Abstract
In an engine generator having a work generator arranged at the upper side of an engine of a vertical crank shaft type, the output shaft of the engine projects upwards from the engine crank case so as to be connected to the rotor of the work generator. And the stator is arranged so as to encircle the rotor and to be encircled by an air induction casing. A cooling fan of a centrifugal blower type is located at the upper end of the rotor shaft with the blades thereof directed to the side of the generator so as to supply a cooling air flowing upwards to both the interior and the exterior of the stator during operation.
