ABSTRACT:
A collapsible sunshade includes a frame and a top cover which is mounted on the frame. The frame includes a shaft which has an outer tube and an inner tube that is telescopically inserted into the outer tube. A runner assembly is sleeved on the outer tube. A main rib assembly is pivoted to a top end of the inner tube for mounting the top cover. A collapsible stretcher assembly is pivoted to the main rib assembly and is connected to the runner assembly. The runner assembly can cooperate with a bottom end of the inner tube so as to move the inner tube upward and outward from the outer tube simultaneously with the stretching of the main rib assembly. Preferably, the main rib assembly is collapsible, and has pivot connectors that impede the collapsing of the main rib assembly.
