For this reason, it is possible to provide the resin-made fitting 1 excellent in assemblability and maintainability.

  Moreover, since the engagement metal fitting 30 is attached to the vertical rods 21c and 21d, even if it is exposed to a flame, the frame 21 is softened, and the pressing edge 6 fitted to the vertical rods 21c and 21d is also softened. However, the pressing edge 6 does not come off, and the end of the glass 50 in the direction of finding is held along the vertical direction. For this reason, for example, the glass 50 is suspended only by being held only on the upper flange 21a side, or the glass 50 is not supported only by the lower end while being held only by the lower flange 21b side. Even if the pressing edge 6 is softened, it is possible to provide the resin fitting 1 in which the glass 50 is more difficult to come off.

  Further, when the resin fitting 1 is exposed to a flame, the upper side of the resin fitting 1 is likely to be hotter, so the engagement fitting 30 is attached to the upper side of the vertical rods 21c and 21d. Then, it is possible to effectively prevent the pressing edge 6 from coming off on the upper side where the temperature tends to be high.

  Further, since the glass 50 is sandwiched between the side wall portion 35b of the fixing bracket 35 and the opposing plate portion 30b of the engagement bracket 30, not only does the pressing edge 6 come off even if the pressing edge 6 is softened by the heat of the flame, but also the glass. It is also possible to prevent 50 from coming off.

  In the said embodiment, although the engaging metal fitting 30 was set as the structure which has the opposing board part 30b which opposes the glass 50, the opposing board part 30b does not necessarily need to be provided. Moreover, although the pressing edge engaging part 30c inserted in the hollow part 6e of the pressing edge 6 contact | abutted with the inner wall 6g of the hollow part 6e, and the pressing edge 6 was urged | biased by the glass 50 side by elastic force, The engaging part 30c does not necessarily have to contact the inner wall 6g of the hollow part 6e, and the pressing edge 6 does not have to be urged toward the glass 50 by the elastic force. For example, in a state where the ledge 6 is attached, the ledge engaging portion 30c is inserted into the hollow portion 6e, and the ledge engaging portion 30c may be configured to support the ledge 6 when softened by a flame. Absent.

  In the above embodiment, the resin fitting 1 for sliding is described as an example. However, the present invention is not limited to this, and the opening is closed by attaching a sliding window such as an open window, a pulling window, and a raising / lowering window. It may be a resin fitting provided with a ledge for pressing a face material such as a fitting window.
