PROBLEM TO BE SOLVED: To provide a constant velocity joint having improved durability by reducing bearing pressure on guide grooves when contacting a ball. SOLUTION: The cross sectional face of the first guide grooves 26a-26f formed in the inner wall face of an outer cup 16 is formed in an arcuate shape to come into contact with the ball 28 at one point B. The cross sectional face of the guide grooves 32a-32f provided in the outer peripheral face of an inner ring 34 is formed in an elliptic shape to bring into two point (F, E)-contact with the ball 28.
