Before a moving member that moves along a moving path stops, an article transport facility starts protrusion control by which a moving support portion that is provided on the moving member is moved so as to protrude toward a fixed support portion, and thereafter the article transport facility appropriately determines whether or not to continue the protrusion control. Upon the moving member reaching a protrusion start position, the protrusion control is started so that the moving support portion is moved to protrude, even if the moving member has not stopped. After the moving member has reached a position at which a detection unit that is fixed to the moving member can detect a detection target member that is provided on the fixed support portion, the execution of the protrusion control is continued as long as the detection unit is detecting the detection target member.
