ABSTRACT:
A first air cleaner box (25) is provided on one side of a rear wheel (4) above a transmission case (9) of a unit-swinging power train unit (1), whereas a second air cleaner box (26) is provided on the other side of the rear wheel (9). Air compartments (40) of the air cleaner boxes (25, 26) are connected to a throttle valve (22) while the air compartments of the air cleaner boxes are made to communicate with each other. The second air cleaner box (26) can be provided by making use of a dead space defined on a side of the rear wheel (4). The capacity of the air compartment (40) can be increased by the first and second air cleaner boxes (25, 26) while preventing the enlargement of the vehicle body, whereby the output of an engine (3) can be increased by increasing the displacement of the engine (3).
