The sunshade has a stand (2) on the mast (6) of which is guided an extendable and retractable jib (10). The outer end (12) of the jib (10) supports a shade (14). In addition, a strut (18) is articulated between the jib (10) and the top of the mast (6). The inner end (8) of the jib is moved along the mast by means of a jib drive (20). The shade (14) is opened and closed by means of a shade drive (24). To improve its kink and torsional stability the mast has a closed hollow cross-section containing spaced guide tracks on the outer side facing the jib (10) in which guide components of the inner end (8) of the jib (10) engage and are positively held transversely to the direction of movement.
