PROBLEM TO BE SOLVED: To provide a non-contact magnetic gear enabling conversion of a gear ratio with a simple structure.SOLUTION: A non-contact magnetic gear has: a first gear that is formed into a substantially disc shape, and along the outer peripheral surface of which plural magnets having a surface facing a tangential direction are provided; and a second gear that is formed into a substantially disc shape or substantially cylindrical shape, and along the outer peripheral surface of which plural magnets having a shape along an outer periphery are provided. The rotational shafts of the first and second gears are positioned in parallel, and the first and second gears are arranged so that the respective outer peripheral surfaces are separated from each other with a predetermined interval. Polarities of surfaces opposite to the magnet of the first gear and the magnet of the second gear are identical to each other.SELECTED DRAWING: Figure 1 |
