The respective widths of the first sliding door 3 to the fourth sliding door 6 are the same. The first screen door 7 and the second screen door 8 have the same width corresponding to each one sliding door.

[0012] As shown in FIG. 1, the first sliding door 3 includes an upper frame 31 and a lower frame 32 each extending in the horizontal direction, a door-tip-side vertical frame 33 extending in the vertical direction on the door-tip side (the right side in FIG. 1), and a door-bottom-side vertical frame 34 extending in the vertical direction on the door-bottom side (the left side in FIG. 1). A face material 35 is accommodated inside a frame body 30 formed in a rectangular shape by the above. As shown in FIG. 3, the face material 35 is composed of three glass plates laminated with a spacer 351 interposed therebetween. The door-tip-side vertical frame 33 of the first sliding door 3 is the first door-tip-side vertical frame, and the door-bottom-side vertical frame 34 is the first door-bottom-side vertical frame.

[0013] The upper frame 31 of the first sliding door 3 has a composite structure in which a resin frame 312 is attached to the indoor side X2 of a metal frame 311 such as aluminum. The lower frame 32 of the first sliding door 3 has a composite structure in which a resin frame 322 is attached to the indoor side X2 of a metal frame 321 such as aluminum. A crescent lock 36 for locking and unlocking with respect to the third sliding door 5 is provided on the first door-bottom-side vertical frame 34.

[0014] As shown in Fig. 1, the second shoji 4 is arranged on the right side of the first shoji 3 when the furniture 1 in the closed state is viewed from the indoor side X2. The second shoji 4 includes a top frame 41 and a bottom frame 42 that each extend horizontally, a leading-side vertical frame 43 that extends vertically on the leading side (left side in Fig. 1), and a trailing-side vertical frame 44 that extends vertically on the trailing side (right side in Fig. 1). A facing material 45 is accommodated inside a frame body 40 that is framed in a rectangle by these components. Similar to the facing material 35 of the first shoji 3, the facing material 45 is also composed of three glass plates laminated with spacers in between. The leading-side vertical frame 43 in the second shoji 4 is the second leading-side vertical frame, and the trailing-side vertical frame 44 is the second trailing-side vertical frame.

[0015] Similar to the top frame 31 and the bottom frame 32 of the first shoji 3, the top frame 41 and the bottom frame 42 of the second shoji 4 each have a composite structure in which a resin frame is attached to the indoor side X2 of a metal frame body such as aluminum. A crescent lock 46 for locking and unlocking the fourth shoji 6 is provided on the trailing-side vertical frame 44.

[0016] As shown in Fig. 1, the third shoji 5 is arranged on the left side of the first shoji 3 when the furniture 1 in the closed state is viewed from the indoor side X2. The third shoji 5 includes a top frame 51 and a bottom frame 52 that each extend horizontally, a leading-side vertical frame 53 that extends vertically on the leading side (left side in Fig. 1), and a trailing-side vertical frame 54 that extends vertically on the trailing side (right side in Fig. 1). A facing material 55 is accommodated inside a frame body 50 that is framed in a rectangle by these components. Similar to the facing material 35 of the first shoji 3, the facing material 55 is also composed of three glass plates laminated with spacers in between. The leading-side vertical frame 53 in the third shoji 5 is the third leading-side vertical frame, and the trailing-side vertical frame 54 is the third trailing-side vertical frame.

[0017] Similar to the top frame 31 and the bottom frame 32 of the first shoji 3, the top frame 51 and the bottom frame 52 of the third shoji 5 each have a composite structure in which a resin frame is attached to the indoor side X2 of a metal frame body such as aluminum. An auxiliary locking mechanism 56 for locking the lower end of the trailing-side vertical frame 34 of the first shoji 3 is provided on the bottom frame 52 of the third shoji 5.

[0018] As shown in Fig. 1, the fourth shoji 6 is arranged on the right side of the second shoji 4 when the furniture 1 in the closed state is viewed from the indoor side X2. The fourth shoji 6 includes a top frame 61 and a bottom frame 62 that each extend horizontally, a leading-edge side vertical frame 63 that extends vertically on the leading-edge side (the right side in Fig. 1), and a trailing-edge side vertical frame 64 that extends vertically on the trailing-edge side (the left side in Fig. 1). A face material 65 is accommodated inside a frame body 60 that is rectangularly framed by these components. Similar to the face material 35 of the first shoji 3, the face material 65 is also composed of three glass plates laminated with spacers in between. The leading-edge side vertical frame 63 of the fourth shoji 6 is the fourth leading-edge side vertical frame, and the trailing-edge side vertical frame 64 is the fourth trailing-edge side vertical frame.

[0019] The top frame 61 and the bottom frame 62 of the fourth shoji 6 each have a composite structure in which a resin frame is attached to the indoor side X2 of a metal frame body such as aluminum, similar to the top frame 31 and the bottom frame 32 of the first shoji 3. An auxiliary locking mechanism 66 is provided on the bottom frame 62 of the fourth shoji 6 to lock against the lower end of the trailing-edge side vertical frame 44 of the second shoji 4.

[0020] As shown in Fig. 1, when the furniture 1 is in the closed state, the leading-edge side vertical frame 33 of the first shoji 3 and the leading-edge side vertical frame 43 of the second shoji 4 butt against each other at the center in the left-right direction of the frame body 2. As a result, a butting portion 10 is formed on the leading-edge side of each of the first shoji 3 and the second shoji 4. The trailing-edge side vertical frame 54 of the third shoji 5 is arranged to overlap the outdoor side X1 of the trailing-edge side vertical frame 34 of the first shoji 3. As a result, a summoning portion 11 is formed on the trailing-edge side of the first shoji 3 and the trailing-edge side of the third shoji 5. The trailing-edge side vertical frame 64 of the fourth shoji 6 is arranged to overlap the outdoor side X1 of the trailing-edge side vertical frame 44 of the second shoji 4. As a result, a summoning portion 12 is formed on the trailing-edge side of the second shoji 4 and the trailing-edge side of the fourth shoji 6.

