Abstract: A sun visor for an automobile window is formed integrally and has a shape matching that of the upper edge of an automobile window frame. The sun visor has an upper edge and two sides formed with a smooth combining portion, a bulgy and arc-shaped screening portion formed to extend downward from a lower section of the combining portion, and a glue sheet adhered on an inner side of the combining portion. A decorative bar is installed on the outer side of the combining portion and has opposite ends respectively covered with a protective member that has an inner side formed with an engage groove for receiving each end of the decorative bar and an upper edge formed with a stop surface resisting against the top edge of both the decorative bar and the combining portion. The decorative bar functions to beautify the external look of the sun visor.
