Specifically, the wire winding unit 15 rotates the rotating body 17 configured to be able to wind the other end side of the wire 11 and the rotating body 17 in a direction to wind the other end side of the wire 11. 11 is provided with a mainspring spring 18 that biases 11.

  The wire winding means 15 that maintains the tension of the wire 11 prevents the wire 11 from being loosened and caught on the car doors 23A and 23B and the landing doors 33A and 33B. Moreover, since the 3rd brush 13 is arrange | positioned in the threshold grooves 25a and 35a containing the lower part of door guide shoes 27B and 37B, a foreign material is difficult to dive under the door guide shoes 27B and 37B. Thereby, it can suppress that the foreign material is pinched | interposed between the door guide shoes 27B and 37B and the bottom part of the threshold grooves 25a and 35a, and the cage doors 23A and 23B and the landing doors 33A and 33B are locked.

  Further, with respect to the frontage direction, the portions of the sill grooves 25a and 35a that are located in the opening direction of the car doors 23A and 23B and the landing doors 33A and 33B from the opening direction ends of the car doors 23A and 23B and the landing doors 33A and 33B are The car doors 23A and 23B and the landing doors 33A and 33B are always pressed against the third brush 13 that extends from the lower part of the end in the opening direction to the other end of the wire 11. For this reason, at the site | parts of the said sill | groove groove | channels 25a and 35a, the sweeping-out of a foreign material is suppressed, and the discharge effect of the foreign material to the exterior of the car sill 25 and the landing sill 35 is further acquired.

  In the second embodiment, the third brush 13 is attached to a portion of the wire 11 that is half the length of the car sill 25 and the landing sill 35 from one end of the wire 11 toward the other end. However, the third brush 13 does not have to be attached to the portion of the wire 11 that extends to the other end side from the portion of the car doors 23A and 23B and the landing doors 33A and 33B at the lower end of the opening direction. . Even in this case, the foreign matter in the sill grooves 25a and 35a can be discharged to the outside of the car sill 25 and the landing sill 35 through the discharge holes 25b and 35b by opening and closing the car doors 23A and 23B and the landing doors 33A and 33B.

  If the third brush 13 is extended to some extent from the lower part of the opening direction end of the car doors 23A, 23B and the landing doors 33A, 33B, the car doors 23a, 23B and the landing doors 33A, 33B are fully closed. When the car doors 23A and 23B and the landing doors 33A and 33B are open, the foreign material car sill 25 and the landing sill by the third brush 13 are located at the part of the sill grooves 25a and 35a positioned in the opening direction from the lower end of the opening direction. The effect of discharging 35 to the outside is improved.

  Further, although the wire tensioning unit has been described as being the wire winding unit 15, the wire tensioning unit may use, for example, a coil spring that biases the other end side of the wire 11.

  In each embodiment, the sill groove cleaning device has been described as being attached to both the car doors 23A and 23B and the landing doors 33A and 33B. However, any one of the car doors 23A and 23B and the landing doors 33A and 33B may be used. The thing attached with respect to may be sufficient.
