Claims

[Claims for Utility Model Registration] A tripod case integrated with the input shaft, a trunnion shaft provided at the end of the output shaft located inside the tripod case perpendicular to the shaft, and a trunnion shaft that rotates on the trunnion shaft. A tripod roller, which is freely disposed, rolls along the roller groove of the tripod case when the input shaft and output shaft intersect and rotate, and has a partially spherical peripheral surface. In the joint, the side surface of the roller groove in which the circumferential surface of the joint roller slides is constituted by a pair of mutually flat surfaces extending parallel to the axial direction of the trunnion shaft and parallel to the input shaft; A tripod joint characterized by being provided with a washer that prevents the joint roller from moving in the axial direction of the shaft.
