Claims

[Scope of utility model registration request]

A large number of steps are continuously connected to a step chain provided in an endless manner on the main frame, and the steps have an upper white part at the upper part of the main frame and a lower part at the lower part, and are operated in circulation along a predetermined route; a straight rail that is longitudinally arranged and fixed to the main frame and guides the lower surface of the roller of the step chain along the straight portion of the route; a first curved rail that guides the lower surface of the roller along the lower portion of the route;
A second curved rail that guides the lower surface of the roller along the upper white part of the route, and a third curved rail that guides the upper surface of the roller along the lower part of the route and has the same curvature as the second curved rail.
An escalator step device equipped with curved rails.
