が多いという問題点があった。[Problems to be Solved by the Invention] A conventional elevator sill device is configured as described above, and since the guide groove 6a formed in the sill 6 has a rectangular cross section, as shown in FIG. If a hard foreign object such as a small stone 11 having a size similar to the groove width of the guide groove 6a enters the guide groove 6a, it will be sandwiched between the side walls 6d of the guide groove 6a. And the guide groove
Small stones 11 and the like that are firmly sandwiched between both side walls 6d of 6a cannot be removed only by moving the guide piece 10 in the guide groove 6a by opening and closing the door 4 at the landing, and hinder the movement of the guide piece 10 to prevent the door 4 from moving. It may interfere with opening and closing. Further, as shown in FIG. 8, the dust drop hole 6c provided on the bottom 6b of the guide groove 6a has a width A of the normal guide groove 6a.
Since the width B is narrower than that of the pebbles, even if the pebbles 11 move, the pebbles 11 do not pass through the dust drop hole 6c, stay in the guide groove 6a, and are pushed by the guide piece 10 of the door 4 several times. There is a problem that the pebbles 11 and the like roll and change their directions while being moved, and are often pinched tightly between both side walls of the guide groove 6a.

易に除去することができる。In the elevator sill device according to this embodiment, the inclined surfaces 6d 2 are formed in the both side grooves 6d of the guide groove 6a so that the width dimension C of the bottom 6b is larger than the width dimension A of the side of the opening 6e of the guide groove 6a. Since it is formed, as shown in FIG. 3, when a hard foreign matter such as a small stone 11 having a size similar to the width dimension A of the side of the opening 6e of the guide groove 6a enters the guide groove 6a, the landing door 4 The guide piece 10 projecting downward from the lower end of the guide groove and inserted into the guide groove 6a moves along the longitudinal direction of the guide groove 6a as the door 4 opens and closes, so that the pebbles 11 that have entered the guide groove 6a. Is pushed by the moving guide piece 10 and falls to the bottom 6b of the guide groove 6a.
It does not get pinched between both side walls 6d of 6a. The width dimension D of the dust drop hole 6c provided on the bottom 6b of the guide groove 6a is determined by the guide groove 6a.
Since it is made larger than the width dimension A of the side of the opening 6e, the pebbles 11 and the like that fall on the bottom 6b as described above are
It falls from 6c to the lower side of the sill 6, and therefore the pebbles 11 and the like can be easily removed.
