A gas filling apparatus having a filling nozzle with high operability. A gas filling apparatus, comprising; a filling mechanism for transporting a gas from a gas supply source via a gas transporting pipe while measuring flow rate of the gas; a filling hoseconnected to the gas transporting pipe, the filling hose having a filling nozzleat an end; a nozzle hookon which the filling nozzle is hung; and a guide mechanismfor guiding the filling nozzle from the nozzle hook to a predetermined position when the filling nozzle is detached from the nozzle hook. The guide mechanism can guide the filling nozzle to a filling port of a fuel tank mounted on a vehicle, which allows the filling nozzle to move to the filling port of the fuel tank with ease even though the filling nozzle is heavy or a high pressure gas such as hydrogen gas is handled. The nozzle hook can include an injection portfor injecting a dry gas to the filling nozzle hung on the nozzle hook.

Gas filling apparatus

To provide a gas filling apparatus with high handleability and safety. A gas filling apparatus including: a filling mechanism for carrying a gas through gas carrying pipes while measuring flow rate of the gas from a gas supply source (accumulator); a filling hose connected to the gas carrying pipe and having a filling nozzle at an end of the filling hose; and an attachment sensor (nozzle attachment detecting portion) for outputting a detection signal after detecting that the filling nozzle is attached to a filling port of an in-vehicle tank, wherein filling gas to the in-vehicle tank by the filling mechanism becomes possible after the detection signal is inputted to the filling mechanism from the attachment sensor. The gas filling apparatus may further include: a pressure gauge for measuring a pressure in the in-vehicle tank; a thermometer for measuring ambient temperature; and a target pressure calculating means (comparing means) for calculating a pressure in the in-vehicle tank when filling up the in-vehicle tank or filling preset amount of the gas is finished before filling gas to the in-vehicle tank based on a capacity of the in-vehicle tank and the measured pressure in the in-vehicle tank and the measured ambient temperature; wherein the filling mechanism stops carrying the gas to the in-vehicle tank when the pressure in the in-vehicle tank reaches the target pressure.
