PROBLEM TO BE SOLVED: To decrease a dead space within a storage part by improving the layout relation between an opening/closing machine and an opening/closing body such as a shutter curtain housed in a wound state within the storage part such as a shutter case. SOLUTION: The respective inside surface parts of a top board 5, a back board 7, and a front board 13 are located on an outer diameter line Dc wherein clearance C is added to the maximum winding diameter Dm of the shutter curtain 19. The inside surface part of a bottom board 9 is located on a perpendicular Lo through a winding center O in such a manner as to have an insertion gap I from the lower end of a minimum winding diameter Ds below the maximum winding diameter Dm. The shutter case 3 is formed by having an internal corner part 23 in the joint section between the bottom board 9 and the back board 7. The opening/closing machine 35 is detachably disposed outward relative to the outer diameter line Dc in the corner part 23. A guide rail 17 for guiding the shutter curtain 19 is located between the perpendicular Lo through the winding center O and a perpendicular Lf through the maximum winding diameter Dm, and an introduction port 17a is disposed in the bottom board 9.
