Embodiments of the present application relate to the technical field of propellers, and particularly to a folding propeller, a power component and an unmanned aerial vehicle. The folding propeller includes a hub, at least two blades and at least two connecting pieces, the hub being configured to mount the folding propeller to a driving device. The hub includes a first surface and a second surface disposed oppositely, the first surface facing the driving device, and the second surface facing away from the driving device. Each of the blades is mounted on the second surface by the corresponding connecting piece, and each of the blades is capable of rotating relative to the hub. In the above manner, according to the embodiments of the present application, during mold adjustment in injection molding, a rotary damping between the blade and the hub can be adjusted by only adjusting the friction force of one contact surface, which is convenient for mold adjustment, is beneficial to mass production and reduces the production cost.
