Claims

[Scope of utility model registration request]

In an escalator in which a large number of steps are arranged on an endless step chain wrapped around sprockets at the upper and lower terminal sections, and guide rails for the front and rear wheels of the steps are provided, the upper terminal section Reduce the number of teeth and diameter of the sprocket and the radius of the upper semicircular terminal rail of the rear wheel guide rail to the extent that each step does not interfere with the front and rear, and reduce the number of teeth of the sprocket on the lower terminal. and the diameter of the lower floor semicircular terminal rail of the rear wheel guide rail is reduced to be slightly larger than that of the upper floor, and An escalator characterized in that the upward eccentricity of the arc center of the side terminal rail from the axis of the sprocket on the lower floor side is smaller than that on the upper floor side.
