Vibration-preventing device for a door in a vehicle

Abstract

The present invention is structured so that a guide pin will be captured within holes disposed on opposite walls of a case. A stopper wedge piece having a contact surface rides on the guide pin at one end of the case while a spring is disposed on the guide pin at the other end of the case. The guide pin has a collar close to one end that prevents the spring from slipping off that end of the guide pin. The collar also prevents the guide pin from passing through the hole at that end of the case. The spring keeps the stopper wedge pressed toward one side of the case while at the same time keeps the guide pin collar pressed toward the other side of the case. A metal plate pressed into the bottom of the case prevents wear of the case as the stopper wedge rides against the bottom plate during use. Assembly is facilitated by a downward incline toward the outside is formed on the lower portion of the hole on the case wall into which the stopper end of the guide pin is inserted. The steps of assembly include first pressing the bottom liner plate into the case. Second, slide the spring onto the stopper end of the guide pin until it contacts the collar. Third, slide the stopper wedge onto the guide pin, compressing the spring. Fourth, insert the stopper end of the guide pin through the hole at the stopper end of the case beyond its final position, taking advantage of the outward bevel to insert the guide pin at an incline. Finally, swing the collar end of the guide pin into alignment with the opposite hole, and allow the spring to urge the end of the guide pin into the hole until the collar contacts the wall of the case.
