The ridge member 18 that enters the groove 13 of the other palm 5d when the shoji is closed is attached to the groove 13 of one of the palm ribs 5d. Since the airtight members 15a and 15b for sealing the gap between the protrusion members 18 are attached to the groove portion 13, the force does not increase immediately before the shoji is closed, and the locking operation of the crescent lock 11 does not become hard. Can be improved, warping deformation in the gas palm 5d Flip can be ensured airtightness, rafter stiles 5d is the manufacturing cost can be reduced in the left and right common cross-sectional shape.

  That is, since the left and right palm rods 5d have a symmetrical cross-sectional shape having grooves 13 continuous in the vertical direction on the opposite surface, one type of cross-sectional shape (grip palm) is used as the left and right palm rods 5d. What is necessary is just to manufacture, and it can use as the other palm palm only by turning upside down the same shape material of one joint palm, and can reduce a manufacturing cost by sharing a member (profile).

  The rib member 18 is attached to the groove portion 13 of one of the palm ribs 5d, and the airtight material 15a for sealing the space between the side surface portion (side piece portion) of the rib member 18 to the groove portions 13 of the right and left palm rod 5d, 15b is attached to each other, so that when the inner shoji 3 is abutted and closed, the protrusion member 18 of one of the palms 5d enters the groove 13 of the other palm 5d, and the airtight material 15a of the groove 13 15b come into sliding contact with the side surface portion of the ridge member 18 to seal, and unlike the conventional airtight structure in which the airtight materials are abutted against each other and crushed and sealed, the inner impeller 3 is easily closed with a light force. In addition, the crescent lock 11 can be easily locked with a light force, and the operability can be improved.

  In addition, since the protrusion member 18 attached to the groove portion 13 of the one palmar rod 5d enters the groove portion 13 of the other palmar rod 5d and the airtight members 15a and 15b are in contact with the side surfaces of the rib member 18, the right and left Even if warp deformation such as a drum shape or a drum shape is generated in the gas palm 5d, airtightness can be ensured.

  Further, the lower end portion of the indoor side piece 14a that forms the groove 13 is cut out, and the airtight blocks 24a and 24b are provided in the cutout portions 23a and 23b so that the airtight blocks 24a and 24b are brought into contact with each other when the shoji is closed. Since the lower frame airtight member 21 is brought into sliding contact with the airtight blocks 24a and 24b, the airtightness can be improved. In this case, a structure is adopted in which the airtight blocks 24a and 24b are brought into contact with each other and crushed to ensure airtightness. However, the airtight blocks 24a and 24b are only partially provided at the lower end of the joint palm 5d. Therefore, it is not necessary to increase the force when closing the shoji.
