PURPOSE: A washer liquid injection device of a vehicle is provided to execute an injection function by upwardly projecting only when injection is obstructed by foreign matters stuck in an injection nozzle, and to simultaneously discharge a washer liquid and the foreign matters to the outside by using the pressure instantaneously rising to a pipe line of the injection nozzle when the injection nozzle is clogged by the foreign matters and to be normally restored if the pressure of the injection nozzle is lowered. CONSTITUTION: A washer liquid injection device of a vehicle includes a nozzle body(110) forming a thread part(112) to the lower end and a projected hole(114) to the upper end; a telescopic nozzle(120) inserted in the nozzle body; a nozzle base(130) combined to the nozzle body; and a spring(128) inserted between the nozzle body and the telescopic nozzle, to elastically support the telescopic nozzle. The telescopic nozzle vertically moves through the projected hole. The telescopic nozzle forms a guide part(124), sliding according to the inner wall of the nozzle body, to the lower end, has a washer liquid injection port(122) to the top, and forms a foreign matter discharge outlet(126) to a side. The nozzle base has a washer liquid inlet(132) to the lower end. Foreign matters are discharged to the outside through the foreign matter discharge outlet while the telescopic nozzle is projected from the nozzle body as the internal pressure rises when the washer liquid injection port is clogged by the foreign matters. The telescopic nozzle forms inclination toward the foreign matter discharge outlet at the inner end, to easily discharge foreign matters. |
