(8) is automatically stopped once in the state shown in FIG. This allows the lower wheelchair steps (8) to be manually operated by the attendant.
The operation of extending the extension tread (10) from the movable tread (9) can be easily performed.

When the wheelchair-equipped escalator is driven to descend by wheelchair driving, the upper wheelchair step (4) and the intermediate wheelchair step at the entrance at the end of the main frame (1).
(6) and the lower wheelchair step (8) move in a downward direction at a low speed, and the normal step (3) adjacent to the lower end of the main frame (1) of the lower wheelchair step (8) moves from horizontal movement to skew. And temporarily stops in a state in which it is lowered from the horizontal movement position. In this state, the extension tread (10) is extended from the movable tread (9) of the lower wheelchair step (8) by the manual operation of the attendant in the same manner as shown in FIG.

When the wheelchair user operates the escalator with a wheelchair step at a low speed in the early stage of the skewing movement, the condition of the wheelchair becomes unstable and a danger is expected. When you release your hand from step 17), the escalator with steps for wheelchairs stops. Accordingly, if the wheelchair mounting space formed for the wheelchair dimensions is insufficient, that is, depending on accessories mounted on the wheelchair, luggage loaded on the wheelchair, etc., for each wheelchair user different wheelchair dimensions. Therefore, it is possible to prevent an accident occurring during unstable transportation when the space for mounting a wheelchair is insufficient.

Also, when driving in the large wheelchair driving mode, the upper wheelchair step (4), the intermediate wheelchair step (6) and the lower wheelchair step (8) move at a low speed in the ascending direction, and the lower wheelchair step. (8) is temporarily stopped in the state shown in FIG.
