Abstract
A retaining structure for a cordless continuous folding blind includes an upper beam, a continuous folding blind attached to the bottom of the upper beam, and a retaining plate fixed at opposing ends of a bottommost slat of the continuous folding blind via a fastening agent or seamed to the bottommost slat. The retaining plate has an extending section protruding outwards at each outer edge of the bottommost slat and a flexible counterweight stick securely fixed at an inner central section. The retaining plate is selectively bent and folded inwards to abut against a predetermined number of collected slats of the folding blind to locate the blind in a predetermined position.
