[0007] Also, in Patent Document 2 (Japanese Utility Model Laid-Open Publication No. 5-71083), the structure in which the fuel tank is set at the arched portion is disclosed, but such a structure cannot improve comfort and increase the fuel tank capacity. enlightenment
[0008] In addition, Patent Document 3 (Japanese Patent Laid-Open Publication No. Hei 5-155258) discloses a structure in which a fuel tank is formed along the back shape of the arched portion, and the fuel tank is arranged along the back face of the arched portion. However, adopting such a composition will make the structure of the fuel tank tend to be complicated, thereby reducing the realizability

Abstract

An underbody structure of a vehicle includes a floor panel (2-6) of which rear portion is raised to form a rear floor, a pair of left and right rear side frames (12,12) extending generally along a longitudinal axis of the vehicle at the rear of the floor panel (2-6) with a specific distance held between the left and right rear side frames (12,12) across the vehicle, and a rear cross member (14) extending widthwise across the vehicle and interconnecting forward end portions of the left and right rear side frames (12,12). A fuel tank (13) is mounted between the left and right rear side frames (12,12), and the rear cross member (14) is located under the floor panel (2) at the front of the fuel tank (13).

Description

technical field [0001] The present invention relates to a lower part of a vehicle in which a pair of left and right rear side beams extending in the front and rear direction of the vehicle are provided at a predetermined interval along the vehicle width direction behind a floor, and a fuel tank is provided between the pair of left and right rear side beams. Body structure. Background technique [0002] In the past, the underbody structure of the vehicle was generally as follows: Figure 16 structure shown. [0003] That is, the base plate 100 is connected to the rear base plate 102 through the arched portion 101 that rises upwards in a step shape at the rear, and a steering wheel is arranged at a position between the upper back of the arched portion 101 and the front lower portion of the rear base plate 102. A rear cross member 103 extending in the width direction has a fuel tank 104 provided behind the rear cross member 103 , and a rear seat 105...
