A Window coverings string coiler includes a hollow casing, a gear set, a string winding wheel set, two resilient plates, a synchronous control member, and a control set. The string winding wheel set and the gear set include first and second string winding wheels and first and second gears coupled with each other and also pivotally coupled to the interior of the casing. The synchronous control member is coupled to the first and second gears for controlling synchronous rotations. The control set controls the scrolling or opening operation of the blind vane, such that the first and second gears coupled to the string winding wheel set and the design of a synchronous control member for controlling the synchronous rotation of the first and second gears are used to achieve a consistent rotary speed of the first and second string winding wheels for coiling or releasing the pulling string.
