Abstract

Provided is a constant velocity universal joint of which the working efficiency of the assembling work can be improved and which can be manufactured at a low cost. Bag bodies (12) each of which is filled with a lubricant are contained in an outer ring (1) and a boot (7). The bag body (12) is made of a material which has a strength enough to prevent the lubricant from being discharged from the bag body due to its bursting or dissolving before or during assembling of the constant velocity universal joint and, after the bag body is contained in the joint, which allows the lubricant filled in the bag body to be discharged into the outer ring (1) by bursting of the bag body due to its contact with a part constituting the constant velocity universal joint caused when the constant velocity universal joint is operated or the entire or partial dissolving of the bag body by the lubricant.
