A cordless roller shade mechanism is provided that holds at a desired position when no force is imparted thereon. When the roller shade is expanded, energy is stored in the roller shade. When the roller shade is to be retracted, a string is pulled to and the energy stored in the roller shade causes the roller shade to retract without the user imparting a rotational force on the roller shade.