[0021] When the fitting 1 is viewed from the indoor side X2, as shown in FIG. 2, the overall width W1 of the butting portion 10 in a state where the door-end side vertical frame 33 of the first shoji 3 and the door-end side vertical frame 43 of the second shoji 4 are butted together, the width W2 of the calling portion 11 composed of the door-bottom side vertical frame 34 of the first shoji 3 and the door-bottom side vertical frame 54 of the third shoji 5, and the width W3 of the calling portion 12 composed of the door-bottom side vertical frame 44 of the second shoji 4 and the door-bottom side vertical frame 64 of the fourth shoji 6 are equal. Therefore, when the entire fitting 1 is observed, the butting portion 10 and the calling portions 11 and 12 are visually recognized to have the same width, resulting in excellent design quality. The term "equal" is not limited to the case where the widths W1, W2, and W3 completely match, but means that manufacturing errors of the vertical frames 33, 34, 43, and 44 may be included to the extent that they are recognized as having the same width when the fitting 1 is viewed from the indoor side X2.

[0022] Next, the configuration of the butting portion 10 will be described with reference to FIG. 4. The butting portion 10 is configured by butting the door-end side vertical frame 33 of the first shoji 3 and the door-end side vertical frame 43 of the second shoji 4 from the left-right direction when the first shoji 3 and the second shoji 4 are closed. The door-end side vertical frames 33 and 43 do not have a shape in which one vertical frame covers and engulfs the indoor-side finding surface of the other vertical frame.

[0023] The door-end side vertical frame 33 of the first shoji 3 has a metal door-end side vertical frame main body 331, an indoor-side protruding portion 332 provided on the indoor side X2 of the door-end side vertical frame main body 331, and an outdoor-side protruding portion 333 provided on the outdoor side X1 of the door-end side vertical frame main body 331.

[0024] The door-end side vertical frame main body 331 is formed in a plate shape extending in the prospective direction and the vertical direction so as to cover the prospective surface of the grating channel 352 on the door-end side of the facing material 35. An outdoor-side protruding piece 3311 extending in the finding direction toward the second shoji 4 is integrally provided at the end of the outdoor side X1 of the door-end side vertical frame main body 331. An outdoor-side fin member 3312 having elasticity is attached to the indoor-side X2 surface of the outdoor-side protruding piece 3311.

[0025] The indoor-side protrusion 332 protrudes toward the indoor side X2 from the facing material 35. The indoor-side protrusion 332 is composed of a metal protrusion main body 3321 and a resin cover 3322 that covers the outside of the protrusion main body 3321.

[0026] The protrusion main body 3321 is integrally formed with the door-tip side vertical frame main body 331. The protrusion main body 3321 is formed in a rectangular shape that is long in the prospective direction and has a hollow portion 3321a inside. The protrusion main body 3321 protrudes toward the facing material 35 side from the door-tip side vertical frame main body 331 and is arranged so as to overlap the indoor side X2 of the spacer 351.

[0027] The resin cover 3322 is attached to cover the entire outer surface of the protrusion main body 3321 at intervals via a plurality of ribs 3322d. The resin cover 3322 has an inner prospective wall portion 3322a and an outer prospective wall portion 3322b arranged to cover the left and right prospective surfaces of the protrusion main body 3321, and an indoor-side finding wall portion 3322c arranged to cover the indoor-side finding surface of the protrusion main body 3321. The inner prospective wall portion 3322a and the outer prospective wall portion 3322b are arranged parallel to each other and extend in the prospective direction. The resin cover 3322 is attached to the outer surface of the protrusion main body 3321 via a plurality of ribs 3322d, so that a plurality of hollow portions 3322e partitioned by the ribs 3322d are formed between the outer surface of the protrusion main body 3321 and the inner surface of the resin cover 3322.

[0028] The position in the prospective direction of the end portion on the outdoor side X1 of the outer prospective wall portion 3322b substantially coincides with the position of the surface on the indoor side X2 of the facing material 35. An indoor-side protruding piece 3323 that extends in the finding direction toward the second shoji 4 is integrally provided at the end portion on the outdoor side X1 of the outer prospective wall portion 3322b. The protruding amount of the indoor-side protruding piece 3323 in the finding direction is equal to the protruding amount of the outdoor-side protruding piece 3311 in the finding direction. An elastic indoor-side fin member 3324 is attached to the surface on the outdoor side X1 of the indoor-side protruding piece 3323.

[0029] The indoor finding wall portion 3322c has a width that can cover the spacer 351 of the door end vertical frame body 331 and the facing material 35 from the indoor side X2. Further, a plurality of hollow portions 3322e provided between the protruding portion main body 3321 and the resin cover 3322 are also arranged so as to cover the spacer 351 of the facing material 35 from the indoor side X2. As a result, since the door end vertical frame body 331 and the spacer 351 are difficult to be visually recognized from the indoor side X2, the design property and heat insulation property on the door end side of the first shoji 3 are improved. Since the resin cover 3322 partitions the plurality of hollow portions 3322e by the plurality of ribs 3322d, the strength of the resin cover 3322 is improved, and there is no possibility of bending when the resin cover 3322 is gripped.

[0030] The outdoor protruding portion 333 protrudes to the outdoor side X1 more than the outdoor rail 222. The position of the outdoor protruding portion 333 on the outermost outdoor side X1 is close to the moving regions of the first screen door 7 and the second screen door 8 that slide the screen door rail 223 left and right. The outdoor protruding portion 333 is made of metal and is integrally formed with the door end vertical frame body 331. The outdoor protruding portion 333 is formed in a rectangular shape that is long in the prospective direction and has a hollow portion 333a inside.

[0031] The outdoor protruding portion 333 has an inner prospective wall portion 3331 and an outer prospective wall portion 3332 that form the left and right prospective surfaces, and an outdoor finding wall portion 3333 that faces the outdoor side X1. The inner prospective wall portion 3331 and the outer prospective wall portion 3332 are arranged parallel to each other and extend toward the outdoor side X1. The width of the outdoor finding wall portion 3333 of the outdoor protruding portion 333 is equivalent to the width of the indoor finding wall portion 3322c that constitutes the indoor finding surface of the indoor protruding portion 332. The inner prospective wall portion 3331 and the outer prospective wall portion 3332 of the outdoor protruding portion 333 are arranged on substantially the same plane along the prospective direction as the inner prospective wall portion 3322a and the outer prospective wall portion 3322b of the resin cover 3322 in the indoor protruding portion 332.

[0032] As shown in FIG. 3, the upper end surface 333b of the outdoor protruding portion 333 is flush with the upper end surface 31a of the upper frame 31 of the first shoji 3, and is disposed above the lower end portion 212a of the outdoor rail 212 of the upper horizontal frame 21. An engaging groove 3334 for engaging with the outdoor rail 212 is formed at the upper end portion of the outdoor protruding portion 333. On the outdoor side X1 and the indoor side X2 of the engaging groove 3334 in the outdoor protruding portion 333, an outdoor extending portion 3334a and an indoor extending portion 3334b that extend above the lower end portion 212a of the outdoor rail 212 are respectively disposed. The upper end portion of the outdoor protruding portion 333 is engaged with the outdoor rail 212 so as to sandwich it from the outdoor side X1 and the indoor side X2 by the engaging groove 3334, the outdoor extending portion 3334a, and the indoor extending portion 3334b.

