PURPOSE: A wind power generation apparatus for a train is provided to rotate fans with high force and produce a large amount of electricity by multiple air intake ducks having tapered inner diameter. CONSTITUTION: A wind power generation apparatus for a train comprises an air intake unit(10), a fan(20), a generator, a direct-current converter, and a storage battery. The air intake unit comprises a first air intake duct(11), multiple second air intake ducts(12), and a third air induction duct(13). The first air intake duct has inner diameter which is tapered. The multiple second air intake ducts are combined with the first air intake duct. The second air intake duct has multiple twist protrusions for vortex of air. The third air induction duct has an outer circumference path and twist protrusions. The air flows in one side of the outer surface of a fan through an outer circumference path.
