Bottom structure of the vehicle comprises a tunnel part, a forward part of the bottom, an inclined part, a rear part of the bottom and a pair of reinforcing elements of the bottom part. Tunnel part is located in the central part of the vehicle in the direction of its movement. Front part of the bottom passes on both sides of the tunnel part. Inclined part is formed continuously with the rear end of the tunnel part and the rear end of the front part of the bottom. Rear part of the bottom passes back from the inclined part. Reinforcing elements of the lower part are connected to the lower surface of the region, which continuously extends from the tunnel part to the front part of the bottom. Distance between the reinforcing elements of the lower part in the width direction of the vehicle gradually decreases as the reinforcing elements of the lower part become closer to the inclined portion.
