Abstract
An unequal-torque coil spring and a spring motor thereof which is adapted for a curtain set that can automatically fold back a curtain; the same provides a feedback torque that responds to different stages of a curtain-folding working process and generates various corresponding torque in response, as each of the different stages requires a different force. Consequently, the curtain can be folded back at a steady speed, and positionally fixed at any height when the curtain is lowered.
