Abstract
A leak fuel gas discharging structure for an automobile includes a hollow reinforcement member extending between a floor panel and a wheel house and interconnecting an underfloor space and an internal space of the wheel house. The wheel house has a portion facing a filler recess and having an opening which through which the filler recess and the internal space of the wheel house are connected together. The filler recess is normally closed by a filler lid with a clearance defined between a peripheral edge of the filler lid and a peripheral edge of the filler recess. By the structure thus arranged, a fuel gas, leaking from a fuel tank disposed in the underfloor space, is discharged outside the vehicle body.
