To generate an adjusting function in a ball joint itself by utilizing an adjustor by setting it in a conventional ball joint so that the adjusting function of the ball joint and the adjusting function of the associated portions are interlocked and can be utilized, whereas the ball joint has only a role of a sliding function at a designated fulcrum, in an apparatus with the conventional ball joint set therein.
In a structure with the adjustor set between a housing part and a ball stud part of the conventional ball joint, the ball stud is set at an eccentric position of the adjustor with respective parts holdingly sliding, and the adjustor is arbitrarily rotationally moved. Rotational movement of the adjustor removes a position of the ball stud, thereby changing its fulcrum. The change of the fulcrum realizes the adjusting function. Connection to and utilization of the associated portions enable a further precise adjustment of the associated portions, thereby enabling to utilize a fixing-adjusting function of the associated portions as a variation-adjusting function in real time.
