ーバイガス還元装置。[Scope of Claim for Utility Model Registration] An oil separator is provided in the middle of the blow-by gas hose that communicates at least the inside of the rocker cover with the positive crankcase ventilation valve of the intake system, and the bottom of the oil separator is connected to the oil pan by an oil return pipe. In the blow-by gas reduction device, in which the oil separator is arranged at the rear of the engine body in the vehicle traveling direction, a communication hole with the oil return pipe inside the oil separator is connected to the oil separator so that the vehicle travels only during acceleration. A blow-by gas return device characterized by being equipped with a butterfly valve that closes due to inertia force in a backward direction.
