ABSTRACT:
A ball joint of the present invention joins a pair of members so that relative pivotal movement of the pair of members is permitted. The ball joint comprises a ball stud to be connected to one of the pair of members, a bearing support rod to be connected to the other member, and a cup-shaped bearing for supporting the ball stud on the rod. The bearing is formed of an elastic polymeric material and has an expandable open end to permit the ball of the ball stud to be put in and taken out of a hollow defined by the spherical inner surface of the bearing through the open end. The opposite ends of a rod forming the bearing support rod is bent in a ring-shaped heads, respectively. When the bearing is fitted in the ring-shaped head, the ring-shaped head compresses the bearing so that the ball of the ball stud is unable to come off the bearing. The ball joint of the present invention comprises a comparatively small number of component parts and has a simple construction, and any expensive manufacturing facilities are not necessary for manufacturing and assembling the component parts.
