To solve the problem that, in a refueling device having a plurality of refueling routes, a refueling nozzle for a wrong kind of fuel oil could be put into an oil filler port by mistake.

In a refueling device 1 the refueling nozzles 3A-3C have nozzle lamps 10A-10C using LED(light-emitting diode) respectively. A controller controls the refueling according to a refueling mode (full-tank mode or preset mode) set by controlling a manipulation panel 12 of a setting apparatus 11. The controller lights one of the nozzle lamps 10A-10C corresponding to the kind of fuel oil set for by the control of the manipulation panel 12 of the setting apparatus 11, whereas when a refueling nozzle 3A-3C for a kind of fuel oil other than the kind set for is taken off the hanger, the controller turns on and off the nozzle lamp 10A-10C of the wrong refueling nozzle 3A-3C. Therefore the supply of oil differing in kind from the oil set for can be prevented.
