ABSTRACT:
A terminal rail system for an escalator includes an escalator step including a step front roller and a step rear roller, an upper guide rail for guiding the step front roller, a lower guide rail for guiding the step rear roller, a semicircular inner casing and outer casing, the inner casing being engaged to the lower guide rail, at a curved portion of the lower guide rail the escalator step changing a proceeding level, and at least one end portion of each of the inner casing and outer casing being separated from a corresponding one thereof for thereby reducing an impact caused by the step rear roller. The terminal rail system flexibly buffers the respective impacts caused by the step rear roller for thereby considerably relieving the vibration and noise.
