The seal case 11 is filled with fuel. When the fuel pressure exceeds a predetermined adjustment pressure, the pressure regulator 20 is opened, and the fuel in the shell case 11 is returned to the fuel tank 2. Thereby, the pressure of the fuel supplied to the fuel pipe 3 side is appropriately adjusted. The fuel whose fuel pressure is adjusted is sent to the fuel pipe 3 through the oil chamber 19. The fuel pipe 3 is connected to the fuel injection valve of the engine as described above, and is sucked from the fuel tank 2 by the fuel supply device 1. The fuel is supplied to the fuel injection valve via the fuel pipe 3.
