An object of the present invention is to enhance the flexibility of design of a suction device, which sucks contents from a filling nozzle used for supplying hydrogen. The suction device (20) includes a first vacuum chamber (51), a vacuum pump (55) and a suction nozzle (100). The first vacuum chamber (51) is evacuated using the vacuum pump (55) in order to be prepared for water removal. Then, contents in the suction nozzle (100) are sucked by using the evacuated first vacuum chamber (51), thereby removing water from a filling nozzle (300). 본 발명의 과제는, 수소를 공급하기 위해 사용되는 충전 노즐의 내부를 흡인하는 흡인 장치에 대해, 설계의 자유도를 향상시키는 것이다. 흡인 장치(20)는 제1 진공 챔버(51)와, 진공 펌프(55)와, 흡인용 노즐(100)을 구비한다. 수분 제거의 준비로서, 진공 펌프(55)를 사용하여 제1 진공 챔버(51) 내를 진공화한다. 그 후, 진공화된 제1 진공 챔버(51)를 사용하여, 흡인용 노즐(100) 내를 흡인함으로써, 충전 노즐(300) 내의 수분을 제거한다.
