とする燃料蒸気排出防止装置。 A fuel vapor exhaust system that communicates between a fuel vapor recovery section that recovers fuel vapor generated during refueling and the inside of the fuel tank, guides the fuel vapor to the fuel vapor recovery section, and prevents the fuel vapor from being discharged to the outside of the vehicle. The prevention device includes a fuel injection channel into which a fuel injector is inserted during refueling, and a fuel injection channel that is disposed in the fuel injection channel at a position that interferes with the insertion locus of the fuel injector along the insertion and removal direction. a sliding part that is slidable by the user; a biasing means that biases the sliding part in a direction in which the fuel injection part is removed; and a housing that is disposed outside the fuel injection passage and communicates with the fuel injection passage. a valve body housed in the housing and connected to the slide portion so as to slide together with the slide portion along the insertion and extraction directions; and a valve body that communicates between the inside of the housing and the fuel vapor recovery portion. a first fuel vapor guide path that is opened by the valve body during refueling and closed by the valve body when not refueled; and a second fuel vapor guide that communicates between the inside of the housing and the fuel tank. A fuel vapor emission prevention device comprising:
