Abstract
The stroller with a linkage-foldable backrest having a stroller frame convertible between an unfolded state and a folded state is provided. The folding of the stroller frame of the provided stroller drives the backrest portion to fold, so as to prevent the edge of the end portion of the backrest portion from touching the ground. The folding operation of the backrest portion according to the present invention is simple and convenient.
