PURPOSE:To achieve a compactness of a motorbicycle by unifying a casing of a supercharger rotor and a housing of an air cleaner together in a formation process. CONSTITUTION:A supercharger 30 having a screw-like pair of rotors 31 is defined between an air cleaner 20 and a carbureter 18. A housing 22 of the air cleaner 20 being casted using an alluminum alloy in a formation process, with the elongated housing body 23 and a side board 24b on the right, a casing 33 of a rotor 31 are unified in a formation process. Thereby the piping that links the air cleaner and the supercharger is no more necessary, thus a compact structure can be obtained. |
