Beschreibung
Zusammenfassung:	A first fuel storage portion (46) is disposed on the upstream side of a fuel supply device (6) of an engine (E) so as to be contiguous with an air-intake passage (24) of the fuel supply device (6). A blow-back suppression plate (66) for suppressing blow-back from the air-intake passage (24) is disposed between a filter element (40) and the first fuel storage portion (46) of an air cleaner (8). A suction-back passage (54) is formed such that fuel accumulated in a fuel accumulation portion (52) in the air cleaner (8) is suctioned back through the suction-back passage (54) into the air-intake passage (24). The suction-back passage (54) allows communication between the fuel accumulation portion (52) in the air cleaner (8) and a suction-back port (56) formed at the downstream-side end of the first fuel storage portion (46).
