It will move to position 2. A stopper (not shown) is provided so that the drive unit 50 cannot move further when it reaches the position A2, so that the drive mechanism 520 does not disengage from the rack seat 40.

Next, when the hand is released from the sliding door 1a, the sliding door 1
a is a driving force (spring force accumulated in the spring mechanism 520a) applied to the driving mechanism 520 from the open position to the closed position, whereby the gear mechanism 510 rotates on the rack seat 410 and closes itself. . At that time, the damper 520
Since the release of the spring force is adjusted by b, the moving speed of the sliding door 1a is suppressed and the sliding door 1a can move toward the closed position. The drive mechanism 520 is given an initial load at the closed position of the sliding door 1a, so that the drive mechanism 520 can surely close itself.

According to this embodiment (1), the interlocking sliding door unit 1 is opened by opening one sliding door 1b or 1a.
It is possible to open adjacent sliding doors 1a or 1b by interlocking with 10, and if the opening is stopped, the self-closing sliding door unit 150 can self-close together with the adjacent sliding doors.
