The universal joint cruciform shaft 1 is provided with an oil supply hole 2, and the shaft 3 of the cruciform shaft 1 is provided with an oil reservoir 4 communicating with the oil supply hole 2. The oil controller 5 is arranged. A flange 6 is provided in the opening of the oil controller to form a grease keeper 7 including the oil controller 5 and the flange 6, and the grease keeper is arranged so that the flange of the grease keeper is outward. . The outer diameter of the flange 6 is larger than the outer diameter of the end surface of the shaft 3 so that the outer peripheral portion supports one end of the needle roller 8.

定し得る利点もある。(Effect) Since the present invention is configured as described above, the cost can be reduced and the assembling can be facilitated by adopting the grease keeper in which the oil controller and the thrust washer are integrally formed. Conventionally, there is an example in which a ring-shaped collar is used to support one end of the needle roller, but by adopting a grease keeper with a flange on the oil controller, the number of parts is reduced and a universal joint is manufactured at low cost. There is an advantage that can be. Further, since the load of the needle roller in the axial direction can be supported by the flange of the grease keeper, the life of the needle roller and the bearing cap can be improved. Further, this grease keeper can prevent seizure and wear of the shaft end of the cross shaft. When a porous oil controller is used, it serves as a filter against foreign substances mixed in the grease, and at the same time, it holds the liquefied grease and helps lubrication. Further, the oil groove and oil hole formed in the grease keeper are very effective for lubrication. Further, since a material such as plastic can be adopted as the material of the flange of the grease keeper, it can slide more smoothly than the conventional machined surface that rolls. By pouring the grease keeper into the oil sump 4 and then machining the end surface of the grease keeper's flange, the cross-shaped shaft and bearing cap can be easily attached without the need to precisely grind the shaft end of the cross-shaped shaft. There is also the advantage that the position can be determined.
