It will be in the state which covered the part which provided material 15C. Moreover, the pressing edge 16 is supported only by the inner frame element 15B, and is not in contact with the outer frame element 15A. Accordingly, when the joinery is used in a normal state, heat transfer between the outer frame element 15A and the inner frame element 15B is suppressed, and for example, dew condensation is generated on the inner frame element 15B and the lid member 15D. There are advantages such as not occurring.

  On the other hand, even when a fire occurs outdoors, since the heat insulating material 15C is covered with the extended cover portion 16d of the pressing edge 16 in the face material accommodating portion 15E, for example, the window tight material AT1 is melted and the gap Even if a flame enters, the flame does not reach the heat insulating material 15C directly. Therefore, it is possible to prevent the heat insulating material 15C from being melted even in the event of a fire, and there is no possibility that the flame between the two frame elements 15A and 15B becomes a through-hole, and it is possible to prevent the spread of fire. In addition, since the extension cover portion 16d only needs to extend from the pressing edge 16 to the face material accommodating portion 15E, the heat insulating material 15C is surely secured even when the position for supporting the glass panel 30 or the expected size of the glass panel 30 is changed. It is possible to cover.

  In the above-described embodiment, only the vertical frame 15 of the frame 10 has been described. However, the same configuration may be applied to the upper frame 11 and the left and right vertical frames 13 and 14. Moreover, if it is a fitting provided with an invisible frame, it is also possible to apply to an invisible frame. Further, the face material sandwiched between the support fin 15Ac and the pressing edge 16 does not necessarily need to be a multi-layer glass panel 30, and is also applicable to a single glass panel or other face material sandwiched. Is possible.

  In the above-described embodiment, since the frame member is configured such that the inner frame element 15B having the pressing edge mounting portion 15Bd is on the indoor side, there is no possibility that the pressing edge 16 is removed from the outdoor side. In the present invention, the frame member may be configured such that the inner frame element is on the outdoor side.
