Abstract
An air cleaner includes: an air cleaner box defining a clean chamber that is placed rearward of a dirty chamber, the clean chamber receiving air which has been introduced from front into the dirty chamber and then filtered through an air cleaner element; and funnels that are to be connected to an intake port of an internal combustion engine, the funnels protruding upward into a space within the air cleaner box from a bottom wall of the air cleaner box. The air cleaner further includes a breather chamber into which blow-by gas is introduced from the internal combustion engine, the breather chamber being placed rearward of the funnels and between the funnels and a rear wall of the air cleaner box. Accordingly, the air cleaner can further promote the air-liquid separation of blow-by gas without incurring an increase in weight of the internal combustion engine.
