内燃機関のブローバイ通路。 In the blow-by passage of an internal combustion engine, which communicates between the crankcase and the inside of the cylinder head cover, and also connects the inside of this cylinder head cover with the upstream side of the intake system to recirculate blow-by gas to the upstream side of the intake system, the crankshaft is connected to the cylinder block. The cylinder block is held by a crank bearing cap, and the mating surface of either one of the lower surface of the cylinder block and the upper surface of the crank bearing cap is provided with a groove parallel to the mating surface that communicates with the lower end opening of the blow-by passage. A blow-by passage of an internal combustion engine characterized by:
