PURPOSE: A connecting structure of an air-tight container is provided to prevent a cover form detaching by external force. CONSTITUTION: A connecting structure of an air-tight container includes a container main body(10), a first support protrusion(20), a second support protrusion(30), a cover member(40), a coupling protrusion, and a coupling hole. The first support protrusion is projected along an external edge of a container main body. The second support protrusion is projected from an external edge of a container main body which the first support protrusion is formed. The cover member selectively seals a space part by being combined to be detachable/attachable on container main body. The cover member has a combining wing(42) which is combined and rotates to container main body to edge side. A hook projection is formed in inside of a coupling wing. The hook projection supports the first support protrusion when a combining wing is combined to a container main body. The hook hole is formed in combining wing. The first support protrusion is inserted into a hook hole when a combining wing is combined to the container main body.
