The purpose of the present invention is to provide an engine device with which the workability of assembling an engine (1) can be improved and the workability of maintaining the engine (1) can be improved, while favorable ventilation performance of an outer peripheral section of the engine (1) can be maintained. This engine device is provided with a first case (28) for removing particulate matter in exhaust gas of the engine (1), and a second case (29) for removing nitrogen oxide matter in the exhaust gas of the engine (1). The second case (29) is connected to the first case (28) via a urea mixing tube (39). Provided are a plurality of support leg bodies (82, 84, 86) having one end side coupled to the engine (1), and a support base (87) coupled to the plurality of support leg bodies (82, 84, 86). The first case (28) and the second case (29) are disposed on the support base (87).
