Abstract

In an escalator having a plurality of steps connected to an endless chain and moved along an endless path, a rotation locus of step forward wheels at both end portions is shifted toward end portions of the escalator relative to a rotation locus of the chain. A forward wheel guide track for guiding forward wheels of the steps is arranged, at both end portions of the escalator, so that a straight distance between forward wheels of two adjacent steps, which distance tends to be shortened by the chain following an arc at both end portions, is extended. By such constructions, interference between adjacent steps hardly occurs even if the rotation diameter of the steps at each end portion of the escalator is made small. Therefore, the rotation diameter of the steps can be made smaller than a conventional one and the escalator thickness (depth) can be made small.
