Abstract

L'objectif de la présente invention est de permettre le couplage d'un coupleur mâle et d'un coupleur femelle, même si un désalignement dans la direction horizontale se produit entre le coupleur mâle et le coupleur femelle. Le dispositif de couplage comprend : une base fixe (42) ; un boulon de positionnement (45) s'étendant vers le bas à partir de la base fixe (42) ; et une base mobile (43) à laquelle le coupleur mâle (73, 83) est fixé et qui peut adopter un état de positionnement dans lequel la base mobile est positionnée à une position prédéterminée par le boulon de positionnement (45), et un état mobile dans lequel la base mobile peut se déplacer dans une direction horizontale, en se déplaçant vers le haut à partir de la position prédéterminée. Lors de l'adoption d'un état accouplé, la base mobile (43) et le coupleur mâle (73, 83) se déplacent tous les deux vers le haut à la suite de l'entrée en contact du coupleur femelle (74, 84) avec le coupleur mâle (73, 83) par le bas, ce qui permet de passer de l'état de positionnement à l'état mobile.
