ABSTRACT OF THE DISCLOSURE A component framework structure for a fold- able umbrella avoids channeled frame parts so as to make its various auxiliary stretchers fold into an abreast position instead of overlapping. Various stret- chers on both the left and right sides have flat and thin structures while their head joints are in conjunc- tion with an upper notch member of the umbrella where- by the joints are positioned under the bottom of the notch. The outside part of the joints thus does not protrude beyond the diameter of the upper notch, so that the tail part of the foldable umbrella, after it is folded up, becomes very slim with new practical effectiveness achieved in its carrying, packing and outer appearance.
