PROBLEM TO BE SOLVED: To provide a wind power generation device enabling to manage the temperature inside a rotor head.

SOLUTION: The wind power generation device 1 comprises a drive-generation mechanism connected to the rotor head 4 mounted with a windmill blade 5 and stored and installed in a nacelle 3, and control equipment and the like stored and installed in a hub 7 of the rotor head 4. Herein, an air circulation guide 20 is provided for circulating air between the inside of the rotor head 4 and the inside of the nacelle 3 via a communication passage 9 formed between the rotor head 4 and the nacelle 3.
