The present invention relates to a reversely-folding umbrella having dual awning screens. The umbrella of the present invention includes: a central pole which is formed lengthwise at a certain direction; an elevation assembly which is installed on the central pole to be able to move vertically, and is hinged with one end of lower ribs for supporting a lower awning screen; a fixated assembly which is hinged with one end of upper ribs, and fixated to the central pole to enable a relative elevation of the elevation assembly; and auxiliary ribs which guide a bending action of the lower ribs while the elevation assembly moves closer to the fixated assembly, and maintain bent conditions of the lower ribs after the elevation of the elevation assembly is completed, by enabling one sides thereof to be hinged with the upper ribs and enabling the other sides thereof to be hooked on the lower ribs to be able to move. The upper ribs include a pair of foldable ribs whose facing ends are hinged in order to enable the upper awning screen to be accommodated in a space between the central pole and the lower ribs and to expose the inner side of the lower awning screen to the outside, when the elevation assembly descends toward a direction apart from the fixated assembly. |
