Abstract: An end weight device for horizontal fabric blind includes the front and rear meshed screens fixed to a winding rod rotatably installed inside a head rail. The front and rear meshed screens are secured to each edge of a plurality of shield slats, so that sunlight can be shielded. While the plurality of shield slats is maintained in a level state, the blind allows entering the sunlight and venting air. The meshed screens are tensioned responding to pull the operating string. Since a plurality of shield slats are maintained in a level state with the front and back meshed screens due to the end weight device, the front and rear meshed screens are not separated from each other.
