injection positions (A, B, and C) toward which washer liquids (W) are injected from the forward-side injection nozzles (A, B, and C) and injection positions (Dand E) which washer liquids (W) are injected from the backward-side injection nozzles (Dand E) are alternatively shifted in the longitudinal direction of the blade rubber. Therefore, in wiping-out motion of the blade rubber for one reciprocation, the front glass () can uniformly get wet, the total number of injection nozzles can be made less than ever, the consumption amount of washer liquid (W) at the time of reciprocating wiping-out motion of the blade rubber can be reduced, power consumption of the washer pump can be reduced, and the size of the washer pump can be decreased.

Wiper blade

A nozzle unitwhich jets washer fluid toward a windshield is fixed to an arm piecewhose front end side is fitted to a hook fixing member. As a result, the nozzle unitcan be fixed without using the fitting member adopted in the conventional case, and located closer to the hook fixing member. This reduces a positional shift of the nozzle unitrelative to the wiper bladeto the minimum, thus stabilizing the injection-target locations of washer fluid on the windshield.
