PROBLEM TO BE SOLVED: To allow a user to ascend and descend irrespective of his/her use of a wheelchair, lay an energy saving type intelligent escalator in a curve shape, and operate it by flexibly corresponding to increase or decrease of the number of users to save energy. SOLUTION: Any user can ascend or descend by adjusting shape of steps matching with ordinary user and the wheelchair by changing a system in which a plurality of steps connected by a chain being a basic part of the escalator move in a following manner into an independent system in which respective steps can move singly. It is possible to lay the escalator having a curve form easily by installing a guide rail in a curve shape because respective steps move independently on the guide rail in this system. The minimum number of required steps corresponding to increase or decrease of the number of users are moved in cooperation by moving steps independently to realize large energy saving effect.
