する燃料タンク。 A switching valve is provided at the fuel tank injection port, which is normally closed and opened when the fuel injection nozzle is inserted.
One of the passages of the switching valve communicates with the fuel vapor adsorption canister and the other with the vapor outlet of the fuel tank via a first check valve, and the first check valve communicates with the vapor outlet of the fuel tank. It has a floating valve body that opens when the vapor pressure of the fuel is above a predetermined pressure and floats in the fuel liquid,
The floating valve body is configured to close a communication port with the switching valve by the inflow of a predetermined amount of liquid fuel into the first check valve, and the first check valve further includes: A second check valve that opens at a pressure greater than the internal pressure of the first check valve when the floating valve body closes the communication port is connected, and the second check valve opens its passage when opened. A fuel tank characterized in that it is configured to communicate with outside air.
