Abstract (en)
An escalator system 11 has a plurality of steps 12 connected to chains 20 extending between upper sprocket wheels 18 disposed on an upper floor 15 and lower sprocket wheels 19 disposed on a lower floor 16, and travels along a circulating path while maintaining the steps 12 in horizontal posture through a transport region S5 for transporting users. The steps circulate with riding surfaces 22 thereof constantly facing upward, which allows the escalator system 11 to be made thin. <IMAGE>
