Abstract:
An apparatus for generating rotative force using spring having:an input shaft; a main gear to which rotative force is transmitted by the input shaft; a spring wound spirally on an outer circumference of a main gear shaft, an inner end of the spring being fixed on the outer circumference of the main gear shaft, an outer end of the spring being fixed on a predetermined position; accelerating gears installed to a lower part of the main gear to increase rotative force of the main gear; an intermitting gear for intermitting rotative force of the main gear to the accelerating gears by sliding up and down along the rotation direction of the main gear with being engaged with the main gear; an output shaft outputting rotative force increased by the accelerating gears; and controlling means controlling rotating speed of the output shaft constantly, wherein elastic rotative force is stored into the spring as the input shaft being rotated by external force and the output shaft is rotated by the elastic rotative force stored in the spring as the external force being removed from the input shaft, being characterized in that the intermitting gear is supported toward the accelerating gear by elastic force so that rotative force of the main gear is transmitted to the accelerating gears through the intermitting gear although the apparatus is inclined or upside down.
