1. A rolling machine including a drive device having an internal combustion engine for driving a vehicle body, the rolling machine comprising:
a first tank that is disposed in front of or behind the drive device, and stores fuel to be supplied to the internal combustion engine;
a second tank that is disposed below the drive device so as to be separated from the first tank by a predetermined distance, and stores fuel to be supplied to the internal combustion engine;
a first storage amount detection part that is disposed in the first tank, and detects an amount of the fuel stored in the first tank; and
a second storage amount detection part that is disposed in the second tank, and detects an amount of the fuel stored in the second tank, wherein
the first storage amount detection part detects the amount of the fuel stored in the first tank on the basis of a position of a liquid surface of the fuel at a vehicle body right-left direction center of the first tank, and
the second storage amount detection part detects the amount of the fuel stored in the second tank on the basis of a position of a liquid surface of the fuel at a vehicle body right-left direction center of the second tank,
the first storage amount detection part and the second storage amount detection part are float sensors in which arms vertically rotate with rotating shafts as axes, loci of floats include respective vehicle body front-rear direction centers of the first tank and the second tank,
the rotating shafts each extend in the vehicle body right-left direction,
the first storage amount detection part is disposed on a surface facing the drive device of the first tank, and
the second storage amount detection part is disposed on a surface facing the drive device of the second tank.
