To provide an intake device for an engine, which can suppress excessive cooling of EGR gas.SOLUTION: An intake device 500 includes an intake passage 20, an EGR passage 41, and an EGR cooler 42. In the intake device, the intake passage 20 is provided with a lateral intake passage portion 325 that is provided on one side of an engine body 1 in a vehicle width direction. The EGR passage 41 is provided with a downstream-side EGR passage portion 341 that is provided on the one side of the engine body 1 in the vehicle width direction by dividing the EGR passage 41 on a downstream side of the EGR cooler 42. The downstream-side EGR passage portion 341 is disposed such that at least a part thereof is located behind the lateral intake passage portion 325 and overlaps with the lateral intake passage portion 325 when viewed from the front of a vehicle.SELECTED DRAWING: Figure 8 【課題】ＥＧＲガスの過冷却を抑制できるエンジンの吸気装置を提供する。【解決手段】吸気通路２０と、ＥＧＲ通路４１と、ＥＧＲクーラー４２とを備える吸気装置５００において、吸気通路２０に、エンジン本体１の車幅方向の一方側に設けられた側方吸気通路部３２５を設け、ＥＧＲ通路４１に、ＥＧＲクーラー４２よりも下流側のＥＧＲ通路４１を区画してエンジン本体１の車幅方向の一方側に設けられる下流側ＥＧＲ通路部３４１を設け、下流側ＥＧＲ通路部３４１を、その少なくとも一部が側方吸気通路部３２５よりも後方に位置し、且つ、車両の前方から見たときに側方吸気通路部３２５と重複するように、配設する。【選択図】図８
