<p>PROBLEM TO BE SOLVED: To generate a high output and high torque even when a windmill is small by a method wherein a windmill device is provided with an outer cylinder body gradually increased in a cross section area from upstream to downstream and the windmill is situated internally thereof in a spot closer to the upstream of an outer cylinder. SOLUTION: An outer body 1 gradually increased in a cross section area from upstream (the windward) to downstream (the leeward) is provided. A windmill 2 having a plurality of blades 2a is contained in a spot situated upper stream of the outer cylinder body 1. The windmill 2 is annexed rotatably around a horizontal axis L on one end side of a shaft member 3. Further, the outer cylinder body 1 is annexed rotatably around a vertical shaft B of a support member 4 at the upper end 4a of the support member 4, and the support member 4 is situated in a position closer to a front end than the central part in a longitudinal direction of the outer cylinder body 1. This constitution provides a high output and high torque though a small wind mill has a small windmill radius.</p> |
