Summary:An adjustable bottom retainer used in coordination with a non-pull cord window blind includes a base, and first and second worm rods. The base is disposed in a bottom beam of the window blind and has a set of ladder cord inserting holes. The first worm rod is inserted in the base and has a rotation driving hole exposed on the bottom surface of the bottom beam, enabling a hand tool to be engaged with the rotation driving hole to drive the first worm rod. The second worm rod is inserted in the base, engaged with the first worm rod, and fastened to bottom ends of first and second longitudinal strings of a ladder cord. Therefore, rotating the first worm rod makes the second worm rod engaged therewith wind the first and second longitudinal strings, thereby adjusting the total length of the ladder cord.
