Abstract:

To provide a windmill being lighter in weight than Savonius windmill, easy to expand, and suited for practical use as it smoothly rotates even at moderate winds and ensures high efficiency; to provide a wind power generator using such a windmill.

The windmill has not less than one or two rotary vanes which, upon receiving wind force, rotate on a circumference about a vertical rotating shaft coupled to the rotary vanes. The rotary vane is provided with a non-oscillating end running along one vertical direction, a movable end horizontally rotatable using the non-oscillating end as a fulcrum, and a free end capable of being oscillated by wind and running along the other vertical direction. The non-oscillating end is coupled to a coupling member to couple each rotary vane to the rotating shaft.
