Zusammenfassung:	To realize the miniaturization and the reduction of weight of a vehicle-use intake system by suppressing the increase of the number of parts. In a vehicle which includes an air cleaner for purifying air supplied to an engine, to an upper wall which constitutes at least one wall for forming an air cleaner, a stepped surface formed in a stepwise manner in which an outer step is arranged on a periphery of an inner step is provided. By providing the stepped surface to the upper wall, the upper wall is formed into a stereoscopic shape. Accordingly, the rigidity of the upper wall is enhanced and hence, the resonance of the upper wall can be suppressed thus reducing intake noises. It is sufficient to merely provide the stepped surface to the upper wall of the air cleaner and hence, it is unnecessary to particularly add a part for reducing intake noises.
