Abstract
Blow-by gas in a plurality of crank chambers (-) in a V-shaped internal combustion engine is led to a plurality of gas introducing chambers () via communicating holes (-). The blow-by gas then flows into an oil separator (), which extends in a front-aft direction of the internal combustion engine, from the gas introducing chambers (). The blow-by gas inlet () of the oil separator () is provided in the vicinity of the engine front or the engine rear. By providing a guide member () which guides the blow-by gas from the gas introducing chamber () which is closest to the blow-by gas inlet () to the blow-by gas inlet () in a direction heading away from the blow-by gas inlet () and then guides it to the blow-by gas inlet (), pumping loss in the internal combustion engine can be reduced.
