A distributor structured for a 360-degree rotary ceiling fan comprises a main housing with an outer shell and a pedestal, a central shaft passing through the outer shell and the pedestal, and a power distribution ring unit around the central shaft in the main housing. The power distribution ring unit comprises several electrically conductive ring units and insulation ring units. The electrically conductive ring units are interlaced with the insulation ring units. One terminal of the electrically conductive ring unit is connected to an external power supply, while the other one is connected to a ceiling fan. The carbon brush being used, the environment even may be prevented from being polluted and the human body may be prevented from being harmed, the carbon brush does not easily bring poor electric conduction caused by dust, and the issues on difficult periodical replacement and maintenance of the carbon brush is solved.
