ABSTRACT:
A universal joint comprises an external cup-like element, and a part spherical head located in the element. Three balls are interposed between opposing surfaces of the head and the element and are engaged in pairs of grooves in the head and in the element. The balls are retained in slots in a cage. An auxiliary groove is formed in the external element adjacent one of the ball-receiving grooves and is spaced therefrom by a surface having a width less than that of the slots in the cage whereby this surface can be located in one of the slots during assembly of the joint to permit insertion of the cage into the external element.
