In the state, the frame 10 and the shojis 20a and 20b do not interfere with each other. For this reason, it is possible to open and close the shojis 20a and 20b smoothly.

  Moreover, since the shoji side movement restricting member 52 has the restricting plate portion 52e facing the frame side move restricting member 51 on the outdoor side of the frame side move restricting member 51, the lower ends of the shojis 20a and 20b are on the indoor side. Even if a tilt occurs in the out-of-plane direction so as to swing, the restricting plate portion 52e of the shoji-side member contacts the frame-side movement restricting member 51, and the tilt of the shoji 20a, 20b in the out-of-plane direction is also suppressed. Is possible.

  Further, an engaging member 42 that can be engaged with the frame 10 in a state in which the shoji 20a and 20b are closed is provided on the upper part of the shoji 20a and 20b, and the engaging member 42 is engaged on the upper part of the frame 10. The engaged member 41 to be engaged is provided, and when the shoji 20a, 20b and the frame 10 are exposed to the flame and softened or disappeared, the engaged member 41 and the engaging member 42 are engaged. Since the engaging piece 42b is supported on the bottom 41b of the engaged member 41 and the shojis 20a and 20b are suspended, it is possible to prevent the shojis 20a and 20b from falling off the frame 10.

  Further, in the resin fitting 1 of the present embodiment, the lower edge 42d of the engaging piece 42b of the engaging member 42 and the engaged member 41 are in a state where the shojis 20a and 20b are supported by the rail 8 via the door wheel 5. The vertical distance between the bottom 41b and the bottom 41b is equal to the vertical distance between the lower surface of the lower plate part 52c of the shoji side movement restricting member 52 and the upper end 51c of the standing wall part 51a of the frame side movement restricting member 51. When the joinery 1 is exposed to a flame and is softened or partially lost, the engaged member 41 and the engaging member 42 are engaged to suspend the shojis 20a and 20b, and the shoji side movement restricting member 52 is engaged. Is supported by the frame side movement restricting member 51, it is possible to more effectively prevent the shojis 20a and 20b from being inclined.

  In the above embodiment, the shoji side movement restricting member 52 is the restricting plate portion 52e facing the frame side movement restricting member 51 inserted into the groove portion 20c of the lower collar 21b and the indoor side protruding portion 12 or the outdoor side protruding portion 13.
