When the temperature detection unit 20 detects that the temperature of the filling gas in the gas filling device is within this normal temperature range, the green flash light flashes, and the yellow flash light 506 and the red flash light 507 are turned off.

[0058] The critical temperature range is 15-20° C., excluding the endpoint value. When the temperature detection unit 20 detects that the temperature of the filling gas in the gas filling device is within this critical temperature range, the yellow flash light 506 flashes, and the green flash light and the red flash light 507 are turned off.

[0059] When the temperature detection unit 20 detects that the temperature of the filling gas in the gas filling equipment is lower than the lowest value in the critical temperature range, that is, equal to or lower than 15°C, the red flash light 507 flashes, the yellow flash light 506 and the green flash light are turned off, and an alarm sound is played through a pair of speakers 510.
