Between the sash facing surface portion 22a and the attachment facing surface portion 32a, an outdoor side seal member (first watertight portion) 56x and an indoor side seal member (second watertight portion) 57x are provided (see FIG. 2). The indoor side seal member 57x is provided at a position on the indoor side in a more watertight manner than the outdoor side seal member 56x.

  Similarly to the indoor side seal member 52x, the indoor side seal member 57x suppresses the passage of rainwater and the entry and exit of air between the outdoor side and the indoor side of the indoor side seal member 57x. Similar to the outdoor side seal member 51x, the outdoor side seal member 56x allows air to enter and exit while suppressing the passage of rainwater between the outdoor side and the indoor side of the outdoor side seal member 56x to some extent. Thereby, the outdoor side and the indoor side of the outdoor side sealing member 56x can be made equal pressure. In this way, by providing the outdoor side seal member 56x at the outdoor side position of the indoor side seal member 57x, in the same manner as when the outdoor side seal member 51x is provided, rainwater is prevented from being drawn into the indoor side.

  The sash facing surface portion 22 a of the attachment side frame 22 and the attachment facing surface portion 32 a of the sash side frame 32 are fastened to each other by screws 61.
