    TECHNICAL FIELD
    [001] The present invention relates to a saddle-type vehicle, including motorcycle and similar vehicles. BACKGROUND OF THE INVENTION
    [002] In the current trend to improve environmental behavior, vehicles equipped with saddles that contain a container for recovering the fuel evaporated in a fuel tank have become popular.
    [003] The container is connected to a charging hose to recover the evaporated fuel in the fuel tank and supply the container with the evaporated fuel. In addition, the container is connected to a purge hose, an air introduction tube, and a drain tube. When evaporated fuel is purged, an air introduction tube introduces air (atmospheric pressure) into the container. The bleed hose supplies an engine inlet system with air introduced through the air inlet tube and a mixture of fuel evaporated from the air absorbed by the container. The drain tube externally releases excess water and similar substances.
    [004] In addition, the saddle-type vehicle has a drain pipe to release the fuel externally when it overflows through the fuel supply opening in the fuel tank or when it splashes on the periphery of the fuel supply opening in refueling.
    [005] As a result, the saddle-type vehicle requires a drain pipe for a container and a drain pipe for a fuel tank. The connection scheme of the respective drain pipes becomes complex.
    [006] For example, PATENT DOCUMENT 1 discloses a configuration in which an oil port is arranged in the vicinity of a fuel supply opening, simultaneously, a tray is provided on the periphery of the fuel supply opening and the oil port , and the excess liquid from each port accumulates in the tray and is released externally through a container. DESCRIPTION OF RELATED ARTPATENT CUMENT PATENT DOCUMENT 1Japanese Patent No.4135431 SUMMARY OF THE INVENTION PROBLEM TO BE SOLVED BY THE INVENTION
    [007] However, the configuration in accordance with PATENT DOCUMENT 1 mentioned above, excess liquid from the fuel supply opening and the oil port, namely, fuel and lubricating oil are fed into the container. It would be preferable for the container to draw in external air without steam in order to efficiently separate the fuel absorbed by the container.
    [008] In addition, the fuel supply opening and the oil port must remain in close proximity relationship in the conventional technique mentioned above. As a result, the fuel tank and the oil tank are arranged adjacently. As a result, the oil tank takes up the space for supplying the fuel tank, which tends to influence the capacity of the fuel tank. The application of the techniques mentioned above in PATENT DOCUMENT 1 allows the adjacent disposition of the fuel tank and the container.
