To prevent condensate water generated in an intake passage from being excessively directed to an engine main body.SOLUTION: An intake device of an engine includes an intercooler 23, and an intake passage 20 including a downstream-side intake passage 24 positioned at a downstream side with respect to a chamber 51 of the intercooler 23. The chamber 51 includes a downstream-side wall 514 having an intake air delivery opening 54 for delivering the intake air passing through an intercooler core 52 to the downstream-side intake passage 24, and a bottom cover member 53 including a storage recessed portion 531 for storing condensate water generated in the downstream-side intake passage. The intake air sending opening 54 is disposed on a lower region of the chamber 51. The storage recessed portion 531 is disposed at a lower part of the intake air delivery opening 54 with a positional relationship including an overlap region OL partially overlapped to the intercooler core 52 in a vertical direction.SELECTED DRAWING: Figure 6 【課題】吸気通路内で生じる凝縮水を過度にエンジン本体へ向かわせないようにする。【解決手段】エンジンの吸気装置は、インタークーラー２３と、インタークーラー２３のチャンバ５１よりも下流に位置する下流側吸気通路２４を含む吸気通路２０とを備える。チャンバ５１は、インタークーラーコア５２を通過した吸気を、下流側吸気通路２４へ送出する吸気送出開口５４を有する下流側壁５１４と、下流側吸気通路において発生する凝縮水を貯留する貯留凹部５３１を備えた底蓋部材５３とを含む。吸気送出開口５４は、チャンバ５１の下方領域に配置されている。貯留凹部５３１は、吸気送出開口５４の下方であって、インタークーラーコア５２と上下方向に一部重複する重複領域ＯＬを含む位置関係で配置されている。【選択図】図６
