Constant velocity universal joint

摘要

A constant velocity universal joint (10) comprises a plurality of trunnions (26a to 26c) which are formed to be spherical, sliding surfaces (24) which extend in a flat configuration along an axial direction of an outer cup (12), and pairs of slipper members (22a, 22b) having one side surfaces which are formed with recesses (28) for making contact with spherical surfaces of the trunnions (26a to 26c) and the other side surfaces which are formed with flat surfaces (30) to make contact with the sliding surfaces (34), wherein the pair of slipper members (22a, 22b) are provided slidably with respect to the sliding surface (24) and the spherical surface of the trunnion (26a to 26c).
