The present invention relates to a subframe coupling device of a vehicle which has a configuration of coupling a subframe (1) to a vehicle body (2) by using a bolt member (10), a washer member (20) formed in a truss structure, and a nut member (30). The present invention can increase rigidity (strength) of an input point of a portion where the bolt member (10) and the nut member (30) are coupled through a plurality of washer members (20) vertically stacked. Moreover, the present invention can guide separation of the bolt member (10) through breakage of the washer member (20) when a collision accident occurs and can minimize transmission of an impact amount toward a passenger through the subframe (1) by separation of the bolt member (10).

    본 발명은 차량의 서브프레임 결합장치에 관한 것으로, 볼트부재(10)와 트러스 구조로 형성된 와셔부재(20) 및 너트부재(30)를 이용해서 서브프레임(1)을 차체(2)에 결합할 수 있는 구성으로, 상하로 적층된 복수개의 와셔부재(20)를 통해 볼트부재(10)와 너트부재(30)가 결합된 부위의 입력점 강성(강도)를 증대시킬 수 있으며, 충돌사고 발생시 와셔부재(20)의 파단을 통해 볼트부재(10)의 이탈을 유도할 수 있고, 볼트부재(10)의 이탈을 통해 서브프레임(1)을 통한 승객쪽으로의 충격량 전달을 최소화할 수 있도록 된 것이다.
