PROBLEM TO BE SOLVED: To provide a conveyor chain capable of reducing the number of parts by forming a loading part of a chain link constituting the conveyor chain of one member and devising it to hold a rotatable ball in a cavity part formed on the loading part and capable of easily carrying out assembly, disassembly, removal of the ball, etc. SOLUTION: This conveyor chain 1 has a plurality of hinge parts 4, 5 formed on both side edges of the article loading part 3 and the plurality of chain links 2 having links formed on a lower surface of the loading part are endlessly connected to each other adjacent to each other by a hinge pin 7. A roughly U-letter shaped cutout part 8 having a recessed part 9 to be a one side receiver part of the free ball 11 inside is formed between the hinge parts 5, 5 formed on one side edge of the loading part 3, and the free ball 11 is fitted and held free to rotate in the cavity part 10 formed of this cutout part 8 and the hinge part 4 of the adjoining chain link.
