To provide a liquid fuel tank capable of easily and certainly injecting a liquid fuel while remaining a sufficient air space.SOLUTION: The liquid fuel tank includes a tank body that has an opening portion at an upper part and can collect a liquid fuel, and a partitioning wall portion that is provided so as to turn an upper end toward the opening portion, and divides an inner space of the tank body into a first chamber and a second chamber. The partitioning wall portion is formed with a communication hole communicates the first chamber and the second chamber so as to make the liquid fuel flow from the first chamber to the second chamber when injecting the liquid fuel from the opening portion to the first chamber. The communication hole is provided so as to make a liquid surface of the liquid fuel in the second chamber position lower than a liquid surface of the liquid fuel in the first chamber when injecting the liquid fuel into the first chamber. The communication hole is preferably provided at a lower part of the partitioning wall portion. An opening hole area of the communication hole is preferably smaller than an area of the upper opening of the first chamber.SELECTED DRAWING: Figure 1

    【課題】本発明は、十分な空気空間を残した状態で液体燃料を容易かつ確実に注入することができる液体燃料用タンクの提供を課題とする。【解決手段】本発明に係る液体燃料用タンクは、上部に開口部を有し、液体燃料を貯留可能なタンク本体、及び上端が上記開口部に向けて設けられ、上記タンク本体の内部空間を第1室と第2室とに区画する隔壁部を備え、上記隔壁部に、上記開口部から上記第1室への液体燃料の注入時に上記第1室から上記第2室へ液体燃料が流入するように上記第1室及び上記第2室を連通する連通孔が形成され、上記第1室への液体燃料の注入時に上記第2室内の液体燃料の液面が上記第1室内の液体燃料の液面より低く位置するように、上記連通孔が設けられている。上記連通孔は、上記隔壁部の下部に設けられているとよい。上記連通孔の開孔面積が、上記第1室の上部開口の面積より小さいとよい。【選択図】図1
