The purpose of this invention is to use vehicle-movement-generated wind to improve the cooling performance of an EGR cooler in an engine intake device that is provided with an EGR device whereby exhaust gas emitted by the engine is recirculated back to an intake passage as recirculated exhaust gas and is also provided with an air cleaner that cleans intake air (fresh air) and supplies same to the intake passage. To that end, an air-cleaner case (26) for the air cleaner (24) is laid out above the EGR cooler (34), which cools the recirculated exhaust gas from the EGR device (30). The air-cleaner case (26) is laid out such that the lengthwise direction thereof is parallel to the lengthwise direction of the EGR cooler (34).
