An automobile having a leak fuel gas discharging structure for discharging a compressed fuel gas, leaking from a fuel tank disposed in a space below a floor panel of the automobile, outside the automobile, said leak fuel gas discharging structure comprising:

• a wheel house having an internal space formed therein;
• a hollow reinforcement member extending between the floor panel and the wheel house and having a hollow channel interconnecting the space below the floor panel and the internal space of the wheel house;
• a body panel disposed on an exterior side of the wheel house and having a filler recess formed therein;
• a filler lid attached to the body panel so as to open and close the filler recess, the filler recess being normally closed by the filler lid with a clearance defined between a peripheral edge of the filler recess and a peripheral edge of the filler lid;
• the wheel house having a portion corresponding in position to the filler recess and having an opening formed therein, said opening interconnecting the filler recess and the internal space of the wheel house;
• and
• the hollow channel, the internal space, the filler recess and the clearance together forming a continuous leak fuel gas discharge passageway extending from the space to the outside of the body panel thereby to allow the leak fuel gas to flow outside the automobile through the passageway.