[0033] The lower end surface 333c of the outdoor protruding portion 333 is flush with the lower end surface 32a of the lower frame 32 of the first shoji 3, and is disposed above the upper end portion 222a of the outdoor rail 222 of the lower horizontal frame 22. An engaging groove 3335 for engaging with the outdoor rail 222 is formed at the lower end portion of the outdoor protruding portion 333. On the outdoor side X1 and the indoor side X2 of the engaging groove 3335 in the outdoor protruding portion 333, an outdoor extending portion 3335a and an indoor extending portion 3335b that extend below the upper end portion 222a of the outdoor rail 222 are respectively disposed. The lower end portion of the outdoor protruding portion 333 is engaged with the outdoor rail 222 so as to sandwich it from the outdoor side X1 and the indoor side X2 by the outdoor extending portion 3335a and the indoor extending portion 3335b.

[0034] In this way, when the outdoor protruding portion 333 engages with the outdoor rails 212 and 222 of the upper horizontal frame 21 and the lower horizontal frame 22, when the first shoji 3 is subjected to wind pressure and moves in the expected direction, the outdoor protruding portion 333 contacts the outdoor rails 212 and 222. Therefore, the wind pressure resistance performance of the first shoji 3 is enhanced.

[0035] The door tip side vertical frame 43 of the second shoji 4 includes a metal door tip side vertical frame main body 431, an indoor protruding portion 432 provided on the indoor side X2 of the door tip side vertical frame main body 431, and an outdoor protruding portion 433 provided on the outdoor side X1 of the door tip side vertical frame main body 431.

[0036] The leading - end vertical frame body 431 is formed in a plate shape extending in the prospective direction and the vertical direction so as to cover the prospective surface of the grating channel 452 on the leading - end side of the facing material 45. An outdoor - side projecting piece 4311 extending in the finding direction toward the first shoji 3 is integrally provided at the end of the outdoor - side X1 of the leading - end vertical frame body 431. In the closed state of the first shoji 3 and the second shoji 4, the outdoor - side projecting piece 4311 is arranged so as to overlap with the indoor - side X2 of the outdoor - side projecting piece 3311 of the first shoji 3. Thereby, the outdoor - side projecting piece 4311 contacts the outdoor - side fin member 3312 and forms an airtight portion on the outdoor - side X1 of the leading - end vertical frame body 431.

[0037] The indoor - side projecting portion 432 projects more toward the indoor - side X2 than the facing material 45 with the same projecting amount as the indoor - side projecting portion 332 of the first shoji 3. The indoor - side projecting portion 432 is composed of a metal projecting - portion main body 4321 and a resin cover 4322 covering the outside of the projecting - portion main body 4321.

[0038] The projecting - portion main body 4321 is integrally formed with the leading - end vertical frame body 431. The projecting - portion main body 4321 is formed in a rectangular shape long in the prospective direction and has a hollow portion 4321a inside. The projecting - portion main body 4321 projects more toward the facing - material 45 side than the leading - end vertical frame body 431 and is arranged so as to overlap with the indoor - side X2 of the spacer 451.

[0039] The resin cover 4322 is attached so as to cover the whole, with a space from the outer surface of the protruding part main body 4321 via a plurality of ribs 4322d. The resin cover 4322 has an inner prospective wall part 4322a and an outer prospective wall part 4322b arranged so as to cover the left and right prospective surfaces of the protruding part main body 4321, and an indoor finding wall part 4322c arranged so as to cover the indoor finding surface of the protruding part main body 4321. The inner prospective wall part 4322a and the outer prospective wall part 4322b are arranged parallel to each other and extend in the prospective direction. By attaching the resin cover 4322 to the outer surface of the protruding part main body 4321 via a plurality of ribs 4322d, a plurality of hollow parts 4322e partitioned by the ribs 4322d are formed between the outer surface of the protruding part main body 4321 and the inner surface of the resin cover 4322.

[0040] The position in the prospective direction of the end part on the outdoor side X1 of the outer prospective wall part 4322b substantially coincides with the position of the surface on the indoor side X2 of the facing material 45. An indoor-side protruding piece 4323 extending in the finding direction toward the first shoji 3 is integrally provided at the end part on the outdoor side X1 of the outer prospective wall part 4322b. The protruding amount in the finding direction of the indoor-side protruding piece 4323 is equal to the protruding amount in the finding direction of the outdoor-side protruding piece 4311. In the closed state of the first shoji 3 and the second shoji 4, the indoor-side protruding piece 4323 is arranged so as to overlap with the outdoor side X1 of the indoor-side protruding piece 3323 of the first shoji 3. Thereby, the indoor-side protruding piece 4323 contacts the outdoor-side fin member 3324 and forms an airtight part on the indoor side X2 in the door-end side vertical frame main body 431.

[0041] The indoor-side finding wall portion 4322c has a width capable of covering the spacer 451 of the door-end side vertical frame body 431 and the facing material 45 from the indoor side X2. Further, a plurality of hollow portions 4322e provided between the protruding portion main body 4321 and the resin cover 4322 are also arranged so as to cover the spacer 451 of the facing material 45 from the indoor side X2. Thereby, since the door-end side vertical frame body 431 and the spacer 451 are difficult to be visually recognized from the indoor side X2, the design property and heat insulation property on the door-end side of the second shoji 4 are improved. Since the resin cover 4322 partitions the plurality of hollow portions 4322e by the plurality of ribs 4322d, the strength of the resin cover 4322 is improved, and there is no possibility of bending when the resin cover 4322 is gripped.

[0042] The outdoor-side protruding portion 433 protrudes outward from the outdoor side X1 more than the outdoor-side rail 222 by the same protruding amount as the outdoor-side protruding portion 433 of the first shoji 3. The outdoor-side protruding portion 433 is made of metal and is integrally formed with the door-end side vertical frame body 431. The outdoor-side protruding portion 433 is formed in a rectangular shape that is long in the prospective direction and has a hollow portion 433a inside.

