  • Ball joint
    Patent number: 5683196
    Abstract: A flange portion of a ball stud includes a seat surface which abuts a junction face of a concurrent rotation prevention plate. By ensuring that the contact face of the concurrent rotation prevention plate has a larger area than an area of the seat surface of the flange portion of the ball stud, the frictional force between an attached item and the contact face of the concurrent rotation prevention plate is greater than a rotational force applied to the ball stud when a nut is affixed to the ball stud. The ball stud is thus prevented from concurrently turning with the nut during a tightening or loosening operation.
