PROBLEM TO BE SOLVED: To provide an installation structure of a winding shaft storing case of a shutter device, capable of securing smooth rotation of a winding shaft having an end part supported by brackets, and stored inside the case. SOLUTION: The winding shaft 50 for winding and delivering a shutter curtain 30 for moving for opening and closing, is supported by the left-right brackets 51 and 52 having base parts 51A and 52A joined to an installation member 16 being an immovable member. The case 80 for storing the winding shaft 50 inside, is joined by a joining tool 82 only to projecting parts 51B and 52B arranged near the base parts 51A and 52A of the brackets 51 and 52. Thus, the case 80 and the brackets 51 and 52 are incompletely connected. Even if there is an error such as eccentricity in shafts 63 and 70 being a central shaft part of the winding shaft 50, the brackets 51 and 52 run out and move in the shaft direction of the winding shaft 50 with the base parts 51A and 52A as the center, and smoothly rotate the winding shaft 50.
