The present invention relates to a foreign matter inflow prevention cover of an inlet cap of a urea water tank for a vehicle, capable of simplifying a urea water filling process. According to the present invention, the foreign matter inflow prevention cover is sealed to prevent inflow of a foreign matter by an inlet (1) of a urea water tank of a vehicle, an inlet cap (2) coupled to the inlet to prevent leakage of urea water, and a coupling portion formed by surrounding and coupling the entire outer surface of the inlet cap (2) and the inlet (2) of the urea water tank. The foreign matter inflow prevention cover (C) comprises: a protection head part (100) formed in a cylindrical shape with an opened lower part corresponding to a shape of the inlet cap to surround the upper and outer circumferential surface of the inlet cap (2); a locking sealing ring part (200) closely corresponding to the lower circumference of the inlet cap (2) along the lower inner circumference of the protection head part (100) to realize sealing and locking, and formed with a predetermined angle to facilitate coupling and decoupling the protection head part (100) to and from the inlet cap (2); and a flexible sealing part (300) having a lower part formed around the lower outer side of the protection head part (100) having the locking sealing ring part (200) formed therein, and dual-injection molded by a soft material to bend elastic force toward the central axis of the inlet (1) in order to be closely attached to the outer circumferential surface of the inlet (1) of the urea water tank.

    본 발명은 자동차용 요소수 탱크 주입구 캡에 관한 것으로, 이물질 유입방지 커버는 자동차의 요소수 탱크의 주입구(1)와 주입구에 결합되어 요소수의 누출을 방지하도록 마련된 주입구 캡(2)과 상기 주입구 캡(2)과 주입구(1)의 외면 전체를 감싸 결합되어 요소수 탱크의 주입구(1)와 주입구 캡(2)의 결합부위를 통해 이물질 유입이 차단되도록 밀폐하는 이물질 유입방지 커버에 있어서, 상기 이물질 유입방지 커버(C)는 주입구 캡(2)의 상부면과 외주면을 감싸도록 주입구 캡 형상에 대응되게 하부가 개방된 원통형상으로 형성된 보호헤드부(100)와; 상기 보호헤드부(100) 하부 내주연을 따라 상기 주입구 캡(2)의 하부 외주연에 밀착대응되어 밀폐 걸림되도록 형성되고, 상기 보호헤드부(100)가 주입구 캡(2)으로부터 결합 및 해제가 용이하도록 일정각도로 경사지게 형성된 걸림밀폐환부(200)와; 상기 걸림밀폐환부(200)가 형성된 상기 보호헤드부(100) 하부 외측 둘레를 따라 하부가 개방되게 형성되고, 요소수 탱크의 주입구(1) 외주면에 밀착되응되도록 탄성력이 상기 주입구(1) 중심축으로 오므라지게 연질로 이중 사출 형성되는 플렉시블 실링부(300);로 형성된 것을 특징으로 하는 자동차용 요소수 탱크 주입구 캡에 관한 것이다.
