PROBLEM TO BE SOLVED: To provide an opening/closing device which dispenses with a rail and reduces the size of a storage space for a door body. SOLUTION: A member 13, which is provided in the state of being laid across an opening 3, is constituted by bendably coupling short members 15 and 16 together in a zigzag manner; a synchronous link 17 is constituted by bendably coupling link rods 18 together in a zigzag manner in the direction opposite to the short members 15 and 16; the short members 15 and 16 and the link rods 18 are pivotally mounted, respectively; and an end of the link rod 18, which is located at one end of the synchronous link 17, is made movable along a guide rail 22.
