Abstract
A foldable umbrella capable of auto-adjustment of the umbrella cloth comprises: a plurality of foldable ribs; an umbrella pole for connecting one ends of the ribs; an umbrella cloth expanded along a space spanned by the ribs; at least one connection portion located on an inner side of the umbrella cloth and two adjacent ribs. Each connection portion includes two L-shaped retainers and one connecting unit; and each L-shaped retainer is made of flexible and bendable material. When the umbrella is folded, by the clamping effect of the two L-shaped retainers of one connection portion, the umbrella cloth will present a smooth folded shape so that the umbrella cloth is folded along the umbrella pole easily. Thus the umbrella cloth can be folded easily, rapidly, and directly with a beautiful outlook and a small size. It is difficult to be damaged.
