PROBLEM TO BE SOLVED: To provide fittings capable of enhancing the workability of erection and the replacement of a sash. SOLUTION: Since a notched portion 132G is formed in a jamb rail member 132 in a position out of any opening/closing moving areas of upper and lower movable sashes 20 and 30, a sliding shoe can be inserted through the inside and outside of the jamb rail member 132 via the notched portion 132G which is formed in a position to make operations relatively easy so as to enhance the workability of the erection and the replacement of each sash. In addition, the opening 132D and notched portion 132G of the jamb rail member 132 in an intermediate height position of a window frame are covered with a jamb cover so that the designing performance of appearance seen from an indoor side of a double-hung window 1 can also be enhanced.
