  In railways, a metal safety fence is installed about 20-30 cm away from the end of the platform to prevent passengers waiting for the train from falling on the platform. 2. Description of the Related Art In recent years, an automatic opening / closing type home door device (movable home fence) including a movable door portion that opens and closes outside a train door portion and a door pocket portion that houses the movable door portion has been installed. In such a conventional home door device, the wall-like movable door portion and the wall-like door pocket portion do not allow the body to be brought out to the track side, and the movable door portion is interlocked simultaneously with opening and closing of the train door. It is opened and closed to ensure passenger safety. In the conventional platform door device, the safety of passengers is improved by adopting glass for the movable door so that passengers on the platform can check the safety of their feet before boarding and can ride safely.

  In the conventional home door apparatus, since dirt accumulates on the glass surface of the movable door after about six months, it is necessary to periodically clean the glass surface. In the conventional platform door device, the glass surface on the platform side of the movable door can be easily cleaned because an operator can enter. However, in the conventional platform door device, although the glass surface on the track side of the movable door is within the construction limit, it is difficult for an operator to enter and perform the cleaning work. Here, the building limit is a space secured on a track where a building or the like should not enter in order for the railway vehicle to travel safely. For this reason, in the conventional platform door device, when cleaning the glass surface on the track side of the movable door, it is performed between trains so as not to interfere with the operation of the train, or the section to be cleaned is subject to operation handling After systematically closing the track to be released, workers need to enter the building limits. In addition, in the conventional platform door device, the glass surface on the track side of the movable door is cleaned from the platform side only within the reach of the worker's hand without the worker entering the building limit. The surface cannot be cleaned sufficiently. For this reason, in the conventional platform door device, even if the glass surface on the platform side of the movable door is cleaned, the cleaning of the glass surface on the track side of the movable door is insufficient, so the cleaning effect cannot be visually confirmed. .

  In the prior art 1, a worker on the ground moves the ridge connected to the pedestal on the cleaning surface of the house roof to move the pedestal, and water is sprayed from the nozzles of the injection pipes on the pedestal to house the roof. The cleaning surface is cleaned. However, in the prior art 1, when applied to the cleaning of the glass surface on the track side of the movable door of the platform door device, it is necessary for the worker to enter the building limit, and if the track is not closed, the cleaning work is performed. There are problems that cannot be implemented. In Prior Art 2, a rail is arranged outside the viewing window of the aquarium, the frame is moved along the rail, and the outside of the viewing window is cleaned with a rotating brush. However, in the prior art 2, when applied to cleaning the glass surface on the track side of the movable door of the platform door device, it is necessary to arrange a rail on the outside of the platform door device, and an extremely narrow space outside the platform door device. There are problems that it is difficult to arrange the rails on the rails and that the equipment becomes large and the cost becomes high.
