  • Synthetic resin ball joint with reinforcing rib
    Patent number: 5352059
    Abstract: A synthetic resin connecting rod is disclosed having a ball socket integrally formed with an opening on one side and a concave spherical surface extending from the opening at each end of the rod. In order to increase the strength, the connecting rod has a rib as a reinforcement on the connecting line between the centers of each spherical surface, the connecting line intersecting a transverse cross section of the rib. A ball joint using the preferred synthetic resin connecting rod is lighter than one using a metal rod and is strong enough to be used as a ball joint for a stabilizer in an automobile.
