<P>PROBLEM TO BE SOLVED: To provide a washer nozzle constituted of a simple nozzle of a structure having a self-excited oscillation flow passage. <P>SOLUTION: The nozzle 14 is formed in a spherical shape at an outer surface and rotatably installed by being pressed in an injection part 13 formed at a nozzle body 12, and an action chamber 23 of a specific height in the vertical direction of becoming the oscillation flow passage is formed inside. The action chamber 23 is formed in a rectangular shape at a specific width, and a jetting hole 26 for supplying a cleaning liquid is formed in a central part on the innermost side, and an outlet becomes a nozzle port 25 of expansively opening outward. An upper wall for forming the action chamber 23 forms eaves 27 by projecting outward from the nozzle port 25, presses down a diffusing flow of injecting outward from the nozzle port 25 from the upper side, narrows a range in the vertical direction of the diffusing flow, and performs the function of flattering the diffusing flow. <P>COPYRIGHT: (C)2013,JPO&INPIT |
