PROBLEM TO BE SOLVED: To provide a chain conveyor system inhibiting pulsation occurring in a linear traveling part and realizing miniaturization and low noise of the system. SOLUTION: In a chain conveyor system comprising at least one streak of roller chain circulatingly traveling along a predetermined travel passage, the roller chain is laid on turning members in both ends of a circulation track, a magnetic spiral drive mechanism is arranged in at least one location on the linear traveling part of the circulation track, and an attraction member attracted to a spiral magnetic part of the magnetic spiral drive mechanism is fixedly attached to an attachment of the roller chain or a slat laterally laid on the roller chain.
