Abstract: To provide a wind power generation device in which wind received at the convex-side surface of concave panel parts is guided into a front edge airflow reservoir, thereby making it possible to improve the reliability of starting at startup and to increase the amount of power generated. Wind-receiving paddles 5 have: concave panel parts 51, which have a vertically elongated shape and which curve or bend in a concave shape on an inner-side surface 516 or an outer-side surface 515 in plan view; and front edge airflow reservoirs 52 formed in a projecting manner on a concave-side-surface 511 side along the longitudinal direction of front edge parts 513 of the concave panel parts 51 with respect to the direction of rotation, the tip section of the front edge airflow reservoirs 52 curving or bending towards the rear-edge side.

Abstract: [Problem] To provide a wind power generation device that, by using a structure that easily receives drag, improves the certainty of starting up on activation and is capable of increasing the amount of electric power generated from natural energy by the entire device.
