い。The lubricant supply groove in the above-mentioned annular washer is functionally formed only on the shaft-side end face of the cross shaft, but it is sufficient to form the lubricant washer into the bearing case of the annular washer. Although the front and back discrimination is performed so as not to be reversed when assembling, it is actually very difficult to measure the discrimination. Therefore, in order to omit the front / back discrimination work, a plurality of lubricant supply grooves are formed on both end faces of the annular washer. However, since a plurality of lubricant supply grooves are formed on both end faces of the ring-shaped washer, if the lubricant supply grooves on both surfaces are formed at the same position, the thickness of the supply groove portion becomes thin and the strength is reduced. There is. In order to prevent this reduction in strength, supply grooves are formed at regular intervals of 90 degrees on both end faces of the annular washer to shift the front and back phases by 45 degrees, and the thickness of the supply grooves is increased to secure the strength. However, it is difficult to form the number of lubricant supply grooves in consideration of the joint angle.

FIG. 1 is a partial sectional view of a universal joint according to the present invention, in which a shaft portion 5 of a cross shaft 4 is inserted into a bottomed bearing case 1 having a U-shaped cross section, and an inner peripheral surface of a cylindrical portion 3 of the bearing case 1. The peripheral surface 5a and the end surface 5b of the shaft portion 5 of the cross-shaft body 4 are supported by a needle roller 6 disposed on the inner surface of the shaft 2 and a ring washer 7 disposed on the inner surface of the bottomed portion 2. A lubricant passage 9 opening in the central space 8 of the
From the inner edge portion 11 to the outer edge portion 1 only on the end face 7a on the shaft portion 5 side.
2, a plurality of lubricant supply grooves 10 for supplying lubricant to the needle rollers 6 are formed. Note that a bearing member using a sliding member such as metal may be used instead of the needle roller 6.

いる。Further, as can be understood well in FIGS. 2A and 2B, the lubricant supply groove 10 of the annular washer 7 is formed.
A circumferential concave step 13 is formed on the inner edge 11 of the end face 7a on which is formed. That is, the annular washer 7 is formed with the lubricant supply groove 10 on the surface excluding the peripheral concave step portion 13.

であることを確認する。Next, the discrimination of the front and back sides when assembling the annular washer of the present invention will be described with reference to FIGS.
A cylindrical jig 14 having a diameter slightly larger than the diameter of the circumferential concave step 13 of the ring-shaped washer 7 is used, and a circumferential concave step 15 is formed on the outer diameter of the end face 14a to form a jig end 14b. The ring-shaped washer 7 can be fitted into the circumferential concave step 13. At this time, the diameter of the jig end portion 14b in which the circumferential concave step 15 is formed is larger than the diameter of the inner edge portion 11 of the ring-shaped washer 7. Therefore, FIG. 3 shows a state in which the annular washer 7 is normally assembled, and the jig end surface 14a is fitted into the peripheral concave step 11 of the annular washer 7 and the peripheral concave step 15 of the jig end surface 14a.
The bottom surface is in contact with the end face of the ring-shaped washer 7. A normal value of the position of the jig 14 at this time is checked with a measuring instrument 16 such as a dial gauge, and it is checked that the annular washer 7 is in a normal assembled state.

Is larger than the diameter of the inner edge 11 of the ring-shaped washer 7. Therefore, the end face 14a of the jig abuts against the end face of the ring-shaped washer 7, that is, the end part 14b of the jig is not fitted to the circumferential concave step portion 11 of the ring-shaped washer 7, so that the position of the jig 14 is measured in this state. If you check with appliance 16,
Jig end 14 having circumferential concave step 15 formed from a regular position
Since it is shifted by b, it can be confirmed that the ring-shaped washer 7 is in the reversely assembled state.

Since the circumferential concave step is formed, the front and back can be reliably and easily determined without reducing the strength of the annular washer. Also,
Since the lubricant supply groove is formed only on one side of the annular washer, the lubricant supply groove can be easily formed in consideration of the joint angle.
