CONSTRUCTION MACHINE WITH EXHAUST GAS TREATMENT DEVICE
A urea water tank (27) is formed as a box body that includes a rear inclined surface (28A) that inclines so as to be parallel with a left inclined surface (7C) of a counterweight (7), a front inclined surface (28B) that inclines with a space being left apart from the rear inclined surface (28A) and in substantially parallel with the rear inclined surface (28A) and a front surface (28C) that is formed on front ends of the rear inclined surface (28A) and the front inclined surface (28B) and is formed into a flat surface that is parallel with a left-right direction of an upper revolving body (4). The rear inclined surface (28A) of the urea water tank (27) is disposed along and facing the left inclined surface (7C) of the counterweight (7) and the front inclined surface (28B) is disposed with a gap being left apart from and facing the heat exchanger (9). A cooling air guide passage (33) through which cooling air flows is formed between the heat exchanger (9) and the front inclined surface (28B) of the urea water tank (27).
