PROBLEM TO BE SOLVED: To provide a constant velocity universal joint which improves assemblability to an outside joint member of boot, and fully keeps sealing performance between the boot and the outside joint member. SOLUTION: The constant velocity universal joint includes an outside joint member 10 in which an opening section 11 is provided in one end, a plurality of track grooves 12 axially extended are formed on an inner circumferential surface, and concave portions 18 axially extended are formed at portions corresponding to between the track grooves 12 of peripheral surface, and a tripod member 20 which transmits a torque while permitting an angular displacement through a roller 30 arranged with the track groove 12 of the outside joint member 10, wherein a convex section 48 corresponding to the concave section 18 of end section inner circumferential surface of cylindrical boot 40 closing the opening section 11 of the outside joint member 10 is formed, and the end section inner circumferential surface of the boot 40 is interfit into an opening section peripheral surface of the outside joint member 10. Furthermore, a boot displacement preventing mechanism, which has a projection 13 in the opening section peripheral surface of the outside joint member 10 and a convex groove 43 interfit with the projection 13 in the end inner circumferential surface of the boot 40, is provided.
