Abstract: A vehicle-body structure which prevent deformation of a floor tunnel caused by a side collision load transmitted from a cross member to the floor tunnel via a seat mounting bracket. A pair of left and right backbone frames extending in a vehicle front-rear direction are provided each of which faces a top and a side of a floor tunnel and is fixed to the floor tunnel. A tunnel reinforcement is provided that includes a front projection, an intermediate projection, and a rear projection abutting on an underside of the floor tunnel. The backbone frame includes multiple beads abutting on the floor tunnel. The tunnel reinforcement is fixed at the front projection, the intermediate projection, and the rear projection to the seat mounting bracket via the floor tunnel and is also fixed to the multiple beads of the backbone frame via the floor tunnel.

Abstract: A vehicle underbody structure includes a catalyst disposed in a front portion of an exhaust pipe; a cover member for covering the catalyst from above; and a heat insulator disposed inside a tunnel portion behind the catalyst and configured to cover the exhaust pipe from above. The heat insulator is disposed away from the tunnel portion by a predetermined gap in an up-down direction. A front portion of the heat insulator and a rear portion of the cover member are disposed in such a way as to overlap each other. A front end of the heat insulator is disposed on the upper side with respect to a rear end of the cover member.
