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: A track groove 22 of an outer member has two kinds of a first track groove 41 and a second track groove 42. The first track groove 41 has the innermost side track groove 41a formed by making the curvature center axially dislocated to the innermost side from the joint center and a tapered opening side track groove 41b deepening toward the opening side from the innermost side. The second track groove 42 has the innermost side track groove 42a formed by making the curvature center axially dislocated to the innermost side from the joint center, an opening side track groove 42b of arranging the curvature center on the outer diameter side from the ball center, and a tapered groove 42c formed between the innermost side track groove 42a and the opening side track groove 42b and becoming shallow toward the opening side from the innermost side.
