To provide a bearing-type propeller eliminating a frictional resistance received from a fluid at a central portion of the propeller at which an mount of work is small, and allowing the fluid to efficiently flow along a pipe line while maintaining a kinetic energy direction of the fluid.

In the bearing-type propeller, a gear (3) or the like is provided to a bearing rotary portion (2). A bearing fixing portion (5) is provided to the bearing rotary portion (2). A bearing (8) is provided between the bearing rotary portion (2) and the bearing fixing portion (5). A propeller blade (1) is provided inside the bearing rotary portion (2). A fixed metal (6) is provided to the bearing fixing portion (5).
