사이드실(500)에는 잭업시의 강성확보를 위해 잭업보강재(502)가 설치되어 있고, 사이드실(500)과 일정 거리 이격되어 평행하게 배치된 리어플로어사이드멤버(504)와 사이드실(500) 사이는 사이드실서포트(506)로 연결되어 있는 구조이다.The side seal 500 is provided with a jack up reinforcement 502 for securing rigidity during jack up, and the rear floor side member 504 and the side seal 500 disposed in parallel with the side seal 500 at a predetermined distance. The structure is connected to the side seal support 506.

상기 잭업보강재(502)는 잭업시 상기 사이드실(500)의 하측에서 작동되는 잭(JACK)으로부터 가해지는 집중하중을 지탱하도록 하는 역할을 하며, 상기 사이드실서포트(506)는 상기 리어플로어사이드멤버(504)와 사이드실(500)을 구조적으로 연결하여 차량의 충면충돌시에 충돌에너지를 흡수할 수 있도록 되어 있다.The jack up stiffener 502 serves to support the concentrated load applied from the jack (JACK) that is operated at the lower side of the side seal 500 during jack up, the side seal support 506 is the rear floor member 504 and the side chamber 500 are structurally connected so that collision energy can be absorbed during the collision of the vehicle.
