Patent Images
1. A ball joint comprising:
- a synthetic resin housing having an opening at the top;
a concave spherical surface extending from the opening;
a ball stud comprising a ball head and a stud part, wherein the ball head is pivotally fixed within said concave spherical surface and the stud part projects through the opening;
a circular concave step formed in the synthetic resin housing proximate to the outer edge of the opening; and
a metal ring fixed within the circular concave step.

Abstract
A synthetic with an opening at the top and a concave spherical surface extending from the opening, where a ball head of a ball stud is fixed, has a circular concave step on the outer surface of the housing surround the opening. A metal ring is fixed on the circular step so that the strength of the opening of the synthetic resin housing in a radial inward direction is greatly increased to resist the pull-out load on the ball stud. Warping of the opening is thereby prevented.
