To allow an exhaust emission control system 2 to be highly rigidly arranged as compact as possible in an engine 1 as a component of the engine 1.

An engine device includes an exhaust emission control system 2 which purifies exhaust gas from an engine 1. The exhaust emission control system 2 is mounted on the engine 1 so that a longitudinal direction of the exhaust emission control system 2 is orthogonal to an output shaft 3 of the engine 1. A cooling fan 9 is provided on one side face of the engine 1 intersecting with the output shaft 3. At a position, nearer to the cooling fan 9, of a top face side of the engine 1, the exhaust emission control system 2 is supported by a cylinder head 5.
