<p>A fuel tank (2) disposed on a floor (1) in a rear portion of a vehicle body is housed inside a housing box (4), which is provided with an upper portion thereof having a ventilation pipe (7) connected to the outside of a vehicle. Accordingly, leakage of fuel gas having a small molecular weight, does not affect the inside of a compartment because the fuel gas is discharged out of the vehicle through the ventilation pipe (7). In addition, the housing box (4) is separated into a lower box (5) and an upper box (6) to be fitted to the outside thereof. Therefore, an operation of inserting or detaching the fuel tank (2) is not interfered by detaching the upper box (6).</p> |
