PROBLEM TO BE SOLVED: To suppress temperature rise of fuel stored in a fuel tank arranged in an engine compartment. SOLUTION: The outside air sucked by an air cleaner 150 is supplied to an engine 10 in operation of the engine. At that time, a sub tank 100 arranged in a second chamber 162 of the air cleaner 150 is cooled by the outside air. Therefore, temperature rise of the sub tank 100 by the heat generated by the engine is suppressed, and as a result, the temperature rise of the stored gas fuel can be suppressed.
