A fuel tank for an automobile has a separator film to separate the inside of a fuel storage container of the fuel storing device into a fuel storage part and a space. The separator film is movable with a surface of liquid fuel in the fuel storage part. A filler pipe is connected to the fuel storage part. The filler pipe has a nozzle seal that seals a gap with respect to a refueling nozzle inserted into the filler pipe. A conduit communicates a part of the filler pipe adjacent to the nozzle seal with an upper part of the fuel storage part. A closure preventing means prevents the separator film from closing an opening of the conduit at the upper part of the fuel storage part. The closure preventing means prevents a negative pressure from being produced around the refueling nozzle before the fuel storage container is fully filled with fuel. When the refueling nozzle has an automatic stopper, the closure preventing means lets the automatic stopper stop the supply of fuel in response to a negative pressure only after the fuel storage container is fully filled with fuel.
