Claims

[Scope of Claim for Utility Model Registration] (1) An outer member having an axial guide groove formed on its inner diameter surface, an inner member having an axial guide groove formed on its outer diameter surface, and the guide groove and inner part of the outer member. It consists of a ball that is interposed between the guide groove of the outer member and transmits torque, and a retainer that is located between the inner diameter surface of the outer member and the outer diameter surface of the inner member and holds the ball. A constant velocity universal joint in which at least one of the outer diameter surface of the central member and the inner diameter surface of the retainer that is in contact with the outer diameter surface is sloping at both ends. (2) The constant velocity universal joint according to claim 1, wherein the inner diameter surface of the retainer and the outer diameter surface of the inner member are in spherical contact. (3) The inner diameter surface of the cage and the outer diameter surface of the inner member are
Claim 1: The angular contact is made at a position equidistant from the width center of the inner diameter surface of the cage in the axial direction.
constant velocity universal joint. (4) The constant velocity universal joint according to claim 3, wherein the inner diameter surface of the retainer comprises a pair of surfaces having a concave arc shape in cross section and symmetrical with respect to the width center. (5) The constant velocity universal joint according to claim 3, wherein the inner diameter surface of the retainer comprises a pair of surfaces having a straight cross section and symmetrical with respect to the width center. (6) The constant velocity universal joint according to claim 3, wherein the inner diameter surface of the retainer comprises a pair of surfaces having a convex arcuate cross section and symmetrical about the width center. (7) The constant velocity universal joint according to claim 2, 3, 4, 5, or 6, wherein a cylindrical portion is formed in the axial center of the inner diameter surface of the retainer. (8) The constant velocity universal joint according to claim 7, wherein the diameter of the cylindrical portion is larger than the diameter of the outer diameter surface of the inner member. (9) The constant velocity universal joint according to claim 7, wherein the diameter of the cylindrical portion is equal to the diameter of the outer diameter surface of the inner member.
