PURPOSE: A cooling fan for a radiator is provided to reduce the cost invested and time for developing a cooling fan of a new vehicle by making a cooling fan adjustable to the model of the new vehicle. CONSTITUTION: A cooling fan(1) comprises a hub(2) and a plurality of blades(3). A plurality of fitting portions(4) are formed on the outer face of the hub. A disk(5) or radial ribs are formed at a rear portion of the hub. A motor shaft is fitted in the shaft mounting holes(6) of the disk. Slide units(7) interferingly fitted in the fitting portions are prepared at the lower portions of the blades. The slide units are assembled by horizontal sliding. When a new vehicle is designed or a blade is changed, only the blade is re-designed. Therefore, the cost and time for developing a cooling fan for a new vehicle are reduced.
