PROBLEM TO BE SOLVED: To provide a constant velocity universal joint that can reduce sliding resistance at a portion in contact with a torque transmission member.SOLUTION: Inner torque transmission surfaces 11 are formed in a plurality of places in the circumferential direction of an outer peripheral surface of an inner joint member 1, and a plurality of outer torque transmission surfaces 21 opposed to the respective inner torque transmission surfaces 11 are formed on an inner peripheral surface of an outer joint member 2. Torque transmission members 3 are arranged between the inner torque transmission surfaces 11 of the inner joint member 1 and the outer torque transmission surfaces 21 of the outer joint member 2, and inner side surfaces 3a and outer side surfaces 3b of the torque transmission members 3 are brought into contact with the inner torque transmission surfaces 11 and the outer torque transmission surfaces 21 respectively. The outer torque transmission surfaces 21 are formed as curved surfaces. |
