The present invention relates to a hubless propeller. The present invention comprises: a propeller wing module where one propeller wing is formed in an integrated coupling unit of a divided hub structure; and a coupling ring formed on a center region of a shaft to be coupled and separated from a lower end protrusion of the propeller wing module. The propeller wing module is formed by the same number of the divided hub to be coupled and separated from the shaft, thus the propeller wing module where the existing propeller wing and the hub are integrally formed is easily coupled and separated from the shaft to easily be processed. Moreover, the present invention uses the propeller wing module in order to easily process an entire propeller, and easily replaces the propeller when a specific propeller wing is damaged.
