Abstract: The present invention provides sunshade apparatuses for automobile. An awning (12) is mounted above roof carry bars (10) of a vehicle. Within seconds of manual operation, the awing can either be retracted to occupy a small area typically 0.7×8 feet or be fully extended to generate a large rectangular shade area typically 7×8 feet above the automobile roof. If front part of the awning is made of a semi-transparent material for safe driving consideration of not blocking traffic lights, the awning may be manually retracted or extended by a driver within seconds even when the driver is driving. The sunshade apparatuses comprise multi-parallelogram shaped supporters (16). These supporters are extendable and retractable along the direction of vehicle width. Awning ribs (14) or awning rollers are perpendicularly mounted on the multi-parallelogram shaped supporters.
