Claims

[Claims for Utility Model Registration] An outer joint member having a cylindrical shape with one end open and having a plurality of guide grooves extending in the axial direction on the inner periphery; In a constant velocity joint comprising an inner joint member having a plurality of tripod shafts protruding into a guide groove, and a roller member rotatably provided on each of the tripod shafts and rolling in the guide groove, the tripod shaft is 1 with a convex spherical outer peripheral surface
A cylindrical member is interposed between the tripod shaft and the roller member and has a concave spherical surface on its inner peripheral surface that slides on the convex spherical surface and is movable relative to the roller member in the roller axial direction. , and a retainer is provided at the bottom of the guide groove so as to be slidable in the longitudinal direction of the guide groove, and a retainer is provided between the retainer and the cylindrical member in a direction in which the axis of the cylindrical member coincides with the roller axis. A constant velocity joint characterized by being provided with a spring member that constantly urges the joint to face the same direction.
