A slidable type constant velocity universal joint comprising an outer member formed with at least three axially extending guide grooves disposed in parallel to one another, and an inner member disposed inside the outer member and provided with at least three radially extending pods projecting therefrom, the respective pods being in engagement, via respective rollers mounted thereon so as to be rotatable and slidable, within the respective guide grooves. The respective rollers are so mounted on the respective pods so as to be, additionally, tiltable in all directions so that the rollers will always be in longitudinally aligned relation in the guide grooves. Each pod is formed with an outer surface with curved generatrices and the surface can be, for example, a spherical surface of comparatively large curvature, and each roller can be formed with an inner surface supported on the pod surface via suitable bearings or guide rings for undergoing universal movement thereon. |
