FIGS. 4 and 5 are views corresponding to FIGS. 1 and 2, respectively, and are a longitudinal sectional view and a transverse sectional view of the new window for refurbishment 1 when the new window for refurbishment 1 is a fixed window. When the new window 1 for refurbishment is a fixed window, the following additional effects occur.

  When the new window 1 for refurbishment is a fixed window, the new shoji 40 cannot be opened and closed, so that the configuration in which the inner frame 20 is slidable with respect to the outer frame 12 works more usefully. That is, when the new shoji 40 can be opened and closed, even if the inner frame 20 is not slidable with respect to the outer frame 12, a screw 80 for fixing the new window 1 for remodeling to the existing window frame 70 is provided. An appropriate space for stopping can be secured by the opening and closing. However, in the fixed window in which the new shoji 40 cannot be opened and closed, if the inner frame 20 is not slidable with respect to the outer frame 12, the screw 80 for fixing the refurbished new window 1 to the existing window frame 70 is stopped. It becomes difficult to secure an appropriate space. Therefore, when the new window for refurbishment 1 is a fixed window, the new window for refurbishment 1 is fixed to the existing window frame 70 by a configuration in which the inner frame 20 is slidable in the expected direction with respect to the outer frame 12. Therefore, an effect of creating an appropriate space for stopping the screw 80 is obtained.

  Moreover, in the said embodiment, although the window made from aluminum was mentioned as an example as the new window 1 for refurbishment, it is not limited to this, A resin-made window may be sufficient. Further, when the existing window frame 70 is made of aluminum and the new refurbishment window 1 is a resin window, the existing window made of metal can be refurbished to a new resin window, so that the heat insulating performance of the window is achieved. Can be increased.
