Abstract:
Pressure variation inside a fuel tank is suppressed even if an operation for opening and closing a breather passage is not performed, and leakage of liquid fuel can be suppressed even if the tank is inclined in a prescribed direction. An engine generator 1 has: a first breather passage 31 having an opening 31K in a position above the liquid fuel in a tank bulge section 22B when the engine generator 1 is inclined to the right (equivalent to a first direction); and a second breather passage 32 having an opening 32K in a position above the liquid fuel in the tank bulge section 22B when the engine generator 1 is inclined to the left (second direction).
