Abstract
There is provided an air cleaner in which air does not take along evaporated fuel adsorbed by an adsorbent of a canister. In an air cleaner ( ), within a casing ( ) comprised of a primary side case ( ) having an inlet ( ) at one side and a secondary side case ( ) having an outlet ( ) at the other side and in between the cases ( ) and ( ), there is provided a filter element ( ) in a vertical state with a filter medium ( ) folded in a zigzag that prevents dust flowing into an engine. The inlet ( ) and the outlet ( ) are both arranged above a center line of the casing ( ). Within the secondary side case ( ) of the casing ( ), at only the secondary side bottom of the filter element ( ), there is provided a canister ( ) comprising an adsorbent such as a granular activated carbon, a honeycomb activated carbon, an activated carbon fiber, or an activated carbon mixed paper, which adsorbs evaporated fuel, across approximately an entire width of the casing ( ) in a width direction, and in only an upper flow side half of an air flow direction.
