PROBLEM TO BE SOLVED: To make it possible for an adsorption sheet facing the peripheral wall of a protruding part of an outlet protruding into a cap to effectively adsorb evaporative fuel when the adsorption sheet is disposed to face the peripheral wall.SOLUTION: An internal combustion engine air cleaner 10 comprises: a case 20 having an inlet 22; a cap 30 having an outlet 32; a filter element 40 that is provided between the case 20 and the cap 30 and that captures dust; and an adsorption sheet 50 that is provided within the cap 30 and that adsorbs evaporative fuel. The outlet 32 has a protruding part 33 that protrudes into the cap 30, the adsorption sheet 50 is disposed to face a peripheral wall 34 of the protruding part 33, and a plurality of vent holes 35 through which the evaporative fuel passes is formed in the peripheral wall 34 of the protruding part 33.SELECTED DRAWING: Figure 1 |
