気装置。It has a sub-intake passage that branches from the main intake passage downstream of the throttle valve of the carburetor and leads to a sub-intake port that opens toward the combustion chamber near the intake port, and has a main intake passage between the branch point and the intake port. In a spark-ignition internal combustion engine that has a second throttle valve in the intake passage that responds to engine load, even when the second throttle valve is throttled to the maximum, there is a gap between the second throttle valve and the inner wall of the main intake passage over the entire circumference. An intake device for a spark-ignition internal combustion engine, characterized in that the intake device comprises:
