To provide a cooling device for a construction machine which enables maintenance work of a radiator to be easily performed and inhibits damage of an air intake pipe.SOLUTION: An air intake duct 40 is disposed at an upstream side of a radiator 35 in an air circulation direction. A vehicle front part of the air intake duct 40 is supported so as to rotate around a center shaft 47 extending in a vertical direction. An air intake pipe 52 connecting the interior of the air intake duct 40 with an engine 31 is connected to the air intake duct 40. A deformation allowable part 53 is provided at the air intake pipe 52. The deformation allowable part 53 deforms in conjunction with rotation operation of the air intake duct 40.SELECTED DRAWING: Figure 7

    【課題】ラジエータのメンテナンス作業を行い易くするとともに、吸気パイプの破損を抑える。【解決手段】ラジエータ35よりも空気流通方向の上流側には、吸気ダクト40が配設されている。吸気ダクト40の車両前部は、上下方向に延びる中心軸47を中心に回動可能に支持されている。吸気ダクト40には、吸気ダクト40の内部とエンジン31とを繋ぐ吸気パイプ52が接続されている。吸気パイプ52には、変形許容部53が設けられ、変形許容部53は、吸気ダクト40の回動動作に伴って変形する。【選択図】図7
