A D.C. motor-generator and an electric double layer capacitor are fixedly connected directly to each other and a rotary shaft of the motor-generator is rotated in one direction by an external force to generate D.C. electric energy which is stored in the electric double layer capacitor. By supplying the electric energy from the electric double layer capacitor to the D.C. motor-generator, the stored electric energy can be discharged as mechanical rotation energy. By deriving the stored energy as electric energy, an emergency power source can be provided.
