Abstract

A cord lock of the window blinds or shade (100) includes a box (10) having a chamber (11) therein, a driving device (14) on an outer side, a first opening (12) for a cord (80) exiting the box (10), a second opening (13) for the cord (80) entering the box (10), a fixed locking portion (17) on the outer side, and a flexible locking portion (18) opposite the fixed locking portion (17); and a movable driving wheel (30), which is received in the chamber (11) of the box (10), to be moved between a lock position, in which the movable driving wheel (30) is moved toward the driving device (14) to clip the cord (80) therebetween, and a release position, in which the movable driving wheel (30) is moved away from the driving device (14) to release the cord (80). The fixed locking portion (17) provides the box (10) fixing to the top rail (90) with a strong strength, and the flexible locking portion (18) provides an easy way to mount the box (10) on the top rail (90).
