Abstract
A joint assembly has a pair of constant velocity universal joints and a connecting drive shaft. A cover unit protects the constant velocity universal joints and prevents hanging down of the joints under their own weight. The unit cover is arranged to cover the outer circumferential surfaces of the pair of constant velocity universal joints and boots. The unit cover is formed from elastomer material by injection molding. The cover unit inner circumferential surface has a configuration corresponding to the outline configurations of the pair of constant velocity universal joints and the boots.
