Abstract
A constant-velocity universal joint including a generally cup-shaped outer joint member and an inner joint member that cooperate with each other to define first and second groove portions. A pinch angle by which a ball is pinched in the first groove portion is open toward an opening end of the outer joint member. A pinch angle by which the ball is pinched in the second groove is open toward a bottom wall of the outer joint member. An absolute value of the pinch angle in the first groove portion is larger than an absolute value of the pinch angle in the second groove portion in a reference state in which centerlines of the outer joint member and the inner joint member lie in a straight line.
