Claims

[Claims for Utility Model Registration] A bearing 11 is provided at the outer end of each shaft 10a of the cross shaft body 10.
The yokes 12 and 13 are rotatably connected through the cross shaft body 10, and a radial grease hole 14 extending from the center to the outer end surface of each shaft 10a and a grease inlet 17 communicating with the grease hole 14 are provided in the cross shaft body 10. In the universal joint, the grease valve is inserted into the outer end of the grease hole 14 of each shaft 10a in order to control the amount of grease supplied to the bearing 11. The case 31 inserted into the end has a grease reservoir 34 formed on the inner end side of the case 31, one side communicating with the outer end side of the grease reservoir 34 and the other reaching the outer end surface of the case 31, and a grease reservoir 34 formed on the inner end side of the case 31. A first grease hole 35 located on the side of the grease reservoir 34, a second grease hole 36 located on the outer end surface side of the case 31 and having an inner diameter smaller than the first grease hole 35, and a second grease hole 36 that moves inward and outward directions into the grease reservoir 34. a ball 38 that is freely held and has an outer diameter larger than the inner diameter of the first grease hole 35; a spring 39 that is disposed within the first grease hole 35 and biases the ball 38 toward the inner end; and a case. 31, a grease inlet 41 provided on the peripheral wall of the grease reservoir 34 in a portion closer to the outer end than the center of the ball 38, and a grease hole 14 in the case 31 and the cross shaft 10.
A grease valve in a universal joint, in which a grease passage 44 is formed between the peripheral wall of the universal joint and communicates the grease inlet 41 with the inner part of the grease hole 14.
