ABSTRACT:
A wind power generation device capable of improving power generation efficiency is provided. The wind power generation device according to the present invention comprises: a substantially cylindrical duct1having a side wall with a substantially wing section; an impeller2rotatable around an axis of the duct1;and a nacelle5that constitutes a streamlined pencil body3together with the impeller2and houses a generator4that uses torque of the impeller2. The duct1has the side wall with the wing section so as to be able to produce a reduced pressure area at a rear of the duct and prevent generation of swirl at the rear of the duct1. The pencil body3is provided so that a tip thereof is placed in the duct1and a rear end thereof protrudes from a rear end of the duct1so as to be close to a tip of the reduced pressure area produced at the rear of the duct1. Blades21of the impeller2are provided in a maximum wind speed area13in the duct1.
