PROBLEM TO BE SOLVED: To provide a fueling system that uses a fueling device of a gas station during power failure, prevents deformation of an input shaft or the like of a pump, and properly transmits torque.SOLUTION: An emergency pumping device of a gas station is connected, during power failure, to a fueling device 1 for pumping up fuel oil in an underground tank by electric power and discharging it from a fueling nozzle 10. The fueling device 1 has: a pump 12P having an input shaft and a driven pulley 12 fixed to the input shaft, and pumping up the fuel oil in the underground tank; a motor 11M having an output shaft and a driving pulley fixed to the output shaft, and driving the pump 12P; and a belt 14 connecting the driving pulley and the driven pulley 12. The emergency pumping device includes a flexible shaft 3 in which a bending shaft is wrapped in an outer cylinder and the bending shaft is connected to the input shaft from which the driven pulley 12 is removed, and a manpower device 2 to be driven by manpower to apply torque to the bending shaft. |
