Summary:PURPOSE: A rear suspension system of a vehicle is provided to reduce the impact force to be given to a vehicle body to a minimum through absorbing of impact force by the stopper bracket and to improve the riding comfort. CONSTITUTION: A rear suspension system of a vehicle includes a stopper bracket(10) to be bumped against a shock-absorbing member and composed of a first stopper bracket(11) and a second stopper bracket(12). The first stopper bracket is formed into closed section as a flat plate of fixed thickness and the top of the first stopper bracket is connected to a side member and a part of the bottom to connected to the shock-absorbing member is open. The second stopper bracket is installed to be able to shut the opening(11a) of the first stopper bracket and connected to the first stopper bracket by plural elastic members(20), and absorbs impact force while elastically contracting and being restored towards the side member when the stopper is bumped against the shock-absorbing member. 본 발명은 자동차의 리어현가장치에 관한 것으로, 사이드멤버(1)에 접합되어 리이프스프링(2)의 범프시 충격흡수부재(3)와 충돌되는 스톱퍼브라켓트(10)가, 일정두께를 갖춘 평판이면서 양쪽부위가 다수번 절곡되어 박스폐단면의 모양으로 형성됨은 물론 윗면은 상기 사이드멤버(1)에 접합되고 상기 충격흡수부재(3)와 종축상으로 연결되는 아랫면의 소정부위가 개구된 모양을 갖추도록 형성된 제1스톱퍼브라켓트(11)와, 이 제1스톱퍼브라켓트(11)의 개구부(11a)를 밀폐시키도록 안착됨은 물론 다수개의 탄성부재(20)를 매개로 상기 제1스톱퍼브라켓트(11)와 결합되어 충격흡수부재(3)와의 충돌시 상기 사이드멤버(1)방향으로 탄력적으로 압축되고 복원되면서 충격력을 흡수시키도록 된 제2스톱퍼브라켓트(12)로 이루어져, 상기 충격흡수부재(3)와 충돌시 그 충격력을 자체적으로 차체적으로 흡수하게 됨으로써 차체로 전달되는 충격력이 최소화되면서 탑승자의 승차감이 향상되도록 된 것이다.
