PURPOSE: A cooling fan of a radiator is provided to obtain a maximum result in a decided layout by overlapping the cooling fans. CONSTITUTION: A device for the cooling fans comprises a shroud(110) and a cooling fan device(120). The shroud is installed in a radiator(101) circulating coolant through a cylinder block and a cylinder head. A first installation device(111) is formed near the radiator and a second installation device(112) is formed in the shroud while overlapped with the first installation device and protruded more than the first installation device. The cooling fan installs a first and a second cooling fan(122,124) while overlapping the first and the second cooling fan in a blowing direction. Thus, maximum airflow is obtained in a decided layout to sufficiently cool the coolant of the radiator.
