<P>PROBLEM TO BE SOLVED: To provide a bidirectional wind rotary machine and a wind turbine generator not requiring stopping and then restarting even if wind direction is changed over. <P>SOLUTION: Two rotors 10, 20 of which the rotation directions are opposite are provided. The rotors 10, 20 include hubs 11, 21 and a plurality of blades of which base part are fixed on the hubs 11, 21. Each blade 12, 22 have shapes expanding at an outer circumference side, and are disposed at position rotationally symmetric with respect to a rotary shaft. The rotors 10, 20 are constructed in mirror symmetry with respect to a surface perpendicular to the rotary shaft. A gap is formed between the blades 12, 22. <P>COPYRIGHT: (C)2009,JPO&INPIT |
