Abstract
A housing of an air cleaner has an air inlet port and an air outlet port, and incorporates an air filter. In the housing, a fuel adsorption filter is arranged downstream of the air filter in such manner as to intersect an air passage. An open portion and a sheet-like adsorption portion are vertically defined in an outer frame of the fuel adsorption filter. The adsorption portion has a fuel adsorbing function. A weir is provided in a boundary between the open portion and the adsorption portion. The weir limits air flow from the upstream side of the adsorption portion to the upstream side of the open portion. A flow straightening plate having a flow straightening function is provided in the open portion.
