PROBLEM TO BE SOLVED: To provide a conveyor system for metal strip which, despite of a relatively simple structure, can suppress meandering of a metal strip and particularly can effectively suppress pinch roll-derived meandering of the metal strip. SOLUTION: The conveyor system for metal strip includes a roller table constituted of a plurality of conveying rolls. At least one of the conveying rolls, i.e., a covey roll A, includes a pair of roll bodies a<SB>L</SB>, a<SB>R</SB>arranged symmetrically with respect to the center of a pass line. The axial line of both the roll bodies a<SB>L</SB>, a<SB>R</SB>on the end side closer to the center of the pass line in the widthwise direction of the roller table is inclined toward the upstream side of the line. In a support shaft that rotatably supports both the roll bodies a<SB>L</SB>, a<SB>R</SB>, a magnet B is provided on a support shaft portion located on the inner side of the roll body. According to the constitution, the out-of-plane deformation of the metal strip can be prevented, and, in particular, pinch roll-derived meandering of the metal strip can be effectively prevented.
