Abstract
A fuel tank T has a seal member,provided at a fuel entry port,provided at an upper end of a filler pipe,extending continuously to a tank main body,for sealing the outer circumference of a nozzle of a fuel filling gun G. A first relief valve,and a second relief valve,which are adapted to open when the internal pressure of the filler pipe,reaches or exceeds a predetermined value are provided along a first relief passage,and a second relief passage,, respectively, which continuously extend to the filler pipe,. When excessive fuelling occurs, the first relief valve,is made to open so that fuel inside the filler pipe,is allowed to be discharged to the outside thereof, and the second relief valve,is made to open so that part of fuel inside the filler pipe,is allowed to flow out into the fuel entry port,located above the seal member so as to inform the operator of a fuel filling pump of the occurrence of an abnormal situation to thereby prompt him or her to stop fueling.
