Can be supplied. As a result, efficient supply of the cleaning liquid W to the wiping surface G is realized.

Next, characteristic effects of the present embodiment will be described.
(4) The cowl top panel 53 is provided with a protruding portion 93 extending above the low back portion L (the wiper blade 72 of the second wiper 51B), and the washer nozzle 52 is provided on the protruding portion 93. According to this configuration, the cleaning liquid W ejected from the washer nozzle 52 can be hardly blocked by the wipers 51A and 51B in the normal standby state. Therefore, the cleaning liquid W can be efficiently supplied to the wiping surface G while reducing the air resistance when the vehicle 10 travels by disposing the wipers 51A and 51B close to the cowl top panel 53.

  (5) Since the washer nozzle 52 is provided on the extended front end surface 93a of the protruding portion 93 (the end surface on the wiping surface G side of the cowl top panel 53), the washer nozzle 52 is easily oriented toward the wiping surface G. As a result, the cleaning liquid W can be efficiently supplied from the wiping surface G. In addition, the appearance of the vehicle is improved with no protrusion feeling compared to the case where the washer nozzle 52 is provided on the upper surface of the protruding portion 93 (the upper surface 91 of the cowl top panel 53).

  (6) The protruding portion 93 is located in a gap between the wiper facing surface 92 of the cowl top panel 53 and the tip connecting portion 63 of the wiper arm 61 (first wiper 51A). As a result, the upper surface 91 of the cowl top panel 53 and the upper surface 61b of the distal end connecting portion 63 are substantially flush with each other, which can contribute to further reduction in air resistance when the vehicle 10 is traveling.

In addition, you may change each said embodiment as follows.
In the first embodiment, the washer nozzle 15a provided in the protruding portion 43 sprays the cleaning liquid Wa toward the wiping range Sa of the first wiper 14A, and the other washer nozzle 15b is the wiping range of the second wiper 14B. The cleaning liquid Wb may be sprayed toward Sb.

  In this case, since the washer nozzle 15a on the driver's seat side is disposed in the vicinity of the pivot axis Pa on the driver's seat side, when the cleaning liquid Wa is supplied to the wiping range Sa wiped by the first wiper 14A on the driver's seat side, The cleaning liquid Wa can be sprayed toward the longitudinal direction of the first wiper 14A at a predetermined wiping position. As a result, it is also possible to supply water with spreading in the longitudinal direction of the first wiper 14A. In the case where the tandem wiper of the first embodiment is an opposing wiper of the same type as the second embodiment, the passenger seat side washer nozzle 15b is disposed in the vicinity of the passenger seat side pivot shaft Pb. Even if the washer nozzle 15b is configured to spray the cleaning liquid Wb toward the wiping range Sb of the second wiper 14B, the same water landing as described above can be obtained.

  -In the said 2nd Embodiment, although the protrusion part 93 was formed in the length from the low back part L to the bending part 64 of the wiper arm 61 in the vehicle width direction, it corresponds to the low back part L in addition to this, for example It may be formed with a length in the vehicle width direction.

Further, the protruding portion 93 may be omitted from the cowl top panel 53 of the second embodiment, and the washer nozzle 52 may be provided at a position corresponding to the low back portion L on the wiper facing surface 92.
In the second embodiment, the protruding portion 93 may be extended to above the wiper blade 62 in the low back portion L. According to this configuration, the washer nozzle 52 can be brought closer to the wiping surface G, and as a result, the cleaning liquid W can be efficiently supplied to the wiping surface G.

  In the second embodiment, the first wiper 51A having the bent portion 64 in the wiper arm 61 is used as the wiper on the driver's seat side, and the second wiper 51B in which the wiper arm 71 is linearly formed is used as the wiper on the passenger seat side. Although the seat-side wiper has a preferred configuration in which the wiper is wiped as quickly as possible, the configuration may be reversed.

  -In each above-mentioned embodiment, you may change suitably the number of washer nozzles 15a, 15b, and 52 according to composition.
