To provide an effective treatment structure for evaporative fuel gas flowing in a ventilation passage communicating a fuel tank and a canister, which uses supplied fuel.SOLUTION: A spiral metal pipe 2 fixed to the inner wall of a fuel supply pipe 3 is disposed in a ventilation passage communicating a fuel tank 4 and a canister 7. When fuel is supplied, supplied fuel 81 directly contacts with the spiral metal pipe 2, heat exchange between evaporative fuel gas 43 in the high-temperature fuel tank 4 and the low-temperature supplied fuel 81 is performed through the spiral metal pipe 2, the evaporative fuel gas 43 is cooled, then the saturated vapor pressure of the evaporative fuel gas 43 decreases, and thus an amount of the evaporative fuel gas 43 flowing out to the canister 7 can be reduced.SELECTED DRAWING: Figure 1

    【課題】給油燃料を利用した、燃料タンクとキャニスタとを連通する通気通路を流れる蒸発燃料ガスの効果的な処理構造を提供する。【解決手段】燃料タンク4とキャニスタ7とを連通する通気通路に燃料給油管3の内壁に固定される螺旋状金属管2を配設する。燃料給油時には、給油燃料81が、螺旋状金属管2に直接当たり、温度の高い燃料タンク4内の蒸発燃料ガス43と温度の低い給油燃料81間の熱交換が螺旋状金属管2を通して行われ、蒸発燃料ガス43が冷却され、蒸発燃料ガス43の飽和蒸気圧が下がり、キャニスタ7に流出する蒸発燃料ガス43の量を減らすことができる。【選択図】図1
