PROBLEM TO BE SOLVED: To provide a washer nozzle capable of effectively expanding an injection range of washer fluid while having a simple structure.SOLUTION: A washer nozzle includes a nozzle body and a nozzle housing. The nozzle body has an inflow port 47, a recess formed with a flow path MS and auxiliary flow paths SS1 and SS2 in which cleaning fluid circulates, and an injection port 48. The injection port 48 has an aperture area which becomes larger to the outside. A pair of protrusion 71a and 71b are formed in the upper/lower and right/left inner walls of the injection port 48, and an aperture cross-sectional shape is formed in a nearly X shape. The protrusion 71a disperses the flow of the cleaning fluid in the vertical direction, and the protrusion 71b increases the speed of the flow of the cleaning fluid. The cleaning fluid is injected from the injection port in a state of being dispersed in the vertical direction, and an injection pattern becomes wiser in the vertical direction than a conventional one.SELECTED DRAWING: Figure 6
【課題】簡単な構造でありながら、ウォッシャ液の噴射範囲を効果的に拡大し得るウォッシャノズルを提供する。【解決手段】ウォッシャノズルは、ノズル体とノズルハウジングを備える。ノズル体は、流入口47と、洗浄液が流通する主流路MSおよび副流路SS1,SS2が形成される凹部と、噴射口48を有する。噴射口48は、外部に向かうに従い開口面積が大きくなる。噴射口48の上下・左右の内壁には、一対の凸部71a,71bが形成されており、開口断面形状が略X字形に形成されている。凸部71aは洗浄液の流れを上下方向に分散させ、凸部71bは洗浄液の流れを増速させる。洗浄液は、上下方向に分散された状態で噴射口から噴射され、従来よりも噴射パターンが上下方向に広くなる。【選択図】図6
