PROBLEM TO BE SOLVED: To improve cooling performance of an engine generator.SOLUTION: An engine generator 1 comprises: a water-cooled internal combustion engine body 13; a crankshaft 20 which has a first edge 20A protruded from one side of the internal combustion engine body; a casing 7 which houses the internal combustion engine body; a generator 3 which has a rotor 52 connected to the first edge; a first impeller 68 connected to the first edge at a point closer to a tip side than the generator; and a radiator 24 which is arranged at a position opposite to the first edge in the casing and cools cooling water circulated between the internal combustion engine body and the same. The casing has a first side section 7D arranged opposite to the radiator and a second side section 7B arranged orthogonal to the first side section. A first intake port 71 and a second exhaust port 78 are installed on the first side section and the second side section respectively.SELECTED DRAWING: Figure 6 【課題】 エンジン発電機の冷却性能を向上させる。【解決手段】 水冷式の内燃機関本体１３と、内燃機関本体の一側から突出した第１端２０Ａを有するクランクシャフト２０と、内燃機関本体を受容するケーシング７と、第１端に結合されたロータ５２を有する発電機３と、第１端における発電機よりも先端側に結合された第１インペラ６８と、ケーシング内において第１端と対向する位置に配置され、内燃機関本体との間で循環する冷却水を冷却するラジエータ２４とを有し、ケーシングは、ラジエータに対向する第１側部７Ｄと、第１側部と直交する第２側部７Ｂとを含み、第１側部に第１吸気口７１が形成され、第２側部に排気口７８が形成されていることを特徴とするエンジン発電機１を提供する。【選択図】 図６
