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