PROBLEM TO BE SOLVED: To suppress the bearing pressure of a torque transmission surface on retaining windows of a retainer. SOLUTION: A first constant velocity joint 10a and a second constant velocity joint 10b each comprise an input shaft side member 12 having first guide grooves 32a-32f, an output shaft side member 14 having second guide grooves 38a-38f intersecting the first guide grooves 32a-32f, the retainer 16 having the plurality of retaining windows 18, and balls 20 rollingly arranged between each of the first guide grooves 32a-32f and each of the second guide grooves 38a-38f for transmitting torque. The first guide grooves 32a-32f and second guide grooves 38a-38f of the first constant velocity joint 10a and the first guide grooves 32a-32f and second guide grooves 38a-38f of the second constant velocity joint 10b are arranged in reversed relation to be mutually line-symmetric in view from the input side.
