Abstract: A construction machine includes a cooling fan (10) and a shroud (11). The cooling fan (10) sends air drawn in via a radiator (30) to an engine. The shroud (11) is disposed on an outer peripheral side of the cooling fan and forms a passage for air to be drawn in via the radiator. The construction machine includes a tank (12) and a cover (14B). The tank (12) is disposed superior to an upper end portion of the radiator and stores cooling water to be supplied to the radiator and the engine. The cover (14B) is disposed openably in an opening (14A) formed in a top surface plate (11B) of the shroud. The tank (12) is disposed at a position adjacent to the shroud (11) on a side closer to the engine side than the cover (14B) is.
