Abstract
In an escalator with a high speed inclined section, steps are coupled in an endless manner and circulate. Driving roller shafts of the steps adjacent to each other are coupled with each other by a link mechanism. An interval between the driving roller shafts is changed as the link mechanism is transformed. An outer peripheral length change absorbing mechanism is provided in a reversing section of a circulation path of the steps. The outer peripheral length change absorbing mechanism absorbs a change in an outer peripheral length of a polygon, formed by connecting axes of the driving rollers with straight lines, while guiding movement of the driving rollers in the reversing section.
