Disclosed is a variable wiper structure for automobiles so that the trace of the blades varies by moving the 2nd wiper arm, and by fixing the blade pin-jointed to the slide groove. The structure comprises a slide groove (21) along the wiper arm(20); the 2nd pivot shaft(34) fitted in the wiper arm; blade(30) and the 2nd wiper arm(33); a blade(30) that has a projected slide support pin(31) and that is inserted into the slide groove (21) of the wiper arm(20) so that the 2nd wiper arm(33) can rotate; and a stopper(32) that is projected from both sides of the slide support pin(31) and slide fitted to the outer surface and that prevents the slide support pin(31) from rotating in the slide groove (21).
