An air cleaner unit ( 7 ) of the present invention includes a removable cleaner case ( 70 ) having defined therein an outflow port ( 101 ), located below the filter element, for discharging an air, introduced into the cleaner case ( 70 ), towards the combustion engine and including a case body ( 71 ) opening downwardly and a bottom plate ( 73 ) closing the opening of the case body ( 71 ), and a filter element ( 72 ) replaceably accommodated within the cleaner case ( 70 ) for substantially purifying the air introduced into the cleaner case through an air intake port ( 74 ). A pedestal ( 60 ) is carried by the combustion engine and has an outer peripheral surface, which is substantially in flush with an outer peripheral surface of the filter element within the cleaner case ( 70 ). This filter element ( 72 ) within the cleaner case ( 70 ) is removably mounted on the pedestal ( 70 ). The bottom plate ( 73 ) has a mounting hole ( 73 c) defined therein and encircling the outer peripheral surface of the pedestal ( 60 ).
