 7 stored in a pocket 4d of the intermediate cage 4, and an inside ball 8 stored in a pocket 5d of the inside cage 5. A ball track of mutually oppositely forming guide grooves 1b and 4b of the outside joint member 1 and the intermediate cage 4, and a ball track of mutually oppositely forming guide grooves 2b and 4e of the inside joint member 2 sand the intermediate cage 4, are formed in a wedge shape of mutually expanding in the inverse direction in the axial direction.
