PROBLEM TO BE SOLVED: To provide a joining structure, by which the airtightness of compressed air charged in a coating liquid storage chamber is obtained and, at the same time, which has high productivity. SOLUTION: In the joining structure between the coating liquid storage chamber, in which gas assisting the discharging of the coating liquid by pressure is charged under its compressed state together with the coating liquid, and an airtight member mounted on the tubular opening with this coating liquid storage chamber under the condition that their joining part becomes airtight, a fitting projected part realizing an overriding fitting is formed at the joining part between the two members and, at the same time, a joining structure, in which the diameter of a peripheral adjusting part formed on the outer wall of the airtight member and abutted against the inner wall of the opening part of the coating liquid storage chamber locating the more inner part of the coating liquid storage chamber than the fitting projected part is made smaller than the minimum inner diameter of the fitting projected part formed in the joining part of the coating liquid storage chamber, is realized.
