る吸気管構造。[Scope of Claim for Utility Model Registration] In an intake pipe structure for an internal combustion engine, the exhaust gas of the engine is guided into the intake passage downstream of the throttle valve, and the exhaust gas mixed with fresh air is combusted again. The outer edge of the valve body of the throttle valve, which is located in the fully closed position of the intake passage when looking from the intake downstream side to the intake upstream side, is located on the inner wall of the intake pipe near the throttle valve and between the inlet of the exhaust gas into the intake passage and the throttle valve. An intake pipe structure characterized in that a protruding wall part is formed so that a portion of the intake pipe is covered with a protruding wall part.
