Claims

[Claims for Utility Model Registration] (1) The roller guide surfaces on both sides of the track groove provided on the inner surface of the outer ring are planes parallel to the plane containing the axis of the outer ring and the center of the track groove, and the roller is cylindrical. An inner and outer guide ring is interposed between the cylindrical roller and the leg shaft, the outer circumference of the inner guide ring fitted on the outside of the leg shaft is a spherical surface, and the inner surface of the outer guide ring is a concave spherical surface that fits with the spherical surface. and a spacer is interposed at the base of the leg shaft, so that the outer guide ring is rotatable about an axis that is at least perpendicular to the axis of the leg shaft and parallel to the axis of the tripod member. constant velocity universal joint. (2) The spacer has an annular protrusion of a predetermined height formed on one side surface for restricting rotation of the outer guide ring to a predetermined amount. Constant velocity universal joint according to item 1. (3) The spacer has a protrusion passing through its center on one side, and the outer guide ring has an axis that is perpendicular to the axis of the leg shaft and parallel to the axis of the tripod member. 2. A constant velocity universal joint according to claim 1, which is characterized in that the constant velocity universal joint is rotatable only in the circumferential direction. (4) The constant velocity universal joint according to claim 1, wherein the spacer is formed of a disc spring that can be elastically deformed by a predetermined amount in the axial direction.
