ことを特徴とする蒸発燃料回収装置。[Claims for Utility Model Registration] A first communication pipe that communicates with the fuel tank, a second communication pipe that communicates with the fuel intake system, and a third communication pipe that is provided with an air opening are connected to each other. The atmosphere opening port of the third communication pipe of the charcoal canister is arranged in a closed space of the vehicle body, and due to the negative pressure of the fuel intake system, the fuel components accumulated in the charcoal canister are transferred to the charcoal canister. The vehicle is configured such that the fuel is sent to the intake system together with the atmosphere in the closed space obtained through a third communication pipe, further comprising a pressure-responsive valve that opens when the pressure in the third communication pipe becomes negative pressure. An evaporated fuel recovery device characterized in that an air intake part is provided outside the closed space and in the middle of the third communication pipe.
