The step 23 c has a height equivalent to the thickness of the inner wall that forms the communication flow path portion 29 a of the drainage bypass member 29. Thereby, the upper surface 22a of the indoor recess 22 and the communication flow path portion 29a of the drain bypass member 29 can be configured as a continuous flow path, and drainage can be performed smoothly. Further, the step 23c may be formed to have a height larger than the thickness of the inner wall that forms the communication flow path portion 29a. In this case, since the communication flow path portion 29a is lower than the upper surface 22a of the indoor recess 22, smooth drainage can be similarly performed.

  The drainage bypass member 29 takes out the water flowing into the indoor concave portion 22 on the side where the inner shoji 2 is disposed by the communication flow path portion 29a to the outside of the inner rail 23 and drains it. Drainage is performed on the outdoor side from the inner rail 23 separating the outside, and smooth drainage can be performed while preventing rainwater and wind from blowing into the room.

  The drainage bypass member 29 drains the water from the indoor recess 22 to the outside of the outdoor rail 24, so that the outer rail 24 is formed with a bypass notch 24c through which the drainage bypass member 29 is inserted.
