PURPOSE: To obtain a structure in which opening-closing operation is lightened and quietted and which has sufficient strength resisting outdoor use, durability and excellent appearance and can be made to travel along an inclined rail and in which a damaged panel can be exchanged easily, regarding a hinged shutter constituted by connecting vertically slender unit panels.

CONSTITUTION: Suspended wheels 11 are placed at central sections at the upper ends of unit panels 1, the adjacent unit panels 1, 1 are coupled by upper and lower pivotally attaching pairs 25, 26 formed among brackets 14, 16 and one side 2 under the state in which one sides of continuously connected vertical sides are fitted among the upper and lower brackets 14, 16 of the other vertical sides 3, and vertical clearances 27 are formed among the upper ends of one vertical sides and the upper brackets 14. The clearances are larger than the length of fit among the pins 17 and holes 22 of the lower pivotally attaching pairs. The adjacent panels can be displaced mutually in a stepped shape in the presence of the clearances, and can be mounted and demounted easily.