[0043] The outdoor-side protruding portion 433 has an inner prospective wall portion 4331 and an outer prospective wall portion 4332 that form the left and right prospective surfaces, and an outdoor-side finding wall portion 4333 that faces the outdoor side X1. The inner prospective wall portion 4331 and the outer prospective wall portion 4332 are arranged parallel to each other and extend toward the outdoor side X1. The width of the outdoor-side finding wall portion 4333 of the outdoor-side protruding portion 433 is equivalent to the width of the indoor-side finding wall portion 4322c that constitutes the indoor-side finding surface of the indoor-side protruding portion 432. The inner prospective wall portion 4331 and the outer prospective wall portion 4332 of the outdoor-side protruding portion 433 are arranged on substantially the same plane along the prospective direction as the inner prospective wall portion 4322a and the outer prospective wall portion 4322b of the resin cover 4322 in the indoor-side protruding portion 433.

[0044] Although not shown, similar to the outdoor protruding portions 333 of the first shoji 3 shown in FIG. 3, engaging grooves that engage with the outdoor rails 212 and 222 of the upper horizontal frame 21 and the lower horizontal frame 22, and outdoor extension portions and indoor extension portions disposed on the outdoor side X1 and the indoor side X2 of the engaging grooves are provided at the upper and lower ends of the outdoor protruding portion 433 of the second shoji 4. The outdoor protruding portion 433 is engaged with the outdoor rails 212 and 222 of the upper horizontal frame 21 and the lower horizontal frame 22. Therefore, when the second shoji 4 also moves in the expected direction under wind pressure, the outdoor protruding portion 433 contacts the outdoor rails 212 and 222, and the wind pressure resistance performance is enhanced.

[0045] The lateral width W1 of the butting portion 10 is the total lateral width of the two indoor protruding portions 332 and 432 and the total lateral width of the two outdoor protruding portions 333 and 433, and is the same on the outdoor side X1 and the indoor side X2. The lateral width W1 of the butting portion 10 is the separation distance between the inner expected wall portion 3322a of the indoor protruding portion 332 of the first shoji 3 and the inner expected wall portion 4322a of the indoor protruding portion 432 of the second shoji 4, and is the separation distance between the inner expected wall portion 3331 of the outdoor protruding portion 333 of the first shoji 3 and the inner expected wall portion 4331 of the outdoor protruding portion 433 of the second shoji 4.

[0046] The lateral width W1a of the door tip side vertical frame 33 of the first shoji 3 and the lateral width W1b of the door tip side vertical frame 43 of the second shoji 4 in the butting portion 10 are set to be 1 / 2 or less of the lateral width W2 of the door butt side vertical frame 34 of the first shoji 3 that constitutes the calling portion 11 shown in FIG. 2 and the lateral width W3 of the door butt side vertical frame 44 of the second shoji 4 that constitutes the calling portion 12, respectively. It is not necessary to form the door tip side vertical frames 33 and 43 such that one vertical frame covers and engulfs the indoor finding surface of the other vertical frame, and the total lateral width W1 of the butting portion 10 can be easily unified with the lateral widths W2 and W3 of the calling portions 11 and 12. Although the lateral widths W1a and W1b in the present embodiment are formed to be the same, the lateral widths W1a and W1b do not necessarily have to be the same.

[0047] The widths W1a and W1b of the leading-edge vertical frames 33 and 43 on the door side of this embodiment are smaller than half of the widths W2 and W3 of the calling parts 11 and 12. Therefore, in the closed state of the first sliding door 3 and the second sliding door 4, gaps S are formed on the outdoor side X1 and the indoor side X2, respectively, between the leading-edge vertical frame 33 of the first sliding door 3 and the leading-edge vertical frame 43 of the second sliding door 4. This gap S can be used as a space for gripping when inserting a finger during the opening and closing operation of the first sliding door 3 and the second sliding door 4, and the operability of the first sliding door 3 and the second sliding door 4 is improved. By forming the gap S between the leading-edge vertical frames 33 and 43, there is no risk of pinching a finger between the leading-edge vertical frames 33 and 43 when closing the first sliding door 3 and the second sliding door 4.

[0048] Next, the configuration of the calling part 11 will be described with reference to FIG. 5. The calling part 11 is configured by overlapping the trailing-edge vertical frame 34 of the first sliding door 3 and the trailing-edge vertical frame 54 of the third sliding door 5 in the prospective direction when the first sliding door 3 and the third sliding door 5 are closed.

[0049] The trailing-edge vertical frame 34 of the first sliding door 3 is composed of a metal trailing-edge vertical frame body 341 and a resin cover 342 provided to cover the outer surface of the trailing-edge vertical frame body 341.

[0050] The trailing-edge vertical frame body 341 covers the prospective surface of the grating channel 352 on the trailing-edge side of the facing material 35 and is provided so as to protrude more toward the indoor side X2 than the facing material 35. Inside the trailing-edge vertical frame body 341, a rectangular first hollow portion 341a and a second hollow portion 341b are provided, respectively. The first hollow portion 341a is arranged to cover the prospective surface of the grating channel 352. The second hollow portion 341b is arranged on the indoor side X2 of the first hollow portion 341a and protrudes more toward the indoor side X2 than the facing material 35 of the first sliding door 3. A partition wall 341c extending in the prospective direction is formed between the first hollow portion 341a and the second hollow portion 341b.

[0051] In the door-end side vertical frame body 341, the outdoor-side prospective wall portion 341d disposed on the outdoor side X1 of the first hollow portion 341a and the indoor-side prospective wall portion 341e disposed on the indoor side X2 of the second hollow portion 341b are each formed to have a greater thickness in the prospective direction than the other wall portions extending in the prospective direction.

[0052] The end portion on the outdoor side X1 of the door-end side vertical frame body 341 protrudes to the outdoor side X1 with respect to the facing material 35. On the end portion on the outdoor side X1 of the door-end side vertical frame body 341, a support piece 3411 protrudes in the finding direction toward the door tip side (the right side in FIG. 5) from the first hollow portion 341a. The support piece 3411 is in contact with the grating channel 352 on the door-end side from the outdoor side X1.

[0053] On the outdoor side X1 of the support piece 3411 in the door-end side vertical frame body 341, a concave groove portion 3412 is formed. The concave groove portion 3412 is formed to be recessed from the door tip side (the right side in FIG. 5) toward the door-end side (the left side in FIG. 5) along the support piece 3411. The concave groove portion 3412 has a shape that is open toward the door tip side.

