Zusammenfassung:	PROBLEM TO BE SOLVED: To miniaturize and reduce the weight of an intake device for a vehicle by suppressing an increase in the number of parts of the intake device. SOLUTION: In the vehicle having an air cleaner 34 for purifying the air supplied into an engine, a stepwise step surface 66f on which an outer stage is disposed around an inner stage is provided to at least one upper wall 69 which constitutes the air cleaner 34. The upper wall 69 is three-dimensionally formed by the step surface 66f provided to the upper wall 69, and the rigidity of the upper wall 69 is increased, the resonance of the upper wall is suppressed, and the noise of intake air is reduced. Since the step surface 66f is merely provided to the upper wall 69 of the air cleaner 34, a special part to reduce the noise of intake air does not need to be added. COPYRIGHT: (C)2010,JPO&INPIT
