Abstract: At a time of forming lip portions in upper and lower edge portions of an ejection port in a protruding manner, a nozzle for ejecting a washer fluid of a washer fluid ejection apparatus in a diffusion manner is structured such that a step surface is formed on an inner side surface such that protruding amounts of the lip portions are set to the same length with a protruding tip portion in a washer fluid ejection side of the lower lip portion positioned lower than a lower side edge portion of the ejection port. Accordingly, it is possible to make the ejected washer fluid substantially unaffected by the air flow during vehicle movement.

Abstract: At a time of forming lip portions 9e, 9f in upper and lower edge portions of an injection port 9d in a protruding manner, a nozzle for injecting a washer fluid of a washer fluid injection apparatus in a diffusion manner is structured such that a step surface 9i is formed on an inner side surface 9h such that protruding amounts of the lip portions 9e, 9f are set to the same size, a protruding tip portion in a washer fluid injection side of the lower lip portion 9f is positioned in a lower side than a lower side edge portion of the injection port 9d. Accordingly, it is possible to make the injected washer fluid hard to be affected by an air flow during traveling.
