<p>It is intended that the induced thrust and slide resistance of a constant velocity joint should be further reduce. To this end, there is provided a constant velocity joint comprising an outer joint member 10 having three track grooves 12 each having circumferentially opposed roller guide surfaces 14, a tripod member 20 having three radially projecting leg shafts 22, a roller 34 inserted in each track groove 12, and a ring 32 fitted on each leg shaft 22 to rotatably support the roller 34, the roller 34 being movable along the roller guide surfaces 14 axially of the outer joint member 10, wherein the roller 34 consists of a set of annular roller portions 34a and 34b, with a plurality of balls 36 interposed between outer raceway surfaces 35a and 35b formed on the inner periphery of the annular roller portions 34a and 34b and a single inner raceway surface 33 formed on the outer periphery of the ring 32. <IMAGE> <IMAGE></p> |
