Abstract
An article conveying facility in which an article is conveyed by a conveyance carriage travelling on a pair of left and right rails provided along a conveyance path. The article conveying facility includes a carriage driving apparatus that drives the conveyance carriage by utilizing a frictional force generated by contact with the conveyance carriage, and sensors that detect floating of the conveyance carriage with respect to the rails. The conveyance carriage includes a fin that contacts the carriage driving apparatus. The fin is provided so as to extend along the travelling direction of the conveyance carriage, at a lower position than the position of an upper surface of the rails. The sensors detect floating of the conveyance carriage with respect to the rails by detecting the fin.
