PROBLEM TO BE SOLVED: To expand capacity of a urea water tank even in a limited space, and to improve water supply workability and maintenance workability of the urea water tank.SOLUTION: A cab backward overhang beam 14 positioned on the front side of a heat exchanger 26 and supporting the rear side of a cab 28, is formed in an inverse L shape constituted by a rise-up plate 14A rising up from a bottom plate 6, an upper horizontal plate part 14B bending from the upper end of the rise-up plate part 14A and extending to the rear side and a space part 14C formed of the rise-up plate part 14A and the upper horizontal plate part 14B. A urea water tank 34 is formed as an L-shaped vessel constituted by a vertical tank part 35 positioned on the rear side and extending in the vertical direction and a horizontal tank part 36 extending to the front side from a lower part of the vertical tank part 35. In addition to this, the horizontal tank part 36 of the urea water tank 34 is arranged in the space part 14C of the cab backward overhang beam 14. |
