PROBLEM TO BE SOLVED: To lock a sawtooth-like latch on an arbitrary site of a spiral in a filler opening when an insertion cylinder for refueling is inserted into the filler opening of a gas container to prevent a pump nozzle from accidentally dropping from the filler opening by forming the sawtooth-like latch on an outer periphery of the insertion cylinder of the pump nozzle. SOLUTION: A pump nozzle 4' with a trigger includes a refueling insertion cylinder 415' formed with a sawtooth-like latch 411 on an outer periphery and a trigger 70. At the time of refueling with the pump nozzle 4', after the insertion cylinder 415' is inserted into a filler opening of a vehicle or the like, the trigger 70 is activated to start feeding, and the nozzle is left untouched. While the nozzle is left untouched, since the sawtooth-like latch 411 is locked in a spiral on an internal face of the filler opening, the nozzle can be prevented from accidentally dropping from the filler opening, so that safe refueling is realized. In addition, a nozzle insertion sensor is provided in the vicinity of a foot of the insertion cylinder 415', and the nozzle insertion sensor can sense that the pump nozzle 4' has been correctly set in the filler opening.
