Abstract

Abstract A sunshade to be mounted on the back-rest member of a foldable chair or bed such as a three-fold chair primarily for an outdoor use. The sunshade comprises an awning sheet frame and a pair of support legs pivoted to one end thereof to support the frame shiftably in accordance with the reclination of the back-rest member and the direction of the striking sunlight. The support legs are formed at their lower parts with elongated ringlike portions in facing relation to each other for clamping the opposite shoulders of the back-rest member. The distance between a pair of the opposing support legs is smaller at their intermediate portions than the width of the back-rest member, whereby the support legs are resiliently urged inward about the pivoted portions when clamping the shoulders of the back-rest member from outside.
