ABSTRACT:
A wiper blade of the present invention comprises two or three blades for wiping. The blades are longitudinally parallel and have their bases integrated into each other. The bases have deflective portions on the longitudinal outer sides of the integral body of the bases, so that the deflective portions serve to deflect one of the two outmost blades backward when one blade is ahead of the other and the wiper blade is performing a wiping action. The wiper blade of the present invention has a smaller edge height than a conventional wiper blade of a single blade, so that the former wiper blade may be easier to deform in conformity with a surface to be wiped, enabling a more stable wiping action and having a lower air resistance.
