BREATHER APPARARTUS FOR INTERNAL COMBUSTION ENGINE FOR VEHICLE

In a breather apparatus for an internal combustion engine for a vehicle in which an air cleaner is disposed above a crankcase, and a breather tube for guiding blow-by gas exhausted from the crankcase is coupled with a breather chamber formed in the air cleaner, an upstream side flow path 47a with which a breather tube is coupled and a downstream side flow path 47b continuously extending in a substantially U shape from the upstream side flow path 47a are formed in the breather chamber 47. Separation of gas and liquid in the breather chamber in the air cleaner is thus improved.
