The present invention relates to a self-developing device using a Karman vortex, in the following implementing the self-generation power generation equipment as possible by using a Karman vortex generated in the river or ocean; Guide which is fixed upright in the river or ocean; Generators that are installed in a part length of said retention arm; Body surrounding the generator, for pivoting horizontally extending from said body and having first and second pair of support placed a distance from each other in the vertical axis; It provides a self-powered device using a Karman vortex comprising a; a rotator fixed to the rotating shaft to be rotatable at the ends of the band between the first and second rotating support shaft.
According to the invention, it is possible to obtain a very simple structure, yet small self-powered device, the installation is possible is possible, and effective alternative energy by implementing the initial installation and maintenance management is easy to effect development down.
