A cross groove variety of constant velocity universal joint includes an inner race having a plurality of grooves formed in an outer surface thereof and an outer race having a plurality of grooves formed in an inner surface thereof. For each pair of associated inner and outer race grooves, the inner race groove is inclined in one direction relative to the rotational axis of the joint, while the outer race groove is inclined in the opposite direction. A ball is disposed in each of the associated inner and outer race grooves for providing a driving connection between the inner and outer races. A cage is provided with openings for retaining the balls in the grooves. The cage openings are formed having angled side walls which open up toward the center of the joint. The angled side walls are effective to position the point of contact between the balls and the angled side walls away from a lower edge surface of the cage. Consequently, an inner bore radius of the cage can be increased to allow greater angular motion and axial movement of the joint. Also, the balls are pinched against the angled side walls during operation of the joint to prevent the cage from chattering.
