An article transport facility comprising: a transport conveyor configured to load and transport a container (C1, C2) storing an article to a transport location (P1, P2); and a weighing device installed at the transport location (P1, P2); wherein the weighing device includes a support portion for supporting the container (C1, C2) and a measuring portion configured to measure a weight of the container (C1, C2) supported by the support portion, the article transport facility is configured to be able to perform a state change between a withdrawn state in which the support portion is withdrawn downward relative to a transport surface of the transport conveyor and a protruding state in which the support portion protrudes upward relative to the transport surface, by moving the support portion and the transport conveyor relative to each other in a vertical direction, and when a direction that is orthogonal in the view along the vertical direction with respect to a transport direction in which the transport conveyor transports the container (C1, C2) is a width direction, one side in the width direction is a first side in the width direction, and a side opposite thereto is a second side in the width direction, characterized in that a support surface of the support portion for supporting the container (C1, C2) is inclined such that one of a plurality of corner portions located at corners of the container (C1, C2) is lower than all the other corner portions in a view along the vertical direction, wherein the support surface is inclined downward toward a downstream side in the transport direction, and is inclined downward toward the first side side in the width direction. a transport conveyor configured to load and transport a container (C1, C2) storing an article to a transport location (P1, P2); and a weighing device installed at the transport location (P1, P2); wherein the weighing device includes a support portion for supporting the container (C1, C2) and a measuring portion configured to measure a weight of the container (C1, C2) supported by the support portion, the article transport facility is configured to be able to perform a state change between a withdrawn state in which the support portion is withdrawn downward relative to a transport surface of the transport conveyor and a protruding state in which the support portion protrudes upward relative to the transport surface, by moving the support portion and the transport conveyor relative to each other in a vertical direction, and when a direction that is orthogonal in the view along the vertical direction with respect to a transport direction in which the transport conveyor transports the container (C1, C2) is a width direction, one side in the width direction is a first side in the width direction, and a side opposite thereto is a second side in the width direction, characterized in that a support surface of the support portion for supporting the container (C1, C2) is inclined such that one of a plurality of corner portions located at corners of the container (C1, C2) is lower than all the other corner portions in a view along the vertical direction, wherein the support surface is inclined downward toward a downstream side in the transport direction, and is inclined downward toward the first side side in the width direction.
