Abstract
There is provided a wind propulsion device for driving a transmission shaft connected through intermediate members with devices for force transmission. The wind propulsion device comprises a wind impeller having a plurality of wind wings which are concavely curved against the air stream. The wind wings are axially connected to a semisphere convexly curved against the air stream which is axially disposed with respect to said impeller. The semisphere guides the air stream impinging on the center of the impeller to the tips of the wings for efficient wind utilization.
