とする燃料蒸気排出防止装置用フロート構造。 Used in a fuel vapor emission prevention device that collects fuel vapor generated during refueling and prevents the fuel vapor from being discharged outside the vehicle, and communicates the upper side of the fuel tank with the fuel vapor recovery section that collects the fuel vapor. This is a float structure for a fuel vapor discharge prevention device to prevent fuel from flowing into piping, which has a hollow shape and floats on the fuel liquid surface due to buoyancy, and a float body that is housed and has a structure that controls the amount of fuel. A guide portion that guides the float body to a position where fuel flows into the pipe inlet is blocked and an open position is provided in the float body so that a hollow portion of the float body communicates with the inside of the fuel tank. a plurality of holes, one part of which is located below the fuel liquid level and the other part of which is located above the fuel liquid level so that the fuel can flow into and be discharged from the hollow part. Float structure for discharge prevention device.