[0054] The resin cover 342 is attached so as to cover the prospective surface and the indoor-side finding surface of the door-end side vertical frame body 341. The resin cover 342 has an inner prospective wall portion 342a and an outer prospective wall portion 342b disposed so as to cover the left and right prospective surfaces of the door-end side vertical frame body 341, and an indoor-side finding wall portion 342c disposed so as to cover the indoor-side finding surface of the door-end side vertical frame body 341. The inner prospective wall portion 342a and the outer prospective wall portion 342b are disposed parallel to each other and extend in the prospective direction.

[0055] The end of the inner projected wall portion 342a on the outdoor side X1 abuts against the grating channel 352 on the door bottom side from the indoor side X2, sandwiching and supporting the facing material 35 between it and the support piece 3411. The outer projected wall portion 342b extends in the projected direction so as to cover the entire projected surface on the outside of the door bottom side vertical frame body 341. The indoor side finding wall portion 342c has a width that can cover the door bottom side vertical frame body 341 and the spacer 351 of the facing material 35 from the indoor side X2. Since the door bottom side vertical frame body 341 and the spacer 351 are difficult to be visually recognized from the indoor side X2, the design property and heat insulation property of the door bottom side of the first shoji 3 are improved.

[0056] The door bottom side vertical frame 54 of the third shoji 5 is composed of a metal door bottom side vertical frame body 541 and a resin cover 542.

[0057] The door bottom side vertical frame body 541 is provided so as to cover the projected surface of the grating channel 552 on the door bottom side in the facing material 55. A hollow portion 541a is provided inside the door bottom side vertical frame body 541.

[0058] At the end of the door bottom side vertical frame body 541 on the outdoor side X1, a support piece 5411 projects in the finding direction toward the door tip side (the left side in FIG. 5) from the hollow portion 541a. The support piece 5411 abuts against the grating channel 552 on the door bottom side from the outdoor side X1.

[0059] At the end of the door bottom side vertical frame body 541 on the indoor side X2, a projecting piece 5412 projecting toward the door tip side (the left side in FIG. 5) is formed. The projecting piece 5412 forms a labyrinth structure by being inserted into a concave groove portion 3412 provided on the outdoor side X1 of the door bottom side vertical frame 34 of the first shoji 3 in the closed state of the first shoji 3 and the third shoji 5.

[0060] At the end of the indoor side X2 of the door end vertical frame body 541, a fin member 5413 having elasticity and protruding toward the indoor side X2 is attached to the outside in the finding direction (the right side in FIG. 5) of the protruding piece 5412. In the closed state of the first shoji 3 and the third shoji 5, the fin member 5413 contacts the support piece 3411 of the door end vertical frame 34 of the first shoji 3 from the outdoor side X1, and forms an airtight part between the door end vertical frames 34 and 54.

[0061] The resin cover 542 is attached so as to protrude from the end of the indoor side X2 of the door end vertical frame body 541 toward the inner side in the prospective direction (the left side in FIG. 5). The resin cover 542 abuts on the grating channel 552 on the door end side of the third shoji 5 from the indoor side X2, and sandwiches and supports the facing material 55 between it and the support piece 5411. The resin cover 542 covers the spacer 551 of the facing material 55 from the indoor side X2. Since the spacer 351 is difficult to be seen from the indoor side X2, the design property and heat insulation property on the door end side of the third shoji 5 are improved.

[0062] The lateral width W2 of the calling part 11 when the fitting 1 is viewed from the indoor side X2 is the lateral width of the indoor side finding wall part 342c of the resin cover 342 on the door end vertical frame 34 of the first shoji 3. The lateral width of the door end vertical frame 54 of the third shoji 5 is equal to the lateral width of the indoor side finding wall part 342c of this resin cover 342. Therefore, when the fitting 1 is viewed from the indoor side X2 in the closed state of the first shoji 3 and the third shoji 5, the door end vertical frame 54 of the third shoji 5 is completely hidden and arranged on the outdoor side X1 of the door end vertical frame 34 of the first shoji 3.

[0063] Next, the configuration of the calling part 12 will be described with reference to FIG. 6. The calling part 12 is configured by overlapping the door end vertical frame 44 of the second shoji 4 and the door end vertical frame 64 of the fourth shoji 6 in the prospective direction when the second shoji 4 and the fourth shoji 6 are closed. The calling part 12 has a structure symmetrical to the left and right with respect to the calling part 11.

[0064] The vertical frame 44 on the door end side of the second shoji 4 is composed of a metal vertical frame body 441 on the door end side and a resin cover 442 provided to cover the outer surface of the vertical frame body 441 on the door end side.

[0065] The vertical frame body 441 on the door end side is provided so as to cover the prospective surface of the grating channel 452 on the door end side of the facing material 45 and to protrude toward the indoor side X2 with respect to the facing material 45. Inside the vertical frame body 441 on the door end side, a rectangular first hollow portion 441a and a second hollow portion 441b are provided, respectively. The first hollow portion 441a is arranged so as to cover the prospective surface of the grating channel 452. The second hollow portion 441b is arranged on the indoor side X2 of the first hollow portion 441a and protrudes toward the indoor side X2 with respect to the facing material 45 of the second shoji 4. A partition wall 441c extending in the prospective direction is formed between the first hollow portion 441a and the second hollow portion 441b.

[0066] In the vertical frame body 441 on the door end side, an outdoor prospective wall portion 441d arranged on the outdoor side X1 of the first hollow portion 441a and an indoor prospective wall portion 441e arranged on the indoor side X2 of the second hollow portion 441b are each formed to be thicker in the prospective direction than other wall portions extending in the prospective direction.

[0067] The end portion on the outdoor side X1 of the vertical frame body 441 on the door end side protrudes toward the outdoor side X1 with respect to the facing material 45. On the end portion on the outdoor side X1 of the vertical frame body 441 on the door end side, a support piece 4411 protrudes in the finding direction toward the door tip side (the left side in FIG. 6) with respect to the first hollow portion 441a. The support piece 4411 is in contact with the grating channel 452 on the door end side from the outdoor side X1.

[0068] A concave groove portion 4412 is formed on the outdoor side X1 of the support piece 4411 in the vertical frame body 441 on the door end side. The concave groove portion 4412 is formed to be recessed from the door tip side (the left side in FIG. 6) toward the door end side (the right side in FIG. 6) along the support piece 4411. The concave groove portion 4412 has a shape that opens toward the door tip side.

