Abstract

A vehicle floor lower structure includes: a floor panel configuring a floor of a vehicle and formed with a floor tunnel, that projects out toward a vehicle body upper side and extends along a vehicle body front-rear direction, the floor tunnel is disposed at a vehicle width direction center of the floor panel; a fuel tank that is disposed at a vehicle body lower side of the floor panel and that includes a main tank section disposed inside the floor tunnel and an extension tank section that is disposed inside the floor tunnel and that projects out from the main tank section toward a vehicle body front side or a vehicle body rear side; and an exhaust pipe that is routed so as to pass by inside the floor tunnel at a vehicle width direction outer side of the main tank section and the extension tank section,

Claims

1. A vehicle floor lower structure comprising:

a floor panel configuring a floor of a vehicle and formed with a floor tunnel, that projects out toward a vehicle body upper side and extends along a vehicle body front-rear direction, the floor tunnel is disposed at a vehicle width direction center of the floor panel;

a fuel tank that is disposed at a vehicle body lower side of the floor panel and that includes a main tank section disposed inside the floor tunnel and an extension tank section that is disposed inside the floor tunnel and that projects out from the main tank section toward a vehicle body front side or a vehicle body rear side; and

an exhaust pipe that is configured to extend from an engine and that is routed so as to pass by inside the floor tunnel at a vehicle width direction outer side of the main tank section and the extension tank section.

2. The vehicle floor lower structure of claim 1, wherein:

the fuel tank includes a sub tank section projecting out from the main tank section toward a first side in the vehicle width direction outer sides of the main tank section; and

the exhaust pipe is routed so as to pass by at a second side in the vehicle width direction outer sides of the main tank section.
