PROBLEM TO BE SOLVED: To provide an expansion gate with a good appearance, which can enhance assembling workability and fixing strength. SOLUTION: A fixing and connecting component 7 is mounted in a predetermined position of a muntin 6 only by pushing the fixing and connecting component 7 into the inside of the opening 62 of the muntin 6 in the state of positioning a forward protruding portion 751 of the fixing and connecting component 7 in the first notched portion 65 of the external protruding piece portion 63 of the muntin 6. Thus, the fixing and connecting component 7 can be fitted into the muntin 6 through one action, and the workability of mounting work can be improved. Furthermore, since the first notched portion 65 of the external protruding piece portion 63 of the muntin 6 cannot be seen from the outside by being covered with a connecting component body portion 71 in the state of fitting the fixing and connecting component 7, the designability of the appearance of the expansion gate can be improved.
