A cordless window curtain has a window curtain rod, a curtain body, lateral rails, a locating rope assembly and an elastic tension component. The reducing guide slots are set at one side of the lateral rails facing the curtain body and connected with the hollow slot. The width of the reducing guide slot must be smaller than that of the lateral rail and the width of the reducing guide slot is preferably between 2 mm and 5.9 mm. Two flanged guide shafts are protruded from both ends of the hollow bottom rod of the curtain body. These two flanged guide shafts are provided with a through-hole for threading of two lower locating sections of the locating rope assembly. The outer end of two flanged guide shafts is inserted into the reducing guide slot, such that the flanged guide shaft can slide vertically along the path of the reducing guide slot.
