Abstract: A wiper apparatus is improved in wiping performance, and can suppress a disturbance due to cleaning liquid in a driver's field of view. Each cleaning liquid W1 and W2 is jetted from four forward-side injection nozzles and four backward-side injection nozzles in a direction opposite to the wiper blade 20, and toward injection-target locations, and a distance between the wiper blade 20 and an injection-target location for cleaning liquid W1 and W2 on the opposite side from a center of a swinging motion of the wiper blade 20 in a wiping direction of the wiper blade 20 is larger than a distance between the wiper blade 20 and an injection-target location for cleaning liquid W1 and W2 on the same side as the center of the swinging motion of the wiper blade in the wiping direction of the wiper blade 20.
Abstract: injection positions (A2, B2, and C2) toward which washer liquids (W) are injected from the forward-side injection nozzles (A1, B1, and C1) and injection positions (D2 and E2) which washer liquids (W) are injected from the backward-side injection nozzles (D1 and E1) 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 (12) 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.
Abstract: A washer apparatus 50 is provided to a coupling portion CN between a blade rubber 20 and a holder member 30, and has a length in a longitudinal direction of the blade rubber 20, which is set to be shorter than that of the blade rubber 20 in the longitudinal direction, and inner-peripheral-side-oriented injection nozzles 53a and 55a and an outer-peripheral-side-oriented injection nozzle 54a have openings oriented to respective ends of the blade rubber 20 in the longitudinal direction.
