<p>A revolution assisting device for a rotating body comprises the rotating body provided on an outer peripheral surface thereof with permanent magnets, and a shaft connected to the rotating body by means of a crank mechanism and provided with permanent magnets, the shaft effecting vertical movements to assist revolution of the rotating body. The revolution assisting device for a rotating body further comprises a first magnet section and/or a second magnet section adapted to be slidingly moved in a diametrical direction of the rotating body by means of the crank mechanism which comprises the rotating body mounted to a rotating axis of a crank shaft and a connecting rod mounted to a crank arm of the crank shaft, and a first magnetic field arranged along the vicinity of a part or an entirety of a circumference about the center of rotation of the rotating body for generating an attracting force between it and the first magnet section, and/or a second magnetic field arranged along the vicinity of a part or an entirety of a circular path, which the second magnet section draws on a side surface of the rotating body, by its sliding movements, for generating an attracting force between it and the second magnet section. <IMAGE></p> |
