PROBLEM TO BE SOLVED: To provide a vehicle underfloor structure that can inhibit a piping shape of an exhaust pipe from becoming complicated while suppressing reduction of a capacity of a fuel tank.SOLUTION: A vehicle underfloor structure 10 includes: a floor panel that has a floor tunnel formed at a center of a vehicle width direction to protrude to a vehicle body upper side and extend in a vehicle longitudinal direction and constitutes a floor of a vehicle; a fuel tank 20 that has a main tank portion 22 disposed on the vehicle body lower side of the floor panel and disposed in the floor tunnel and an extended tank portion 23 protruded from the main tank portion 22 to the vehicle body rear side and disposed in the floor tunnel; and an exhaust pipe 40 extended from an engine 16 and arranged to pass through the vehicle width direction outer sides of the main tank portion 22 and the extended tank portion 23 in the floor tunnel.SELECTED DRAWING: Figure 4
【課題】燃料タンクの容量低減を抑制しつつ排気管の配管形状が複雑化されるのを抑制できる車両床下構造を得る。【解決手段】車体上方側へ突出し、かつ車体前後方向に延在するフロアトンネルが車幅方向中央に形成され、車両の床を構成するフロアパネルと、フロアパネルの車体下方側に配置され、フロアトンネル内に配置されるメインタンク部22と、メインタンク部22から車体後方側へ突出され、フロアトンネル内に配置される延長タンク部23と、を有する燃料タンク20と、エンジン16から延在され、フロアトンネル内におけるメインタンク部22及び延長タンク部23の車幅方向外側を通るように配管された排気管40と、を備えた車両床下構造10とする。【選択図】図4
