The vertical shaft fuel tank cap with charcoal canister includes a fuel tank inner cap and fuel tank outer cap. A hollow room with an upper opening is disposed in the center of the fuel tank inner cap. The fuel tank outer cap is disposed above the fuel tank inner cap. The ventilating cap is disposed in the hollow room and divides the hollow room into filling room and containing room. The air outlet leading the fuel vapor to the containing room is disposed on the bottom of the containing room. The air interstice leading fuel vapor from the containing room to the filling room is disposed between the outer walls of the ventilating cap and inter wall of the containing room. The fuel-absorption substrate is disposed in the filling room. The filtering performance of charcoal powder can be enhanced since it is exempted from long-time fuel soaking.
