The fuel is delivered to the fuel tank through the filler pipe. The breather pipe includes a communicating passage, an opening, and at least one hole. The communicating passage connects the fuel tank to the filler pipe. The opening is provided at a first end of the breather pipe in the fuel tank. The opening is located below a predetermined fuel level in the fuel tank. The at least one hole is located above the predetermined fuel level in the fuel tank.
