PURPOSE:To improve the safety and to prevent the atmospheric contamination by arranging a separator chamber having a vertical communication hole on the upper wall of tank body while providing a vapor pipe coupling between the liquid face in tank and the upper space of tank body in addition to the vapor discharge pipe. CONSTITUTION:Under horizontal state of body 1, the produced vapor will flow through second vapor pipe 12 and a communication hole 9 into a separator chamber 7A while vented through first vapor pipe 11 to the outside of tank body 1 and led through a lead-out tube 10 to a canister not shown. Even upon inclination of the liquid face as shown by the lines (a), (b) due to the inclination or turning of car, the opening 12a of second vapor pipe 12 and the separator chamber 7A are positioned higher than the liquid faces (a), (b) to prevent flow- out of fuel to the outside of tank thus to discharge the vapor to the outside of tank. With such arrangement, safety is improved while the atmospheric contamination is prevented. |
