The present invention relates to free weight separation preventing devices separately coupled to both ends of a free weight in a roll blind which fixates one end of a blind sheet to a rotational winding rod and the other end to a rail member supporting the winding rod to hang down a central part of the blind sheet and forming the blind sheet to have two layers to make a front layer and a rear layer cross each other in a vertical direction when the winding rod rotates to roll up or down the blind sheet in a vertical direction, wherein the free weight has a cylindrical or a circular rod-shaped body in a predetermined length inserted between the front layer and the rear layer at the lower end of the blind sheet to make the front layer and the rear layer, crossing each other, tense in a vertical direction. To achieve the purpose, the free weight separation preventing devices for a blind according to an aspect of the present invention, for preventing the free weight (1) for the blind from being separated from the blind sheet (3), comprises: locking caps (11, 11′) mounted at ends of the rod-shaped free weight (1) in a predetermined length, inserted between the front layer and the rear layer at the lower end of the blind sheet (3) and including a coupling body (11b) coming into direct contact with the end of the free weight (1); and free rotational separation preventing members (12, 12′) in a predetermined weight and a U or L shape, which are coupled to the locking caps to be able to rotate. |
