PROBLEM TO BE SOLVED: To provide a construction machine in which engine noise itself entering an air intake passage is reduced and a noise reduction effect in the air intake passage is enhanced to enhance a sound reducing effect.SOLUTION: An engine, a heat exchanger 10, and a cooling fan are arranged in an engine room, and external air is introduced into the engine room by the rotation of the cooling fan to pass through the heat exchanger 10. An air intake duct 12 is disposed at a position higher than the heat exchanger 10 in a back-and-forth direction in the upper part of a device space 6 disposed at the front right side of the engine room, and the external air sucked from the intake port 12a of a front end is passed over the heat exchanger 10 to enter the air intake surface 10a of the heat exchanger 10. |
