ABSTRACT:
A conveyor apparatus is provided that is free of a pulsing motion in the circulating chains so as to provide a comfortable ride quality on its steps. The conveyor apparatus includes a step guide rail, a plurality of steps, a step chain, and a chain driving mechanism for driving the step chain. The chain driving mechanism includes a rotating and driving unit, a driving sprocket which is rotated by a driving force given by the rotating and driving unit, and a circulating chain for giving a thrust to the step chain. The circulating chain has chain links and hinges that are to be connected to the adjacent chain links. The chain link includes a placing surface on which the step roller is placed, and pressing surfaces that are in contact with step rollers.
