PROBLEM TO BE SOLVED: To provide a portable or transportable spring-driven generator capable of generating power for a long time by reasonably combining components thereof with each other. SOLUTION: In the spring-driven generator, the spring force of a spring-driven assembly can be successively accumulated from a power spring on a first stage to a power spring on a final stage, a power spring winding means to be cooperatively rotated with a drive shaft for winding up the power spring provided on a frame is disposed on a center shaft, and a transmission gear mechanism for acceleration to be rotated together with the center shaft is provided on the frame. A rotational force control means to control the rotational speed of the rotary shaft to a predetermined value is provided on the frame, and the return force of each power spring of the spring-driven assembly is braked by the rotational force control means.
