装置。 A suction passage that guides blow-by gas from the crank chamber to the downstream side of the throttle valve in the intake manifold via the PCV valve, and fresh air filtered by the air cleaner that is diverted from an air duct upstream of the throttle valve to guide the fresh air to the crank chamber. In a blow-by gas reduction device for an internal combustion engine that includes a passage, an oil separator is provided at a branch part of the fresh air passage from the air duct, the separator forms a cooling chamber around the outer periphery of the air duct, and the oil separator is connected to the cooling chamber through a communication hole. A blow-by gas reduction device for an internal combustion engine, which communicates with an air duct, and is characterized in that a fresh air passage is connected to the upper part of the cooling chamber, and an oil return passage leading to an oil pan is connected to the lower part.
