Constant force spring/flat spring/coil spring /rolling spring 

A constant-force spring is a spring for which the force it exerts over its range of motion is a constant. Generally constant-force springs are constructed as a rolled ribbon of spring steel such that the spring is relaxed when it is fully rolled up. As it is unrolled, the restoring force comes primarily from the portion of the ribbon near the roll.
