Abstract
A conveyance device utilizing coupled wagons includes front and rear adjacent wagons and a pair of left and right coupling units coupling left and right side portions of the adjacent wagons. The coupling units are switchable between a coupled state in which the left and right side portions of the adjacent wagons are respectively allowed for relative horizontal rotations about vertical shafts and an uncoupled state. A first coupling control mechanism operating at least one of the coupling units is provided at a horizontal turn path section in a travel path. By the operation of the first coupling control mechanism, the conveying traveling body can enter the horizontal turn path section while the coupling unit on the inner side of the horizontal turn path section is in the coupled state and the coupling unit on the outer side of the horizontal turn path section is in the uncoupled state.
