PROBLEM TO BE SOLVED: To provide an opening/closing device that facilitates assembly work for a shutter curtain and a winding part, as well as protection and maintenance of components disposed on the winding part and subject to maintenance work.SOLUTION: A winding part 6 includes a mounting part 64 for a component subject to maintenance and a component 65 subject to maintenance placed on the mounting part for a component subject to maintenance, the mounting part being disposed between a wheel on a first side at the first side of a rotary central shaft 61 and a wheel on a second side at the second side of the rotary central shaft. An opening/closing body 4 wound by the winding part includes a connecting part 30 connected to a wheel 62, a slat part (opening/closing part) 10, and a sheet member 40 having one end connected to the connecting part and the other end connected to the slat part. The sheet member 40 covers the mounting part for a component subject to maintenance when the slat part totally closes an opening 13, and forms an opening 80 for maintenance work by rotating the wheel in a direction to feed out the opening/closing body further from the totally closed state of the opening/closing body.SELECTED DRAWING: Figure 4 |
