PROBLEM TO BE SOLVED: To prevent the situation where water infiltrates from a gap mutually between abutted stiles into the room, as further as possible.SOLUTION: A fixture comprises: an opening frame 10 which is disposed so as to attach/detach a rail part 14 to/from a lower frame 12; and a plurality of sashes 20 which are disposed so as to slide through the rail part 14 to the opening frame 10 in such a state where stiles 23 are abutted to each other when the opening frame 10 is closed. A plurality of rail parts 14 are disposed along a length direction of the lower frame 12 in the state where a position dislocated in the length direction from an abutting position 20A of the sashes 20 in the state where the opening frame 10 is closed, becomes a dividing surface 14A. Between the rail part 14 and the lower frame 12, a cut-off material 30 is disposed over a full length at least from the dividing surface 14A to a portion exceeding the abutting position 20A of the sashes 20. |
