Claims

[Scope of utility model registration request]

A cooling fan 2 interlocked with the crankshaft 1 is arranged on the front of the engine E, the front thereof is covered with a fan case 3, the cooling fan 2 is housed in the fan case 3, and a recoil starter 4 is arranged in front of the fan case 3. A generator G is interlocked and connected to the back of the crankcase 5 of the engine E, a generator cooling fan 6 is positioned in front of the generator G, and a cooling air intake 10 is provided at the rear 8 of the generator body 7. In a forced air-cooled engine generator in which cooling air outlets 12 are provided at peripheral positions 11 of the generator cooling fan 6, a wind guide tube 15 is disposed above the generator G at the back 14 of the engine cylinder 13. It passes through the wind tunnel section 16 across the front and back of the wind guide tube 15, extends the front part 17 of the wind guide tube 15 downward to form an air intake port 18, and connects the upper end 19 of the air intake port 18 to the wind tunnel section 16. At the same time, the lower end 20 of the air intake port 18 is connected to the cooling air outlet 12, and the cooling air passing through the engine cylinder 13 is taken into the air guide tube 15 to increase the generator exhaust air. Air-cooled engine generator.
