PROBLEM TO BE SOLVED: To inject a cleaning liquid from an injection hole, without using a heater.SOLUTION: In a washer nozzle 40, a first water repellent part 52 for constituting an inner peripheral surface 50A of a first flow passage 50 in the washer nozzle 40, a second water repellent part 62 for constituting an inner peripheral surface 60A of a second flow passage 60 and a third water repellent part 72 for constituting an inner peripheral surface 70A of a third flow passage 70, are constituted of a material (a fluororesin) having water repellency. Thus, when liquid such as water tries to infiltrate into the first flow passage 50 (the second flow passage 60 and the third flow passage 70) from a first injection hole 54 (a second injection hole 64 and a third injection hole 74), the liquid is repelled by the first water repellent part 52 (the second water repellent part 62 and the third water repellent part 72). Thus, even when the first injection hole 54 (the second injection hole 64 and the third injection hole 74) is flooded with the liquid such as the water, the liquid can be restrained or prevented from being sucked in the first flow passage 50 (the second flow passage 60 and the third flow passage 70) from the first injection hole 54 (the second injection hole 64 and the third injection hole 74).

    【課題】ヒーターを用いることなく洗浄液を噴射孔から噴射する。【解決手段】ウォッシャノズル40では、ウォッシャノズル40における第1流路50の内周面50Aを構成する第1撥水部52、第2流路60の内周面60Aを構成する第2撥水部62、及び第3流路70の内周面70Aを構成する第3撥水部72が、撥水性を有する材料(フッ素樹脂)で構成されている。このため、水等の液体が第1噴射孔54(第2噴射孔64、第3噴射孔74)から第1流路50(第2流路60、第3流路70)内へ浸入しようとすると、当該液体が第1撥水部52(第2撥水部62、第3撥水部72)によってはじかれる。これにより、水等の液体に第1噴射孔54(第2噴射孔64、第3噴射孔74)が被水した場合でも、第1噴射孔54(第2噴射孔64、第3噴射孔74)から第1流路50(第2流路60、第3流路70)内へ当該液体が吸い込まれることを抑制又は防止できる。【選択図】図1
