Abstract: A driving mechanism includes a rotatable support and a stretchable element which is being wound on the support by rotating the latter in one direction, and when the rotatable support is released the stretched element compresses and forcedly rotates the rotatable support in an opposite direction, thus providing a driving force in the opposite direction.
