Abstract
This slidable constant velocity universal joint comprises an outer joint member,, and a tripod member,having a plurality of axially extending leg shafts,and outer rings,which are rotatably fitted on the leg shafts,and whose outer peripheries,are spherical. The tripod member,is received inside the outer joint member,, and the outer rings,of the tripod member,are fitted in track grooves,in the outer joint member,so that they are slidable axially of the outer joint member. A sliding contact region S where relative sliding between the outer ring,and the leg shaft,in the leg shaft direction occurs is defined between the outer ring,and the leg shaft,, and the outer ring,is allowed to swing around the axis of the leg shaft,. The center of curvature O of the outer periphery of the outer ring,coincides with the sliding contact region S, thereby preventing the outer ring,from exhibiting unstable behavior before and after specific phases (0°, 180°).
