PURPOSE: Sun screen structure of a folding portable chair is provided to shield strong sunlight in the daytime by movably installing an elastic pole in the lightweight aggregate of a backrest and by installing a foldable sun screen in the pole. CONSTITUTION: Aggregate structure(110) of a folding portable chair(100) with sun screen structure comprises; lightweight aggregates(112a,112b,114a,114b,116a,116b,118a,118 b) rotatively contacted each other on a rivet pin(122) in an X-shape; lightweight aggregates(120a,120b) for a backrest; a forward and a rearward supporting mold(130a,130b) rotatively connected to the lower ends of the horizontal forward lightweight aggregates(112a,112b), the lower ends of the rearward horizontal lightweight aggregates(116b,118b), the lower ends of the horizontal rearward lightweight aggregates(114a,114b) and the lower end of the forward horizontal lightweight aggregates(116a,118a) within a specific range; a forward connecting mold(140a) rotatively connecting the upper ends of the horizontal forward lightweight aggregates and the upper end of the forward horizontal lightweight aggregates within a specific range; a rearward connecting mold(140b) rotatively connecting the upper end of the horizontal rearward lightweight aggregates and the upper end of the rearward horizontal aggregates; and a vertical moving mold(150) slides on the lightweight aggregates for the backrest. The sun screen structure consists of; a pole(200) vertically inserted into the lightweight aggregates for the backrest; a bent pole keeping device(210) keeping the pole bent; and a sun screen(220) of which one end is fixed to a backrest sheet(160a) and the other end is removably installed in each end of the pole. Thus, the sun screen screens strong sunlight or rain in the daytime.
