An air filling device includes a first air chuck and a second air chuck. The first air chuck is fitted to a tire valve of a front wheel, and the second air chuck is fitted to a tire valve of a rear wheel. The air pressure of the front tire is set to, for example, 800 [kPa] with a first pressure regulator. When the carried load is maximum, the air pressure of the rear tire is set to, for example, 1000 [kPa] with a second pressure regulator. The pressure of the front wheel is adjusted using the first air chuck, and the pressure of the rear wheel is adjusted using the second air chuck. Since the air pressure of the front tire and the rear tire can be adjusted simultaneously, the period of time required for adjusting the air pressure is shortened.
