SOLUTION: The structure includes a cooling fan 5 provided on a crankshaft 4 protruded from a crank case 2, and a blower housing 7 covering the cooling fan 5. Cooling air generated by the cooling fan 5 which integrally rotates with the crankshaft 4 is guided to a cylinder block 3 by the blower housing 7. A cooling device 27 to which an oil filter 28 is attachable is installed to the crank case 2. The cooling device 27 has a cooling part for cooling lubricating oil x flowing into the oil filter 28 or discharged from the oil filter 28 with the cooling air, and the cooling part is disposed within the blower housing 7.
