PROBLEM TO BE SOLVED: To provide an intake device of an internal combustion engine with a supercharger capable of improving output performance of the internal combustion engine and preventing degradation of the output performance of the internal combustion engine by preventing air flowing in an intercooler outlet pipe from being heated.SOLUTION: According to an intake device 10, an intercooler outlet pipe 16 is provided with a large diameter portion 16A having a large internal diameter size of the intercooler outlet pipe 16 and a small diameter portion 16B having an inner diameter size smaller than the large diameter portion 16A, and the large diameter portion 16A is formed between a central portion C in the longitudinal direction of the intercooler outlet pipe 16 to a downstream end 16b connected to an intake air introduction pipe. The intake air introduction pipe is extended to a lower part of a vehicle 1 from a surge tank, and further extended to a lower part of an alternator 21 in a height direction of the vehicle 1, and the intercooler outlet pipe 16 is connected to the intake air introduction pipe from an air outlet pipe portion 19a through a lower part of a mount device 7 and the lower part of the alternator 21.

    【課題】インタクーラアウトレット配管を流れる空気が加熱されることを防止して、内燃機関の出力性能を高めることができるとともに、内燃機関の出力性能が低下することを防止できる過給機付き内燃機関の吸気装置を提供すること。【解決手段】吸気装置10によれば、インタクーラアウトレット配管16を、インタクーラアウトレット配管16の内径寸法が大きい大径部16Aと大径部16Aよりも内径寸法が小さい小径部16Bとを含んで構成し、大径部16Aを、インタクーラアウトレット配管16の長さ方向中央部Cから吸気導入管に接続される下流端16bまでの間に形成した。また、吸気導入管をサージタンクから車両1の下方に延長させるとともに、車両1の高さ方向においてオルタネータ21の下部に延長させ、インタクーラアウトレット配管16を、空気出口管部19aからマウント装置7の下方およびオルタネータ21の下方を通して吸気導入管に接続した。【選択図】図4
