The screen has a main body and two lateral portions. The main body is wound on the screen-stretching portion and the intermediate portion of the roller and has opposite ends. The lateral portions are connected respectively to the opposite ends of the main body and are wound respectively on the end portions of the roller.

1 . A sunshade comprising:
 a roller extending along an axial direction and having an intermediate portion, two end portions extending respectively from axially opposite ends of said intermediate portion in the axial direction, and a screen-stretching portion disposed on an outer surrounding surface of said intermediate portion; and   a screen having a main body that is wound on said screen-stretching portion and said intermediate portion of said roller and that has opposite ends in the axial direction, and two lateral portions that are connected respectively to said opposite ends of said main body and that are wound respectively on said end portions of said roller.   
     
     
         2 . The sunshade as claimed in  claim 1 , wherein said screen-stretching portion surrounds said intermediate portion of said roller with an axial length equal to that of said intermediate portion, said screen-stretching portion having a pair of side parts that are opposite to each other in the axial direction, and a middle part that interconnects said side parts, and outer diameter of said screen-stretching portion increasing gradually from said side parts toward said middle pat. 
     
     
         3 . The sunshade as claimed in  claim 1 , wherein said screen-stretching portion of said roller has an end connected integrally to a longitudinal edge of said main body of said screen, and an opposite end connected fixedly to and wound on said outer surrounding surface of said intermediate portion of said roller.
