Winding device for a roller shade with a self-locking function to prevent the roller shade from incurring detachment during reverse rotation
A winding device for a roller shade includes a side bracket (1), a self-locking unit (2) and a return wheel module (3). The self-locking unit is mounted in the side bracket and includes at least one support member (21) and 5 at least one stop member (22). The return wheel module is mounted in the side bracket and includes a return wheel (31), a winder wheel (32) and a volute spiral blade spring (33) stretched between the return wheel and the winder wheel. The volute spiral blade spring has a distal end (331) connected to the winder wheel and is provided with a locking portion (332) that is located at the 10 distal end and is movable to lock the at least one stop member.
