PROBLEM TO BE SOLVED: To provide an engine device capable of using a fuel tank also as a supporting member of an urea water tank, and simplifying a mounting structure of the urea water tank.SOLUTION: An engine device includes an urea mixing pipe 39 for injecting urea water into an exhaust gas of a diesel engine 1, a SCR case 29 for removing nitrogen oxide substance in the exhaust gas of the diesel engine 1, and an urea water supply device 73 for supplying the urea water in the urea water tank 71 into the urea mixing pipe 39. The urea water supply device 73 is connected to the urea water tank 71 through urea water pipings 80c, 80d. A recessed portion 111 is formed on a fuel tank 45 of the diesel engine 1, and the urea water tank 71 is supported by the recessed portion 111.SELECTED DRAWING: Figure 1
