PROBLEM TO BE SOLVED: To provide a fuel tank that can store a plurality of kinds of fuel and prevent mixing of the plurality of kinds of fuel without increasing a maximum capacity of the tank.SOLUTION: A fuel tank 1 includes a movable membrane 6. The movable membrane 6 is provided to spread from an upper wall 13 to a lower wall 14 inside a tank body 3, at least a part of the movable membrane 6 has flexibility and can be moved according to a first fuel 7 stored in a first space 4 or a second fuel stored in a second space 5. This allows the tank to sufficiently store each fuel 7 without increasing the maximum capacity of the tank unnecessarily. In addition, such movable membrane 6 allows the first fuel 7 to be stored in the first space 4 and the second fuel to be stored in the second space 5. In short, the respective fuel 7 can be water-tightly divided into separate spaces to thereby prevent mixing of the respective fuel 7 without storing the fuel in separate dedicated tanks. |
