PROBLEM TO BE SOLVED: To surely detect the abnormality of any one of charging valves 16 upon disinfecting a charging machine. SOLUTION: Respective branch pipes 10 branched via an upper manifold 8 have charging mechanisms 12, each of which has the charging valve 16 for opening and closing a channel leading to a charging nozzle 18. A cleaning cup 44 is placed under each charging nozzle 18 to be fitted on it for disinfection or removed from it, and is connected to a lower manifold 46. A temperature detecting means 34 is arranged in a position that is near and slightly upstream to the charging valve 16, where the detecting means is not exposed inside the channel. The detecting means 34 is dewed with water, which prevents its temperature increase, when any of the charging valves 16 fails and does not open upon executing a vapor disinfection, thus makes it possible to detect the abnormality of any of the charging valves 16.
