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. In a tripod joint consisting of a joint roller that is freely provided and rolls along the roller groove of the tripod case when the input shaft and output shaft intersect and rotate, the joint roller is・Lace and inner lace and needle between both laces・
A pair of mutually flat side surfaces extending parallel to the axial direction of the trunnion shaft and parallel to the input shaft; A tripod joint, characterized in that the outer peripheral surface of the trunnion shaft that rotatably supports the inner race is formed into a partially spherical shape, and the outer peripheral surface of the trunnion shaft rotatably supports the inner race. .
