Claims

[Scope of utility model registration request]

A large number of steps are arranged vertically in series in the main frame and are arranged in an endless manner, and the driving wheels are engaged with the step chain and are connected to each other and move up and down relative to each other at the end of the main frame, and are fixed to the main frame. A second rule is arranged in an endless manner and forms an upper white part and a lower part at the end of the main frame for moving the steps up and down relative to each other, and guides the driving wheels and the driven wheels of the steps. A second rail, which is disposed on at least one of the upper white part and the lower part, and which is disposed above these along the second rail, and whose end near the longitudinal middle of the main frame is pivoted to a fixed body of the main frame. an actuating rail that is urged downward and normally held at a predetermined position facing the upper surface of the driven wheel; and an actuating rail that is attached to a fixed body of the main frame and presses against the driven wheel that is displaced upward. An escalator safety device equipped with a detection device that operates when the escalator is displaced.
