PROBLEM TO BE SOLVED: To provide a link structure which positively links a hook of a carriage traveling by remote control to an engaging portion of a passenger seat unit, and positively maintains the linkage. SOLUTION: The link structure is formed of the hook 1 which is held on a driving (C) side and carries out derricking operation by an appropriate derricking means 4, and an engaging portion 2 which is held on a driven (U) side and allows the hook 1 to be linked thereto when the hook 1 carries out the derricking operation. The link structure is comprised of a link position detecting mechanism which includes an abutting portion 5, a stroke body 6, and a switch 7. The abutting portion 5 is arranged on the driven (U) side, for directing its tip toward the driving (C) side. The stroke body 6 is arranged on the driving (C) side, for abutting its tip on the abutting portion 5, and then receding corresponding to advancement of the abutting portion 5. The switch 7 is arranged on the driving (C) side, for activating the derricking means 4 upon receding of the stroke body 6. COPYRIGHT: (C)2003,JPO
