Kind Code:

Abstract:
A gas-liquid separation device with a check valve is provided in which, even if a liquid fuel flows towards the canister, the liquid fuel can be easily returned into the gas-liquid separation chamber. This gas-liquid separation device 10 with a check valve is arranged in a passage that connects a fuel cut-off device and a canister, and is for preventing liquid fuel that flows together with the fuel vapor from flowing towards the canister. The gas-liquid separation device has a casing 15, inside of which a gas-liquid separation chamber is formed, and a check valve 50. The casing 15 has a tank-side opening 28 which connects the fuel cut-off device and the gas-liquid separation chamber, and a canister-side opening 31 which connects the canister and the gas-liquid separation chamber. The check valve 50 has a connection pipe section 60 which is connected directly to the canister-side opening 31 and which constitutes part of the passage.
