A multi-rotor ceiling fan structure capable of stably revolving round a central axis thereof, which comprises a rotating disk fixedly joined with one or more rotating arms, an inner housing cover fixedly disposed on the rotating disk, a central axial rod fixedly joined at the ceiling, and a power transmission set. A fan is pivotally disposed at each end of the rotating arm. The lower end of the central axial rod passes through the centers of the rotating disk and the inner housing cover, and is tightly slipped onto a bearing structure placed between the centers of the rotating disk and the inner housing cover. A seat body having a conductor of the power transmission set is fixedly disposed on the inner housing cover. A conductive sleeve of the power transmission set is slipped onto the central axial rod. The conductor keeps electric contact with the conductive sleeve.
