PROBLEM TO BE SOLVED: To enable the output of an energy conversion device having a plurality of permanent magnets disposed in a ring shape to be enhanced.SOLUTION: A cover 3 is attached to a ring-shaped magnet holder 2 in which permanent magnets 1 are housed. An extension portion of the cover 3 is supported by a wheel 6. The wheel 6 is in contact with the extension portion of the cover 3 and a bottom of a case 5. For this reason, if the weight of the magnet holder 2 is increased by increasing the number of permanent magnets 1 housed in the magnet holder 2, the magnet holder 2 can be lightly rotated. Consequently, an energy conversion device 100 can extract more energy from given energy, thereby enhancing the output. |
