PROBLEM TO BE SOLVED: To efficiently manufacture a constant velocity universal joint having preferable lubricating property, while preventing a solid lubricant from entering a portion that does not require the lubricant when filling the foaming solid lubricant in the constant velocity universal joint. SOLUTION: After filling the foaming solid lubricant 12 between an outer ring 2 and an inner ring 1 from an axial bore 7a of the inner ring 1 of the constant velocity universal joint, the axial bore 7a is plugged hermetically with a plug 14 and the solid lubricant 12 is foamed. Because the foaming solid lubricant 12 is foamed and hardened under such a condition that the plug 14 is attached, the solid lubricant flows into a portion with a cage hole or a track so that the space between the inner ring 1 and the outer ring 2 is fully filled with the lubricant, that is, the solid lubricant can be filled efficiently in the vicinity of a driving section of the constant velocity universal joint.
