A constant velocity joint includes an outer race having a plurality of ball grooves formed in an inner spherical surface thereof, which ball grooves extend in a direction of a rotation axis of the outer race, an inner race having a plurality of ball grooves formed in an outer spherical surface thereof, which ball grooves extend in a direction of a rotation axis of the inner race and are paired with the ball grooves of the outer race, and a plurality of balls disposed between the ball grooves of the outer race and the ball grooves of the inner race. In the constant velocity joint, the ball grooves of at least one of the outer race and the inner race are partially formed wit relief profiles to provide a plurality of relief groove portions such that a load applied to each of the balls located in the relief groove portions during torque transmission between the inner race and the outer race is smaller than a load applied to each of the balls located in the other portions of the ball grooves. |
