PROBLEM TO BE SOLVED: To provide a folding door connecting device having a self-closing function and a braking function when closing a door, in the folding door connecting device for connecting a suspender side door and a door end side door. SOLUTION: This folding door connecting device has gears 10A and 10B fixed to the suspender side door 1 and the door end side door 2. Central shafts 11A and 11B of these gears 10A and 10B are connected by a connecting plate 12. A spring 13 is arranged between one gear 10B and the connecting plate 12 so as to be screwed in when a door rotates in the opening direction. The other gear 10A and the central shaft 11A are connected via a one-way clutch 17 so as to transmit torque when the door rotates in the closing direction. A fluid frictional braking means is arranged on this central shaft 11A. COPYRIGHT: (C)2008,JPO&INPIT
