  • the gas station 2 because of its structure, which has a small roof due to the above-described circumstances, even in a situation where it is easier for rain to enter into the filling position of the fuel gas for the gas fuel vehicle 1 , it is possible to avoid the adhesion of the receptacle 12 and the filling nozzle 23 due to freezing during the filling operations, and to fill a fuel gas into the gas fuel vehicle 1 smoothly. Therefore, even users who are not familiar with the filling operations can still easily carry out the filling operations of the fuel gas into the gas fuel vehicle 1 .
  • a drain pore 62 is formed at a position below the waterproof cover 61 , it is possible to flow water out from the drain pore 62 to the outside even when water penetrates into the waterproof cover 61 . Therefore, it is possible to avoid the risk of water accumulating in the waterproof cover 61 , adhering to the joint of the receptacle 12 and the filling nozzle 23 , and causing freezing.
  • the communication parts of the infrared communication devices 52 , 53 which communicate tank information are covered by the waterproof cover 61 , so it is possible to avoid the effect of disturbances and to perform infrared communications smoothly.
  • the waterproof cover 61 it is possible to make the waterproof cover 61 smaller than that of the case where a waterproof cover is provided on the side of the filling port 11 of the gas fuel vehicle 1 , allowing material costs to be reduced.
  • a sheet-like waterproof cover 72 is adhered to the upper edge of a filling port lid 71 which is mounted on the filling port 11 so that the filling port lid 71 is capable of being opened and closed.
  • This waterproof cover 72 is also adhered to the upper part of the filling port 11 and to the lateral part of the side facing the filling port lid 71 .
  • a fuel gas consisting of a hydrogen gas is sent out from the filing apparatus 21 of the gas station 2 at high pressure, cooled to about ⁇ 20° C. by the pre-cooler 24 , and then filled into the tank of the gas fuel vehicle 1 .
  • the gas station 2 because of its structure, which has a small roof due to the above-described circumstances, even in a situation where it is easier for rain to enter into the filling position of the fuel gas for the gas fuel vehicle 1 , it is possible to avoid the adhesion of the receptacle 12 and the filling nozzle 23 due to freezing during the filling operations, and to fill a fuel gas into the gas fuel vehicle 1 smoothly. Therefore, even users who are not familiar with the filling operations can still easily carry out the filling operations of the fuel gas into the gas fuel vehicle 1 .
  • a fuel cell vehicle which mounts a fuel cell generating electric power using a fuel gas consisting of a hydrogen gas was described as an example, however, the present invention is not limited to fuel cell vehicles as long as the vehicle is a gas fuel vehicle that runs on gas as a fuel.
