PROBLEM TO BE SOLVED: To prevent hysteresis in a link device. SOLUTION: The link device is provided with a link plate 33 rotated/operated in normal and reverse rotation directions A, B by a drive device 29 and having drive groove parts 34, 35; driven members 31, 32 displaced accompanying with displacement of pin parts 31a, 32a slidably fitted to the drive groove parts 34, 35; and a control means 36 for controlling operation of the drive device 29. When the link plate 33 is rotated/operated from a first rotation position to a second rotation position at the normal rotation direction A side than the first rotation position, the link plate 33 is rotated/operated to the second rotation position and is stopped. Whereas, when the link plate 33 is rotated/operated from a third rotation position at the normal rotation direction A side than the second rotation position to the second rotation position, after the link plate 33 is rotated in a reverse rotation direction B and is passed through the second rotation position once, the link plate 33 is rotated in the normal rotation direction A and is stopped so as to return it to the second rotation position.