[0069] The resin cover 442 is attached so as to cover the prospective surface and the indoor finding surface of the door end side vertical frame body 441. The resin cover 442 has an inner prospective wall portion 442a and an outer prospective wall portion 442b that are arranged so as to cover the left and right prospective surfaces of the door end side vertical frame body 441, and an indoor finding wall portion 442c that is arranged so as to cover the indoor finding surface of the door end side vertical frame body 441. The inner prospective wall portion 442a and the outer prospective wall portion 442b are arranged parallel to each other and extend in the prospective direction.

[0070] The end portion of the inner prospective wall portion 442a on the outdoor side X1 abuts against the grating channel 452 on the door end side from the indoor side X2 and sandwiches and supports the facing material 45 between it and the support piece 4411. The outer prospective wall portion 442b extends in the prospective direction so as to cover the entire outer prospective surface of the door end side vertical frame body 441. The indoor finding wall portion 442c has a width that can cover the door end side vertical frame body 441 and the spacer 451 of the facing material 45 from the indoor side X2. Since the door end side vertical frame body 441 and the spacer 451 are difficult to be visually recognized from the indoor side X2, the design property and heat insulation property of the door end side of the second shoji 4 are improved.

[0071] The door end side vertical frame 64 of the fourth shoji 6 is composed of a metal door end side vertical frame body 641 and a resin cover 642.

[0072] The door end side vertical frame body 641 is provided so as to cover the prospective surface of the grating channel 652 on the door end side of the facing material 65. A hollow portion 641a is provided inside the door end side vertical frame body 641.

[0073] At the end portion of the door end side vertical frame body 641 on the outdoor side X1, a support piece 6411 projects in the finding direction toward the door tip side (the right side in FIG. 6) from the hollow portion 641a. The support piece 6411 abuts against the grating channel 652 on the door end side from the outdoor side X1.

[0074] At the end of the indoor side X2 of the door butt side vertical frame body 641, a protruding piece 6412 protruding toward the door tip side (the right side in FIG. 6) is formed. The protruding piece 6412 forms a labyrinth structure by being inserted into a concave groove portion 4412 provided on the outdoor side X1 of the door butt side vertical frame 44 of the second shoji 4 when the second shoji 4 and the fourth shoji 6 are in the closed state.

[0075] At the end of the indoor side X2 of the door butt side vertical frame body 641, an elastic fin member 6413 protruding toward the indoor side X2 is attached to the outside in the finding direction (the left side in FIG. 6) from the protruding piece 6412. The fin member 6413 contacts the support piece 4411 of the door butt side vertical frame 44 of the second shoji 4 from the outdoor side X1 when the second shoji 4 and the fourth shoji 6 are in the closed state, and forms an airtight portion between the door butt side vertical frames 44 and 64.

[0076] The resin cover 642 is attached so as to protrude from the end of the indoor side X2 of the door butt side vertical frame body 641 toward the inner side in the prospective direction (the right side in FIG. 6). The resin cover 642 abuts on the grating channel 652 on the door butt side of the fourth shoji 6 from the indoor side X2, and sandwiches and supports the face material 65 between it and the support piece 6411. The resin cover 642 covers the spacer 651 of the face material 65 from the indoor side X2. Since the spacer 651 is difficult to be visually recognized from the indoor side X2, the design and heat insulation properties on the door butt side of the fourth shoji 6 are improved.

[0077] The lateral width W3 of the summons portion 12 when the fitting 1 is viewed from the indoor side X2 is the lateral width of the indoor side finding wall portion 442c of the resin cover 442 on the door butt side vertical frame 44 of the second shoji 4. The lateral width of the door butt side vertical frame 64 of the fourth shoji 6 is equal to the lateral width of the indoor side finding wall portion 442c of this resin cover 442. Therefore, when the fitting 1 is viewed from the indoor side X2 in the closed state of the second shoji 4 and the fourth shoji 6, the door butt side vertical frame 64 of the fourth shoji 6 is completely hidden and arranged on the outdoor side X1 of the door butt side vertical frame 44 of the second shoji 4.

[0078] As shown in FIGS. 2, 4 to 6, the outdoor finding wall portions 3333, 4333, 5414, 6414 that constitute the respective outdoor finding surfaces of the leading-side vertical frames 33 of the first shoji 3, the leading-side vertical frames 43 of the second shoji 4, the trailing-side vertical frames 54 of the third shoji 5, and the trailing-side vertical frames 64 of the fourth shoji 6 are arranged at the same position in the prospective direction of the fitting 1. That is, the outdoor finding wall portions 3333, 4333, 5414, 6414 are arranged on the same plane along the finding direction.

[0079] Next, the first screen door 7 and the second screen door 8 will be described. The first screen door 7 and the second screen door 8 slide horizontally along the same screen door rails 213, 223. When the fitting 1 is viewed from the indoor side X2, the first screen door 7 is arranged on the left side, and the second screen door 8 is arranged on the right side.

[0080] As shown in FIGS. 2 and 3, the first screen door 7 includes an upper frame 71 and a lower frame 72 that extend horizontally, a leading-side vertical frame 73 that extends vertically on the leading side (the right side in FIG. 2), and a trailing-side vertical frame 74 that extends vertically on the trailing side (the left side in FIG. 2). A net body 75 is stretched inside a frame body 70 that is rectangularly framed by these. The leading-side vertical frame 73 of the first screen door 7 is the leading-side vertical frame for the first screen door, and the trailing-side vertical frame 74 is the trailing-side vertical frame for the first screen door.

[0081] As shown in FIGS. 2 and 4, when the first to fourth shojis 3 to 6 are in the closed state and the first screen door 7 and the second screen door 8 are butted against each other at the center in the left-right direction of the frame body 2, the leading-side vertical frame 73 of the first screen door 7 is arranged on the outdoor side X1 of the leading-side vertical frame 33 of the first shoji 3, and the trailing-side vertical frame 74 is arranged on the outdoor side X1 of the trailing-side vertical frame 54 of the third shoji 5.

[0082] As shown in Fig. 4, a buffer member 731 protruding toward the indoor side X2 is provided on the door tip side vertical frame 73 of the first screen door 7. The buffer member 731 is, for example, mohair or packing. The buffer member 731 is disposed at the end on the outer side in the finding direction (the right side in Fig. 4) of the door tip side vertical frame 73. The buffer member 731 abuts against the outdoor side finding wall portion 3333 that forms the outdoor side finding surface of the door tip side vertical frame 33 of the first shoji 3 from the outdoor side X1.

