To provide a power generating device capable of generating power against a wide flow velocity by a simple structure by utilizing the flow of fluids such as water flow and wind.
This power generating device uses, as an energy source, a galloping vibration produced by forming a surface 10a perpendicular to the direction of a fluid flow in the cross section of a vibration generating body 10 without using, as an energy source, a forced vibration by the Karman's vortex of the fluid flow. Since the galloping vibration is produced in a wide flow velocity, an additional device for providing a plurality of natural frequencies or changing the natural frequency thereof which is required in a power generating device in which the forced vibration by the Karman's vortex is used as the energy source is not required. Thus, the power generation device can efficiently generate power in the wide flow velocity by using a simple mechanism.
