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 circumferential surface of the outer member and the outer circumferential surface of the inner member and holds the ball. A constant velocity universal joint in which the cage surface is made of a material with a low coefficient of friction. (2) The constant velocity universal joint according to claim 1, wherein the cage is made of a sintered oil-impregnated alloy. (3) The constant velocity universal joint according to claim 1, wherein the retainer has ceramic coating layers on its inner and outer peripheral surfaces. (4) The constant velocity universal joint according to claim 1, wherein the retainer has a solid lubricant coating layer on its inner and outer peripheral surfaces. (5) The constant velocity universal joint according to claim 1, wherein the retainer is made of a porous ceramic material impregnated with oil or fat. (6) An outer member with an axial guide groove formed on its inner circumferential surface, an inner member with an axial guide groove formed on its outer circumferential surface, and between the guide groove of the outer member and the guide groove of the inner member. and a retainer that holds the ball between the inner circumferential surface of the outer member and the outer circumferential surface of the inner member, and at least one of the contact portions of the above-mentioned components. A constant velocity universal joint with a surface treatment layer made of carbide, nitride, or a metal composite such as molybdenum or tungsten and having a hardness of HRC63 or higher. (7) Claim in which the ball is made of ceramics (
6) Constant velocity universal joint.
