The invention provides a wind-resistant and sun-shading curtain, and belongs to the technical field of machinery. The wind-resistant and sun-shading curtain solves the problem that the available curtain is poor in wind resistance. The wind-resistant and sun-shading curtain comprises curtain rolling cloth, a window cover and a pipe rolling assembly, wherein the pipe rolling assembly is assembled in the window cover, and wound with the curtain rolling cloth; each of the two ends of the window cover is fixedly connected with an edge rail downwards; a longitudinal opening is formed on one side, facing toward the curtain rolling cloth, of each edge rail; two clamping strips arranged symmetrically are mounted in each edge rail longitudinally; a gap is formed between every two clamping strips; upper ports of the gaps are communicated with the window cover; the two side edges of the curtain rolling cloth extend into inner cavities of the edge rails, and are fixedly connected with flexible positioning pieces transversely after penetrating through the longitudinal openings of the edge rails and the gap between every two clamping strips respectively; two annular grooves formed symmetrically are formed in the pipe rolling assembly; when the curtain rolling cloth is wound on a rolling pipe, the two side edges of the curtain rolling cloth are wound and located at the corresponding annular grooves respectively; and the outer diameter of each positioning piece is greater than the width of the gap between every two clamping strips. The wind-resistant and sun-shading curtain has the advantages of stable and reliable structure, good guidance quality and high wind resistance.
