置。 A cylinder head cover of a slant type internal combustion engine in which the cylinder bore axis when viewed from the direction of the crankshaft is inclined with respect to a horizontal plane, communicates with the upper part of the cylinder head cover through a blow-by gas inlet, and blow-by gas treatment. In a blow-by gas extractor comprising: a gas-liquid separation chamber provided with a blow-by gas outlet to a cylinder head; and an oil outflow hole provided at the bottom of the gas-liquid separation chamber, an opening of the oil outflow hole into a cylinder head cover; A check valve is provided on the valve seat surface to allow only flow from the gas-liquid separation chamber toward the cylinder head cover, and
A blow-by gas extraction device for an internal combustion engine, characterized in that the valve seat surface is inclined at an inclination angle approximately halfway between a plane perpendicular to the cylinder bore axis and a horizontal plane.
