PROBLEM TO BE SOLVED: To implement a structure of a sash window frame device for repair, which can sufficiently bear a force applied to a new sill 6b when a sliding sash is pulled to the outside, without increasing a thickness of each component member of the device. SOLUTION: According to the structure, an upper portion of an indoor-side lower guide rail 11 protruded on an upper surface of an existing sill 2b is engaged with a hanging wall portion 31 hanging from a lower surface of a lower attachment 17, and therefore the lower attachment 17 functions to prevent the existing sill 2b from being displaced to the outside. Further the newly arranged sill 6b is firmly secured to the lower attachment 17 by means of second and third lower tapping screws 39, 40. COPYRIGHT: (C)2007,JPO&INPIT
