Zusammenfassung:PROBLEM TO BE SOLVED: To provide a constant velocity joint that secures the retention property of grease in a slide part to thereby suppress fretting wear.SOLUTION: A constant velocity joint J includes: an outer race 1 having a ball rolling groove 1a on the inside surface thereof; an inner race 2 having a ball rolling groove 2a on the outside surface thereof; a ball 3 rolling in the ball rolling grooves 1a, 2a; a cage 4 preventing the ball 3 from being deviated from the ball rolling grooves 1a, 2a; and grease 5 filled between the outer race 1 and the inner race 2. In at least a part of the outside surface of the cage 4 and the inside surface of the cage 4, films 14a, 14b subjected to manganese phosphate processing are formed.
