본 발명은 고압의 가스를 저장하는 압력 용기에 관한 것으로서, 보다 상세하게는 고압의 가스를 저장하는 압력 용기에서 가스 누출에 취약한 노즐부의 기밀성을 확보하기 위한 구조 및 이러한 노즐부를 포함하는 압력 용기에 관한 것이다. 이를 위해, 본 발명에서는 압력 용기의 내벽면을 형성하는 용기 몸체에 결합되며, 압력 용기 내외로 가스가 유동할 수 있는 내부 유로가 형성된 노즐 몸체 및 상기 노즐 몸체의 하부에 체결되는 록커를 포함하는 구조이며, 록커의 경사진 가압단부에 의하여 록커의 체결력에 의한 경사면에서의 실링과 함께 록커 내측에서 실링부재에 의한 이중 실링을 제공하도록 구성된다. A pressure vessel for storing high-pressure gas has a structure including: a nozzle body which is coupled to a vessel body that defines an inner wall surface of the pressure vessel, and has an inner flow path through which gas flows inside and outside of the pressure vessel; and a locker which is fastened to a lower portion of the nozzle body, and the structure is configured to provide dual sealing including sealing at an inclined surface by fastening force of the locker generated by an inclined pressing end of the locker, and sealing in the locker by sealing members.
