To provide a hydrogen gas filling device which enables removal of moisture in a tip side portion of a filling nozzle, from which moisture should be removed, in a short time.SOLUTION: A filling nozzle 7 includes: a nozzle body 7A which is detachably connected to a filler port 30A of a filled tank 30; a conduit line 8 which is provided within the nozzle body 7A and in which a hydrogen gas circulates; and a recessed part 9 which is provided opening to the tip side of the nozzle body 7A. The recessed part 9 encloses a periphery of an opening 8A of the conduit line 8. A dispenser housing 4 is provided with a nozzle hook 31 on which the filling nozzle 7 hooks. The nozzle hook 31 is provided with a closing member 39 which closes the recessed part 9 when the filling nozzle 7 hooks. The closing member 39 is provided with a dry gas blowing port 47 which blows a dry gas to the recessed part 9 of the filling nozzle 7 while facing the opening 8A of the duct line 8 of the filling nozzle 7.SELECTED DRAWING: Figure 9 【課題】充填ノズルの先端側で水分を除去すべき部分の水分の除去を短時間で行うことができる水素ガス充填装置を提供する。【解決手段】充填ノズル７は、被充填タンク３０の充填口３０Ａに着脱可能に接続されるノズル本体７Ａと、ノズル本体７Ａ内に設けられ水素ガスが流通する管路８と、ノズル本体７Ａの先端側に開口して設けられた凹み部９とを備えている。凹み部９は、管路８の開口部８Ａの周囲を囲んでいる。ディスペンサ筐体４には、充填ノズル７を掛止めするノズル掛け３１が設けられている。ノズル掛け３１には、充填ノズル７を掛止めしたときに凹み部９を閉塞する閉塞部材３９が設けられている。閉塞部材３９には、充填ノズル７の管路８の開口部８Ａに対面した状態で、充填ノズル７の凹み部９に対して乾燥ガスを吹付ける乾燥ガス吹付け口４７が設けられている。【選択図】図９
