Abstract
A slide-type constant velocity universal joint has an inner shaft member having trunnions rotatably and axially slidably carrying rollers respectively received in axial guide grooves formed in an outer shaft member. Each guide groove accommodates a pair of inner groove members each axially slidably disposed between one of the side faces of the guide groove and an associated roller and providing a cylindrical inner groove in line contact with a spherical outer surface of the roller. A roller bearing or a low-friction layer is disposed between each inner groove member and an associated side face of an associated guide groove. In another embodiment, a single inner groove member is disposed in each guide groove and has a pair of side wall portions each disposed between a roller and an associated side face of the guide groove.
