To provide a wind power generator configured to easily assemble and change omnidirectional wind at a low cost without using a speed changing action of a gear or a belt, with respect to natural energy having always changing unstable factors, and to generate stable power even in strong wind or a blast.

The wind power generator with connected units is formed by connecting one or more wind collection units with one or more power generation units to generate power from omnidirectional wind. In response to environmental changes after installation, the number of the wind collection units and the power generation units are changed to generate power suitable for an environment.
