PROBLEM TO BE SOLVED: To provide a cooling structure of an engine incorporated type generator capable of efficiently cooling a stator coil with the simple constitution. SOLUTION: In this cooling structure of the engine incorporated type generator, a stator coil 44 fixed to a crankcase 28 and a cylindrical flywheel 42 installed on a crankshaft 33 so as to surround the outer periphery of the stator coil 44 are coaxially arranged in a magnet case part 47 extended to a crankshaft end side part of the crankcase 28, and a rotor magnet 43 is arranged on an inner peripheral surface of the flywheel 42 opposed to an outer peripheral surface of the stator coil 44. Cooling air flowing ports 49 and 50 for making cooling air flow in and out on the inside and outside of the magnet case part 47 are respectively formed along the crankshaft 33 in both side positions of the magnet case part 47 for sandwiching the stator coil 44.
