The present invention relates to a method for manufacturing a ball chain for driving a screen rod of a roll blinder. At least one ball (16) among several balls (14, 16) injection molded by using synthetic resin on a rope (12) is divided into male and female connectors (22, 24), so safety accidents caused by a stranglehold of children can be prevented. The male and female connectors (22, 24) are injection molded through support members (18, 20) injection molded beforehand in the end of each rope (14). Even though the width of a connection part for being connected to the rope (12) is narrow, firm connection to the rope (12) is secured. |