[0083] As shown in Fig. 5, a buffer member 741 protruding toward the indoor side X2 is provided on the door butt side vertical frame 74 of the first screen door 7. The buffer member 741 is, for example, mohair or packing. The buffer member 741 is disposed at the end on the outer side in the finding direction (the left side in Fig. 5) of the door butt side vertical frame 74. The buffer member 741 abuts against the door butt side vertical frame 54 of the third shoji 5 from the outdoor side X1. Specifically, the buffer member 741 abuts against the outdoor side finding wall portion 5414 of the door butt side vertical frame body 541 that forms the outdoor side finding surface of the door butt side vertical frame 54, or against the support piece 5411 that is continuous with the outdoor side finding wall portion 5414 in the finding direction, from the outdoor side X1.

[0084] Similar to the first screen door 7, the second screen door 8 has a net body 85 stretched inside a frame body 80 that is rectangularly framed by a top frame and a bottom frame (not shown) extending in the horizontal direction, a door tip side vertical frame 83 extending in the vertical direction on the door tip side (the left side in Fig. 2), and a door butt side vertical frame 84 extending in the vertical direction on the door butt side (the right side in Fig. 2). The door tip side vertical frame 83 in the second screen door 8 is a door tip side vertical frame for the second screen door, and the door butt side vertical frame 84 is a door butt side vertical frame for the second screen door.

[0085] As shown in Figs. 2 and 4, when the first shoji 3 to the fourth shoji 6 are in the closed state and the first screen door 7 and the second screen door 8 are butted against each other at the center in the left - right direction of the frame body 2, the door tip side vertical frame 83 of the second screen door 8 is disposed on the outdoor side X1 of the door tip side vertical frame 43 of the second shoji 4, and the door butt side vertical frame 84 is disposed on the outdoor side X1 of the door butt side vertical frame 64 of the fourth shoji 6.

[0086] As shown in FIG. 4, a buffer member 831 protruding toward the indoor side X2 is provided on the leading end side vertical frame 83 of the second screen door 8. The buffer member 831 is, for example, mohair or packing. The buffer member 831 is disposed at the end on the outer side (the left side in FIG. 4) in the finding direction in the leading end side vertical frame 83. The buffer member 831 abuts against the outdoor side finding wall portion 4333 that forms the outdoor side finding surface of the leading end side vertical frame 43 of the second shoji 4 from the outdoor side X1.

[0087] As shown in FIG. 6, a buffer member 841 protruding toward the indoor side X2 is provided on the trailing end side vertical frame 84 of the second screen door 8. The buffer member 841 is, for example, mohair or packing. The buffer member 841 is disposed at the end on the outer side (the right side in FIG. 6) in the finding direction in the trailing end side vertical frame 84. The buffer member 841 abuts against the trailing end side vertical frame 64 of the fourth shoji 6 from the outdoor side X1. Specifically, the buffer member 841 abuts against the outdoor side finding wall portion 6414 of the trailing end side vertical frame body 641 that forms the outdoor side finding surface of the trailing end side vertical frame 64, or against the support piece 6411 that is continuous with the outdoor side finding wall portion 6414 in the finding direction, from the outdoor side X1.

[0088] Here, the fact that the buffer members 731, 741, 831, 841 "abut" is not necessarily limited to being in complete contact with the mating member, and also includes cases where there is a minute gap between the buffer members and the mating member.

[0089] FIG. 7 shows a state in which only the second shoji 4 is moved in the opening direction in the furniture 1. As a result, the space between the first shoji 3 and the second shoji 4 is opened. At this time, the second screen door 8 is slightly moved leftward from the state shown in FIG. 2, and the buffer member 831 of the door tip side vertical frame 83 of the second screen door 8 is brought into contact with the outdoor side protruding portion 333 of the door tip side vertical frame 33 of the first shoji 3 from the outdoor side X1, and the buffer member 841 of the door butt side vertical frame 84 is brought into contact with the door butt side vertical frame 64 of the fourth shoji 6 from the outdoor side X1. Thus, the space between the first shoji 3 and the second shoji 4 can be shielded only by the second screen door 8. In this case, it is not necessary to maintain the state in which the first screen door 7 and the second screen door 8 are butted against each other. Therefore, as shown in FIG. 7, the first screen door 7 can be arranged away from the second screen door 8.

[0090] FIGS. 8 to 12 show butting portions 10A to 10E according to another embodiment. Since the parts denoted by the same reference numerals as the above-described butting portion 10 indicate the parts having the same configuration, the description thereof is incorporated by reference to the description of the butting portion 10 and is omitted in the following description. In FIGS. 8 to 12, the illustration of the first screen door 7 and the second screen door 8 is omitted.

[0091] The butting portion 10A shown in FIG. 8 has handle portions 3336 and 4336 on the outdoor side protruding portions 333 and 433 of the door tip side vertical frames 33 and 43 of the first shoji 3 and the second shoji 4, respectively. The handle portions 3336 and 4336 are formed over the entire length in the longitudinal direction of the outdoor side protruding portions 333 and 433. The handle portions 3336 and 4336 are formed by recessing stepwise from the outdoor side finding wall portions 3333 and 4333 to the outer looking wall portions 3332 and 4332 of the outdoor side protruding portions 333 and 433. As a result, since the gap S of the butting portion 10A widens toward the outdoor side X1, a wider handle space can be formed on the outdoor side X1 without changing the overall lateral width of the butting portion 10A.

[0092] The butting portion 10B shown in Fig. 9 has hand-holding portions 3337 and 4337 on the outdoor-side protruding portions 333 and 433 of the vertical frames 33 and 43 at the door end of the first shoji 3 and the second shoji 4, respectively. The hand-holding portions 3337 and 4337 are formed over the entire length in the longitudinal direction of the outdoor-side protruding portions 333 and 433. The hand-holding portions 3337 and 4337 are formed by recessing the end portions on the outdoor side X1 of the inner projected wall portions 3331 and 4331 of the outdoor-side protruding portions 333 and 433 toward the outer projected wall portions 3332 and 4332. The lateral widths of the outdoor-side projected wall portions 3333 and 4333 of the outdoor-side protruding portions 333 and 433 are maintained. Thereby, the hand-holding portions 3337 and 4337 can be formed on the outdoor side X1 without changing the external appearance shape of the butting portion 10B when viewed from the outdoor side X1.

[0093] In the butting portion 10B, no gap is formed between the indoor-side protruding portions 332 and 432 of the vertical frames 33 and 43 at the door end. The end portions on the indoor side X2 of the indoor-side protruding portions 332 and 432 are formed to be in contact with each other. Specifically, the end portions on the indoor side X2 of the protruding portion main bodies 3321 and 4321 and the resin covers 3322 and 4322 of the indoor-side protruding portions 332 and 432 project in a rectangular shape in the projected direction so as to butt against each other and are in contact with each other. Thereby, since no gap is visually recognized from the indoor side X2 of the butting portion 10B, the design property of the indoor side X2 of the fitting 1 is further improved.

