Abstract
A fuel tank includes a vent cutout valve having a first chamber connected to a vent tube, a second chamber communicating with a canister and a third chamber connected to an evaporation tube. The first and second chambers are defined by a first partition wall with a first communication bore and the second and third chambers are defined by a second partition wall with a second communication bore. A main body of the vent cutout valve is disposed within the second chamber to open the first communication bore when a shutter presses the main body of the vent cutout valve, and is provided with a check valve to close the second communication bore which is biased toward the second partition wall by a resilient member interposed between the check valve and the valve main body of the vent cutout valve.
