PROBLEM TO BE SOLVED: To provide a wind power generation system having an improved appearance in which a plurality of windmill units can be coaxially connected to one another and generators are also arranged coaxially. SOLUTION: The wind power generation system includes: a fixed shaft 10; the windmill units 2 each having blade members 4, 5 rotatable around the fixed shaft 10; first and second radial bearings 11, 14 for supporting both the axial ends of the blade members 4, 5; and the generators 8 which generate power in cooperation with rotation of the windmill units 2, the generators 8 being arranged coaxially with the fixed shaft 10. The first radial bearings 11 is each arranged on a rotatable part of the generator 8, the rotatable part being integrally connected to the windmill unit 2. First and second supporting plates 6, 7 are provided on both the axial ends of the blade members 4, 5. The generator 8 is secured to the first supporting plate 6. The first radial bearing 11 includes an outer ring attached to the rotatable part of the generator 8 and an inner ring fitted on the fixed shaft. A bearing housing 13 is provided on the second supporting plate 7. The second radial bearing 14 includes an outer ring attached to the bearing housing 13 and an inner ring fitted on the fixed shaft.
