。 A bottom plate that closes the bottom opening is attached to a bottom-open box formed on the inner surface of the cylinder head cover, and the inside of the box is configured as a gas-liquid separation chamber that communicates with the inside of the cylinder head cover. The chamber is communicated with an intake system upstream of the throttle valve via a first blow-by gas passage, and the inside of the cylinder head is communicated with an intake system downstream of the throttle valve via a second blow-by gas. In the blow-by gas extractor, an auxiliary box with an open bottom is formed adjacent to the box on the inner surface of the cylinder head, and an extension part that closes the open bottom of the auxiliary box is integrally formed on the bottom plate. The inside of the auxiliary box is formed into a chamber that communicates with the inside of the cylinder head cover, and the second blow-by gas passage is connected to the chamber through an auxiliary chamber having a smaller capacity than the chamber, and A communication portion of the gas-liquid separation chamber into the cylinder head cover and a communication portion of the chamber into the cylinder head cover are arranged at substantially diagonal positions in a plan view of the cylinder head cover. Blow-by gas extraction equipment for internal combustion engines.
