A carrier chain is provided which vibrates less when moving on the curved portion of the guide rail. The carrier chain can carry the article to be carried smoothly and in a more stable state, and can prevent the one-sided wear of the guide rail and the chain units. The carrier chain includes pawls which have an upwardly inclined bottom surface. The pawls are formed on both left and right sides of a base bed portion of chain units which make up the carrier chain. A distance which is relative to a support surface of a guide rail gradually increases from a proximal end side toward an extreme end. When the chain unit moves on a curved portion of the guide rail, and when the chain unit is inclined internally of the curved portion by the tension applied from the adjacent chain units before and behind, the bottom surface of the pawl, which is internal of the curved portion, comes in contact with the support surface in a substantially face-to-face contact state.
