DRIVING MECHANISM FOR ROLL BLIND CAPABLE OF SHADE ADJUSTMENT
A driving mechanism for a roll blind capable of shade adjustment is proposed. The driving mechanism includes: a cover housing (212) having a stopper (212c) protrudingly foamed; a driving shaft (213a) relatively and rotatably coupled to the cover housing (212); a torsional coil spring (220) wound and tightened around an outer circumferential surface of the driving shaft (213a); and a clutch wheel (223) integrally rotating with the driving shaft (213a), wherein, in a case when the torsional coil spring (220) is caught by the stopper (212c) while the driving shaft (213a) is rotating, rotation of the torsional coil spring (220) is blocked therethrough, whereas the driving shaft (213a) is continuously rotatable regardless of whether the rotation of the torsional coil spring (220) is blocked, and wherein the driving mechanism further includes a tilting gear (222) and a tilting wheel (224) rotated in conjunction with the tilting gear (222).
