An article transport facility comprising: a carriage sequence which is a plurality of transport carriages, for transporting articles, connected together along a travel path, the plurality of transport carriages being capable of traveling along the travel path; and a driving device for causing the carriage sequence to travel along the travel path; wherein each of the plurality of transport carriages includes a carriage main body, a wheel which rolls on a travel surface formed along the travel path, a first connecting portion provided to a forward end portion of the carriage main body, and a second connecting portion provided to a back end portion of the carriage main body, wherein the first connecting portion is connected to the second connecting portion of another transport carriage that is immediately in front so as to be pivotable about a carriage pivot axis extending along a vertical direction, characterized in that, the wheel is provided in the forward end portion of the carriage main body, wherein the wheel and the carriage pivot axis of the first connecting portion overlap with each other as seen along a carriage lateral direction, wherein each of the plurality of transport carriages includes a caster frame which is connected to the carriage main body such that the caster frame is rotatable about a wheel pivot axis which extends along the vertical direction when the transport carriage is in a horizontal attitude, and wherein the caster frame rotatably supports the wheel with a wheel rotation axis, which is a rotation axis of the wheel, located at a different position along a horizontal direction from the wheel pivot axis, when the caster frame is in a straight travel state in which the wheel rotation axis is located rearwardly of the wheel pivot axis and in which the wheel rotation axis is in an attitude that is parallel to the carriage lateral direction, the wheel and the carriage pivot axis overlap with each other as seen along the carriage lateral direction, wherein each of the plurality of transport carriage includes a restriction member for restricting movement of the carriage main body along the carriage lateral direction by contacting a guide rail provided along the travel path, each of the restriction members being provided to be rotatable about a restriction member pivot axis extending along the vertical direction with the restriction member pivot axis being located between the wheel pivot axis and the wheel rotation axis in the straight travel state as seen along the carriage lateral direction. a carriage sequence which is a plurality of transport carriages, for transporting articles, connected together along a travel path, the plurality of transport carriages being capable of traveling along the travel path;
