Zusammenfassung:	To provide a wind power generation device in which cooling performance of a control device installed within a hub is improved. Disclosed is a wind power generation device including a rotor that includes a hub 20 housing a control device and blades 1 supported by the hub 20; a nacelle 6 that rotatably supports the rotor; and a rotation main shaft 3 that is disposed across an inside of the hub and an inside of the nacelle 6. A flow path for communicating the inside of the hub 20 and the inside of the nacelle is formed, the flow path is disposed on a radially outer side of the rotation main shaft 3 and is fixed to the nacelle 6. A first flow-out hole is provided in the flow path on the inside of the hub 20.
