To provide a widening part movement mechanism that can easily unload a large cargo.SOLUTION: When a wire is pulled up by an actuator in a door closed state that a lower foldable door is closed, a crank part rotates and one end part thereof presses an innermost plate of a latch reception part, whereby a joint between an upper door and a lower door is separated from a guide part and upper and lower foldable doors are refracted, and the upper and lower foldable doors gradually move to an open state while a lifting part lifts along the guide part.SELECTED DRAWING: Figure 26

    【課題】大型の貨物を容易に積み下ろしできる拡幅部移動機構を提供する。【解決手段】下折畳扉が閉じられた扉閉状態において、アクチュエータによってワイヤーが引き上げられた場合に、クランク部が回動して一端部がラッチ受部の奥板を押圧することにより、上部扉と下部扉の繋ぎ目がガイド部から離隔して上下折畳扉が屈折し、昇降部が前記ガイド部に沿って昇降しながら前記上下折畳扉が次第に扉開状態に移行する。【選択図】図26
