PROBLEM TO BE SOLVED: To provide a fixed constant velocity universal joint capable of improving durability at a high angle, while keeping a high operating angle. SOLUTION: This fixed constant velocity universal joint has an outer member of axially forming a plurality of track grooves 22 at equal intervals in the circumferential direction on an inner spherical surface 21, an inner member of axially forming the plurality of track grooves 22 at equal intervals in the circumferential direction on an outer spherical surface 24, a plurality of balls 27 transmitting torque by being interposed between the track grooves 22 of the outer member and the track grooves 25 of the inner member, and a cage 28 holding the balls 27 by being interposed between the inner spherical surface of the outer member and the outer spherical surface of the inner member. The track grooves 22 of the outer member have the innermost side track groove 22a formed by making the curvature center axially dislocated to the innermost side from the spherical surface center of the outer member from the joint center, and a tapered opening side track groove 22b deepening toward the opening side from the innermost side.
