PROBLEM TO BE SOLVED: To provide a piping connecting structure of a fuel vapor discharge prevention system which is simplified in a manufacturing process.SOLUTION: By using a seal member 84 as a seal member of a connecting part between a penetration pipe 46 and a connector 44 (opening part 74), and also as a valve body of a relief valve, the seal performance of a connecting portion between the penetration pipe 46 and the connector 44 can be secured without fusing the connecting portion, and the seal member is made to function as a relief valve. Accordingly, a manufacturing process of a piping connecting structure of a fuel vapor discharge prevention system 10 is simplified.SELECTED DRAWING: Figure 2

    【課題】製造工程が簡略化された燃料蒸気排出防止システムの配管接続構造を提供する。【解決手段】シール部材84を貫通管46とコネクタ44(開口部74)との接続部のシール部材として使用すると共に、リリーフ弁の弁体として使用することによって、接続部分を溶着することなく貫通管46とコネクタ44の接続部分のシール性を確保すると共に、リリーフ弁としても機能させることができる。したがって、燃料蒸気排出防止システム10の配管接続構造の製造工程が簡略化される。【選択図】図2
