ABSTRACT:
A vehicular generator with at least one cooling fan, wherein a plurality of blades of the cooling fan are made of a shape memorizing alloy, whereby, especially in medium and high revolution speed operations and low electric loads in which cooling air is not required, the blades are flattened, thereby preventing the rotational efficiency of the generator from falling and reducing noise ascribable to the cooling fan.
