PROBLEM TO BE SOLVED: To provide a vehicle fuel supply device capable of dispensing with active carbon and ensuring a simple structure.SOLUTION: A vehicle fuel supply device (10) comprises: a fuel tank (14) constituted by a flexible material that can expand and contract in proportion to a quantity of a liquid fuel (12) filled therein; and a gas storage vessel (32) constituted by a flexible material that can expand and contract in proportion to a quantity of gas (18) supplied inside. A gas supply pipe (31) contains a gas attraction device (33) attracting the gas (18) from within the fuel tank (14), and a purge pipe (35) that can purge the gas (18) and feed the gas (18) to an engine (71) is connected to the gas supply pipe (31). Liquid fuel infiltration prevention means (40) preventing the infiltration of the liquid fuel (12) into the gas storage vessel (32) is provided in a region between the fuel tank (14) and the gas attraction device (33) in the gas attraction device (33).

    【課題】活性炭が不要であり構造が簡便な車両の燃料供給装置を提供すること。【解決手段】車両の燃料供給装置(10)は、燃料タンク(14)が、充填された液体燃料(12)の量に合わせて膨張・収縮することが可能な可撓性材料によって構成され、気体貯留容器(32)が、内部に供給された気体(18)の量に合わせて膨張・収縮することが可能な可撓性材料によって構成されている。気体供給管(31)には、気体(18)を燃料タンク(14)内から吸引する気体吸引装置(33)が含まれていると共に、気体(18)をエンジン(71)にパージ可能なパージ管(35)が繋がれている。気体吸引装置(33)のなかの、燃料タンク(14)と気体吸引装置(33)との間の部位には、気体貯留容器(32)への液体燃料(12)の浸入を防止するための液体燃料浸入防止手段(40)が設けられている。【選択図】図1
