Disclosed is a vehicle body reinforcing structure. In the vehicle body reinforcing structure, a tunnel portion uplifted in a height direction of a vehicle in a floor panel forming the bottom surface of the vehicle body is provided, and an interior front end portion of a left and right seat cross member extended along the width direction of the vehicle is bonded on left and right both surface of the tunnel portion. In left and right both sides of a lower portion of the tunnel portion, a tunnel side member is bonded. A pipe nut is bonded through the left and right seat cross member and the left and right tunnel side member, respectively. The left and right both side pipe nuts are connected to each other via a reinforcing member such that distortion strength and impact responding performance of the vehicle body can be improved.

    차체 보강구조가 개시된다. 차체의 바닥면을 형성하는 플로어 패널에 차량의 높이 방향으로 융기된 터널부가 구비되고; 상기 터널부의 좌우 양측면에는 차량의 폭 방향을 따라 연장된 좌우 시트 크로스 멤버의 내측 선단부가 접합되며; 상기 터널부의 하부 좌우 양측에는 터널 사이드 멤버가 접합되고; 상기 좌우 시트 크로스 멤버와 상기 좌우 터널 사이드 멤버를 각각 관통해서 파이프 너트가 접합되고; 상기 좌우 양측의 파이프 너트는 보강부재에 의해 서로 연결되어, 차체의 비틀림 강성 및 충돌 대응 성능이 향상될 수 있다.
