The main frame is an endless conveyor path whose horizontal projection surface is an arc, and which is tilted in the vertical direction and has an outgoing path on the top surface, an inverted portion at the end, and a return path on the bottom side. There is one in which a large number of fan-shaped steps are arranged in a conveyance path with the step shafts connected to inner and outer step chains having outer ends. In addition, in the curved S force rake, the inner and outer step chains are respectively meshed with the inner and outer full chain gears provided in the upper and lower reversible parts and have mutually different diameters, and the upper and lower Drive the inner and outer gears on one side of the reversing section, rotate the inner step chain at a smaller radius than the outer step, invert the step shaft and the step tread in a circular shape, and turn the step.
