The present invention relates to a fuel tank system (10) to handle fuel vapor generated in a hybrid vehicle fuel tank (11), wherein a portion of a pipe (13) connecting a fuel tank and a canister is manufactured to be a pipe capable of being elastically deformed, and an elastically deformed pipe (17) is formed with a material of smaller strength or thickness than the pipe (13) connecting the fuel tank and the canister. Therefore, when pressure is transmitted to the fuel tank from the canister, the elastically deformed pipe (17) is expanded or contracted to absorb fuel vapor pressure.

    본 발명은 하이브리드 차량 연료 탱크(11)에서 발생되는 연료 증기를 처리하기 위하여 연료 탱크와 캐니스터를 연결하는 관(13)의 일부를 탄성 변형이 가능한 관으로 제작하되 탄성 변형관(17)은 연료 탱크와 캐니스터를 연결하는 관(13)보다 작은 강성의 재질 또는 두께로 이루어져 캐니스터에서 연료 탱크로 압력이 전달시 탄성 변형관(17)이 팽창 또는 수축하며 연료 증기 압력을 탄성 변형관(17)이 흡수하는 것을 특징으로 하는 연료 탱크 시스템(10)에 관한 것이다.
