To provide wind power generating equipment capable of being operated even under weak natural wind and capable of generating a large output even by a windmill with a small wind receiving area.

In this wind power generating equipment 10, an elliptic cylinder 12 is properly installed in front of the windmill 2 for performing a wind power generation so that the major axial end face A of the elliptic cylinder 12 can be overlapped with the extension line X of the rotating shaft of the windmill 2.
