The first upper frame part 41 and the second upper frame part 42 may be integrally formed. Even in this case, by providing the drainage attachment portion 63 for detachably attaching the upper drainage 64 to the upper frame 23, the upper drainage 64 can be detached from the upper frame 23 when the shutter device 71 is installed.

  (3) In the above embodiment, the end on the outdoor side of the drainage mounting portion 63 is set at the substantially same position as the outer wall surface 15a in the wall thickness direction, but this is changed to be positioned on the indoor side with respect to the outer wall surface 15a. May be. If it does so, since it can avoid that the shutter box 73 interferes with the drainage attachment part 63 at the time of installation of the shutter apparatus 71, the protrusion width | variety from the outer wall surface 15a of the shutter box 73 can be made still smaller.

  (4) In the above embodiment, the overlapping portion (opposed portion) of the rising portion 46 of the first upper frame portion 41 and the rising portion 55 of the second upper frame portion 42 is fixed to the outdoor side surface of the horizontal frame member 38 with screws or the like. May be. If it does so, the attachment state of the upper frame 23 can be made more stable. In this case, screws or the like are tightened from the outdoor side of the standing portion 55 to the standing portions 46 and 55 and the flange 38c of the horizontal frame member 38, respectively.

  (5) In the above embodiment, the opening frame structure of the present invention is applied to the sash frame 22 (corresponding to the opening frame) of the sash door 27 formed of a sliding window, but other types such as a sliding window and a fall-down window are used. You may apply this invention with respect to the sash frame of the sash door which consists of this window. Further, the present invention is not limited to the sash frame 22 of the openable / movable sash door 27 (corresponding to the joinery), and for example, the present invention is applied to an opening frame of a fitting window that is attached to the window portion 21 by fitting. Also good.

  Further, the opening frame structure of the present invention is not necessarily applied only to the window portion 21, but can also be applied to an opening portion (entrance / exit) such as a sweeping window that allows people to enter and exit. .
