<P>PROBLEM TO BE SOLVED: To provide a power generating device that efficiently generates power by using water flow. <P>SOLUTION: The device includes a plurality of rotary bodies 10 that can rotate about respective axes, an annular body 20 bridged between the rotary bodies 10, a plurality of vanes 30 erected while keeping a space from each other on a front surface of the annular body 20, and a power generator 60 for generating power by rotations of the rotary bodies 10. The annular body 20 has an inclined part 21 which faces against a flow and inclining downwardly from upstream to downstream, and the annular body 20 is rotated by the vanes 30 of the inclined part 21 receiving the flow, and the rotary bodies 10 are rotated along with the rotation of the annular body 20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
