PROBLEM TO BE SOLVED: To reduce a portion required to be sealed in an air cleaner with which a resonance muffler is integrated.SOLUTION: A resonance muffler is integrated with an air cleaner 1. The air cleaner 1 includes cases 11, 12, a filter element 13 and a partition wall member 14. The partition wall member 14 is provided on the inner side of the case to partition part of an expansion space C on the inner side of the case, and a volume chamber V is defined by the case and the partition wall member 14. In a portion at least including two regions arranged opposing to each other of a peripheral edge of the partition wall member 14, predetermined gaps g are provided between the peripheral edge of the partition wall member 14 and the case 11. The gaps g serve as communication holes for communicating the expansion space C and the volume chamber V of the air cleaner with each other, and the volume chamber V and the communication hole constitute a resonance muffler.SELECTED DRAWING: Figure 1 |
