WIPER NOZZLE APPARATUS IMPROVING ASSEMBILITY

摘要

PURPOSE: A wiper nozzle device is provided to improve assemblability by having specific assembly directionality because non-circular cross sections are assembled to each other. CONSTITUTION: A wiper nozzle device comprises a check valve module(20), a hollow pipe(30), and a nozzle(40). The check valve module makes washer liquid flow in one direction to prevent the backflow of the washer liquid. The hollow pipe is press-fitted in the check valve module. The nozzle is press-fitted in the top of the hollow pipe and sprays the washer liquid transferred from the hollow pipe to a glass. A coupling face of the check valve module and the hollow pipe is a non-circular cross section. A coupling face of the nozzle and the hollow pipe is a non-circular cross section.
