ABSTRACT:
A reeling unit for a blind has a base (30) and a roller (40). The base (30) has a bottom plate (31), two side brackets (34, 35), and a string hole (33) defined in the bottom plate (31). The roller (40) has two ends (44, 43) pivotally mounted on the two side brackets (34, 35) of the base (30) and has a tapered body (41) wound with a string (50). By sliding on the tapered body (41), the string (50) is automatically and orderly arranged on the roller (40) to avoid tangles and overlaps of the string (50). Additionally, because each reeling unit (20) individually collects a single string (50), even multiple reeling units (20) mounted on a window accessory will not interfere with each other so that tangling problem of the string (50) between elements of the window accessory is avoided.
