Abstract
A lower wall partially defining a fuel storing chamber of a fuel tank curves upward in accordance a decrease in an amount of fuel stored in the fuel storing chamber. The volume of a gaseous space in the fuel storing chamber is reduced, in comparison with a fuel tank in which a lower wall does not deform, by an amount corresponding to a reduction of the volume of the fuel storing chamber achieved by the curvature of the lower wall. An amount of fuel not discharged from the fuel storing chamber via a fuel passage but remaining near a peripheral end portion of the lower wall of the fuel storing chamber due to the upward curvature of the lower wall is discharged via a residual fuel discharging pipe, so that the residual fuel amount of the fuel storing chamber is minimized.
