関の吸気装置。 A main air passage that is opened and closed by the throttle valve and an auxiliary air passage that bypasses the throttle valve are formed in the throttle chamber, and a duct made of an elastic material is connected to the throttle chamber. A main duct part that guides intake air to the main air passage and an auxiliary duct part that guides intake air to the auxiliary air passage are each integrally formed in the duct, and blow-by gas is communicated with the crank chamber in the middle of the main duct part. An intake device for an internal combustion engine, characterized in that an intake port is opened, and the auxiliary duct portion is located upstream of the blow-by gas intake port and opened.
