The present invention relates to a coupling adaptor for a gas container, including a body with a fuel spray pipe being extending towards one side; a gas container coupling portion formed with a gas supply path communicating with the fuel spray pipe, and provided on one side of the body such that a portion is exposed outwardly from the body and the gas container is selectively coupled thereto; and an air-tight sealing portion provided in an inlet side of the gas supply path to prevent the gas supplied from the gas container, which is coupled to the gas container coupling portion, from being leaked outwardly from the gas supply path, and having a plurality of air-tight sealing members which selectively come into contact with a nozzle depending upon the nozzle shape provided on the gas container. Even though the gas containers of various shapes are coupled to the single coupling adaptor, air-tight sealing can be achieved to prevent the gas from being leaked. |
