In addition, when one sheet cannot be scratched, two sheets can be scratched.

  In addition, since a plurality of sheets are stacked, even if one sheet is worn due to cleaning, the second and subsequent sheets can be used for cleaning.

  In addition, since the elastic body that pushes down the sheet is provided, even if the sheet is worn and a gap is generated between the sheet and the step, the gap is filled and cleaning can be performed appropriately.

  Further, since a weight is provided to push the seat downward, even if the seat is worn and a gap is created between the seat and the step, the gap is filled and cleaning can be performed appropriately.

  Also, since the seat is angled so that the oil that is the object to be cleaned is pumped out to the inside of the skirt, it becomes difficult for the oil to be sent out to the center of the step, and the object to be cleaned accumulates in the center of the step and the passenger It is possible to prevent a situation that would cause a fall.

  It is also attached to the inner wall surface of the skirt near the entrance. Here, oil adheres to a step from a step chain or the like. For this reason, if oil is pumped out only inside the skirt, the oil may ooze out from the entrance to the exit and cause the passenger to fall. is there. However, by providing a step cleaning body at the entrance, oil can be dropped to the inside of the skirt at the timing when the step is exposed to the outside from the truss structure, further preventing the passenger from falling. can do.

  In addition, it is attached to the inner wall surface of the skirt near the exit, and an angle is provided in the vicinity of the exit to sweep out the oil that is the object to be cleaned to the step side. When the door and the entrance are switched, the step cleaning body pumps out oil to the inside of the skirt portion at the replaced entrance. Therefore, even when the entrance and the exit are reversed, it is possible to further prevent a situation that causes the passenger to fall.

  In addition, the angle of the seat changes so that the oil that is the object to be cleaned is pumped out to the inside of the skirt as the step direction changes, making it difficult for the oil to be sent out to the center of the step. Therefore, it is possible to prevent a situation in which cleaning objects accumulate and cause a passenger to fall. Furthermore, even when the entrance and the exit are reversed, it is difficult for the oil to be sent out to the center of the step, thereby further preventing a situation where the passenger falls.
