クのエバポ装置。 The upper space of the fuel tank is electrically connected to the canister via a check valve by a conduit, and one side of the canister is electrically connected to the intake manifold of the engine via a conduit, so that the fuel vapor generated in the fuel tank is transferred to the canister. In the fuel tank evaporation device, the other side of the canister is electrically connected to an air cleaner through a conduit, and the fuel vapor in the canister is stored in the canister and is configured to lead the fuel vapor in the canister to the intake manifold through the conduit when the engine is operated. An electric fan is provided in the conduit between the fuel tank and the air cleaner, and the electric fan is configured to be operated by a switch that opens and closes depending on the open/close state of the fuel inlet of the fuel tank and the state of the amount of fuel injected into the fuel tank, When the fuel injection port is opened to inject fuel, and until the fuel tank is filled with fuel, the switches open and close to operate the electric fan, and the fuel vapor in the fuel tank is filled. A fuel tank evaporation device characterized in that air is forcibly guided from the other side of the canister to an air cleaner through a conduit.
