1. A carrier device comprising a coupling mechanism that couples an automatic controlled vehicle to a carriage,
the coupling mechanism comprising:
a first roller disposed on the carriage so as to be rotatable around a first axial line extending in a vertical direction;
a second roller disposed on the carriage at an interval from the first roller in a horizontal direction, so as to be rotatable around a second axial line extending in the vertical direction;
a third roller disposed on the carriage so as to be rotatable around a third axial line extending in a same direction as the first axial line, independent of the first roller;
a fourth roller disposed on the carriage so as to be rotatable around an axis extending in a same direction as a direction in which the second axis extends, independent of the second roller;
a guide rail section disposed on the automatic controlled vehicle, the guide rail section including a pair of rail members extending in the horizontal direction, the pair of rail members being spaced apart from each other via a gap into which the first roller and the second roller can enter, and the guide rail section inhibiting relative movement between the automatic controlled vehicle and the carriage in a state where the first roller and the second roller are inserted into the gap;
a lock member provided in the automatic controlled vehicle so as to be movable between a first position and a second position, the lock member being sandwiched between the third roller and the fourth roller when the lock member is moved from the first position to the second position, and the lock member inhibiting relative movement between the automatic controlled vehicle and the carriage in a state where the lock member is sandwiched between the third roller and the fourth roller; and
an actuator which moves the lock member between the first position and the second position.
