An air cleaner unit of the present invention includes a removable cleaner case having defined therein an outflow port, located below the filter element, for discharging an air, introduced into the cleaner case, towards the combustion engine and including a case body opening downwardly and a bottom plate closing the opening of the case body, and a filter element replaceably accommodated within the cleaner case for substantially purifying the air introduced into the cleaner case through an air intake port. A pedestal 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. This filter element within the cleaner case is removably mounted on the pedestal. The bottom plate has a mounting hole defined therein and encircling the outer peripheral surface of the pedestal.
