Claims

[Scope of utility model registration request]

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 housing disposed outside the fuel injection flow path and communicating with the fuel injection flow path; a valve body housed in the housing; the valve body and the slide portion; an elongated flexible body that connects the valve body, a biasing unit that applies a biasing force to the valve body so that the slide portion slides in the extraction direction, and communication between the inside of the housing and the fuel vapor recovery unit. and 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 path that communicates with the inside of the housing and the fuel tank. A fuel vapor emission prevention device comprising: a vapor guide path;