[0094] The butting portion 10C shown in Fig. 10 has hand-holding portions 3338 and 4338 on the outdoor-side protruding portions 333 and 433 of the vertical frames 33 and 43 at the door end, respectively. The hand-holding portions 3338 and 4338 are formed over the entire length in the longitudinal direction of the outdoor-side protruding portions 333 and 433. The hand-holding portions 3338 and 4338 are formed by recessing the outdoor-side projected wall portions 3333 and 4333 of the outdoor-side protruding portions 333 and 433 toward the indoor side X2.

[0095] At the ends of the outdoor-facing prospective wall portions 3332 and 4332 of the outdoor protrusions 333 and 433 on the outdoor side X1, hollow-shaped outdoor elastic members 3339 and 4339 that block the gap S on the outdoor side X1 are respectively attached. The outdoor elastic members 3339 and 4339 are formed symmetrically on the left and right by an elastic material such as rubber. The outdoor elastic members 3339 and 4339 are formed over the entire length in the longitudinal direction of the outdoor protrusions 333 and 433, protrude in the finding direction, and are in contact with each other. Thereby, the airtightness of the outdoor side X1 of the butting portion 10C is further improved. When closing the first shoji 3 and the second shoji 4, even if a finger is caught between the door tip side vertical frames 33 and 43 on the outdoor side X1, since the outdoor elastic members 3339 and 4339 elastically bend, it is difficult to cause pain.

[0096] On the indoor protrusions 332 and 432 of the door tip side vertical frames 33 and 43 of the butting portion 10C on the indoor side, hollow-shaped indoor elastic members 3325 and 4325 that block the gap S on the indoor side X2 are respectively attached. The indoor elastic members 3325 and 4325 are formed symmetrically on the left and right by an elastic material such as rubber. The indoor elastic members 3325 and 4325 are formed over the entire length in the longitudinal direction of the indoor protrusions 332 and 432, protrude in the finding direction, and are in contact with each other. The indoor elastic members 3325 and 4325 are attached to the protrusion main bodies 3321 and 4321 of the indoor protrusions 332 and 432. The resin covers 3322 and 4322 of the indoor protrusions 332 and 432 are divided into a first cover portion 3322A and 4322A and a second cover portion 3322B and 4322B by sandwiching the indoor elastic members 3325 and 4325. Thereby, the airtightness of the indoor side X2 of the butting portion 10C is further improved. When closing the first shoji 3 and the second shoji 4, even if a finger is caught between the door tip side vertical frames 33 and 43 on the indoor side X2, since the indoor elastic members 3325 and 4325 elastically bend, it is difficult to cause pain.

[0097] The butting portion 10D shown in FIG. 11 is provided with outdoor elastic members 3339 and 4339 of the butting portion 10C shown in FIG. 10 on the outdoor protruding portions 333 and 433 of the vertical frames 33 and 43 on the door tip side in the butting portion 10B shown in FIG. 9. A hollow indoor elastic member 4326 for closing the gap S on the indoor side X2 is attached to the indoor protruding portion 432 of the vertical frame 43 on the door tip side of the butting portion 10D. The indoor elastic member 4326 is formed of an elastic material such as rubber. The indoor elastic member 4326 is formed over the entire length in the length direction of the indoor protruding portion 432, protrudes in the finding direction, and contacts the indoor protruding portion 332 of the vertical frame 33 on the door tip side. The resin cover 4322 of the indoor protruding portion 432 is divided into a first cover portion 4322A and a second cover portion 4322B with the indoor elastic member 4326 interposed therebetween. The indoor elastic member 4326 may be disposed on the side of the indoor protruding portion 332 of the vertical frame 33 on the door tip side and provided so as to contact the indoor protruding portion 432 of the vertical frame 43 on the door tip side.

[0098] The butting portion 10E shown in FIG. 12 further has an airtight structure on the door tip side vertical frame main bodies 331 and 431 of the door tip side vertical frames 33 and 43 in the butting portion 10 shown in FIG. 4. Specifically, a protruding piece 3313 extending in the finding direction toward the second shoji 4 is formed over the entire length in the length direction of the door tip side vertical frame 33 of the door tip side vertical frame 33 of the first shoji 3. Outdoor protruding pieces 4312 and indoor protruding pieces 4313 are formed over the entire length in the length direction of the door tip side vertical frame 33 on the door tip side vertical frame main body 431 of the door tip side vertical frame 43 of the second shoji 4. The outdoor protruding piece 4312 and the indoor protruding piece 4313 extend in the finding direction toward the first shoji 3. The outdoor protruding piece 4312 is disposed on the outdoor side X1 rather than the protruding piece 3313 of the first shoji 3, and the indoor protruding piece 4313 is disposed on the indoor side X2 rather than the protruding piece 3313 of the first shoji 3. The protruding piece 3313, the outdoor protruding piece 4312, and the indoor protruding piece 4313 each protrude in the finding direction so as to overlap in the prospective direction in the closed state of the first shoji 3 and the second shoji 4.

[0099] On the surface of the indoor side X2 of the outdoor protruding piece 4312, a fin member 4314 having elasticity protruding toward the indoor side X2 is attached. The fin member 4314 is in contact with the protruding piece 3313 of the first shoji 3 from the outdoor side X1.

[0100] A block-shaped airtight material 4315 is further provided on the door tip side vertical frame body 431. The airtight material 4315 is attached between the outdoor protruding piece 4312 and the indoor protruding piece 4313. A groove portion 4315a for accommodating the protruding piece 3313 of the first shoji 3 is formed on the prospective surface of the airtight material 4315.

[0101] By providing such an airtight structure at the butting portion 10E, the airtightness of the butting portion 10E is further improved. The butting portion 10E has a structure in which the protruding piece 3313, the outdoor protruding piece 4312, and the indoor protruding piece 4313 are arranged so as to overlap in the prospective direction, and the protruding piece 3313 is accommodated in the groove portion 4315a of the airtight material 4315. Therefore, the first shoji 3 and the second shoji 4 can be prevented from moving in the prospective direction with respect to each other. Therefore, the wind pressure resistance performance of the first shoji 3 and the second shoji 4 is further improved. Such an airtight structure is also applicable to the butting portions 10, 10A to 10D.
