A structure of a multi-stage windmill includes a first housing(10'), a second housing(10"), a third housing(10), a cylindrical vertical shaft, and a rotary wheel(30). The first housing accommodates a first generator. The second housing accommodates a second generator. The third housing accommodates the first and second housing to operate the first and second generators.
