PROBLEM TO BE SOLVED: To provide a simultaneous opening/closing mechanism for a double hinged door which has high durability and a simple structure and can be installed while saving the space, and the double hinged door.SOLUTION: A simultaneous opening/closing mechanism 30 for a double hinged door in which a left door and a right door are opened outwardly to both left and right sides comprises: a pair of disc members 32a, 32b which are rotated in the same direction together with rotations of respective rotary shafts 31a, 31b of the left door and the right door; a link member 33 for transferring, to the rotation member 32b at a side of the right door, a rotating direction of the rotation member 32a at a side of the left door in the pair of disc members 32a, 32b while inverting the rotating direction; and a shock absorbing device 34 which is provided in one end portion of the link member 33 and prevents the left door and the right door from being opened to opposite sides by excessive motion or suppresses generation of impulse sound or the like in closing. Thus, automatic opening/closing can be performed in a simple structure. |
