The utility model relates to an ultra-rotary-speed bearing-less revolving joint with a leakage-preventing device, and is composed of a leakage-preventing device arranged on an engine platform. The leakage-preventing device directly securely locks a connecting member connecting with the leakage-preventing device on the engine platform by tripping an inner hexagonal driving portion. A first surface is extended slightly toward an outer surface from the inner hexagonal driving portion in an ultra-rotary-speed way and communicated with a second surface of a second joint in a separate way. A partitioning portion is formed by the connecting member and a first joint. By mean of this, the utility model has the multiple effects that the revolving joint concurrently has a concealed driving function, the installment space for the elements are greatly increased and the oil stain is prevented from entering the engine platform and the loss resulting in the friction between the connecting member and the second joint can be reduced with a design of separating the elements.
