Work machine

A work machine, comprising a fuel tank for storing liquid fuel,

• wherein the fuel tank has a tank shape and includes:
• a fuel supply port;
• and a tank bulge section that bulges to a position higher than the fuel supply port, the tank bulge section being formed, at an intermediate position in a front-rear direction of the fuel tank, so as to have a cross section in which a front-rear length decreases to the upper side,
• wherein the fuel tank comprises a breather passage through which an inside and an outside of the tank bulge section communicate with each other, and
• wherein the breather passage comprises:
• a first breather passage having an opening at a position above the liquid fuel in the tank bulge section when the work machine is inclined in a first direction, the first direction being one of left and right directions, the position of the first breather passage opening being intermediate in the front-rear direction of the fuel tank, the first breather passage being routed so as to include a position above the liquid fuel when the work machine is inclined in a second direction, the second direction being the other of the left and right directions;
• and
• a second breather passage having an opening at a position above the liquid fuel in the tank bulge section when the work machine is inclined in the second direction, the position of the second breather passage opening being intermediate in the front-rear direction of the fuel tank, the second breather passage being routed so as to include a position above the liquid fuel when the work machine is inclined in the first direction.
