As shown in FIG. 6, when the third polished portion 11c is scraped away, the applicator 12 receives the load from the elastic body 14 and maintains contact with the upper surface of the threshold. At this time, the coating material is replenished to the application body 12 . In this state, when the landing door 4 is opened and closed, the applicator 12 moves while being in contact with the top surface of the landing threshold 7 . As a result, the upper surface of the landing threshold 7 is covered with the coating material.

According to the first embodiment described above, the polishing body 11 polishes the landing threshold 7 by moving according to the opening and closing of the landing door 4 . Therefore, the landing threshold 7 can be automatically polished. As a result, it is possible to reduce the number of maintenance operations performed by workers. In addition, the trouble of replacing the landing threshold 7 can be saved. Therefore, the maintenance cost of the landing threshold 7 can be reduced.

Further, the polishing body 11 is provided on the doorstop side of the landing door 4 . Therefore, it is possible to polish the entire area of the landing threshold 7 that is noticeable to the user.

Further, the polishing body 11 has a plurality of polishing portions arranged so that the mesh becomes finer toward the upper side. Therefore, the landing threshold 7 can be gradually polished.

Further, the applicator 12 applies the coating material to the landing threshold 7 by moving according to the opening and closing of the landing door 4 . Therefore, the coating material can be automatically applied to the landing threshold 7 .

Also, the coating material is replenished from the reservoir 15 . Therefore, shortage of the coating material can be suppressed.

Note that the polishing body 11 and the application body 12 may be provided separately. At this time, it may be set such that after polishing the landing threshold 7 with the polishing body 11 , the coating material is applied to the landing threshold 7 with the applicator 12 .
