Note that reference numeral 52 in FIG. 9 denotes a latch.

このうち傾斜角度調整部２は、図１乃至図３に示すように、アーム２１と、障子５１の縦框５１Ａに取付られ、かつアーム２１の一方端に取付けられた可動軸２１Ａを縦框５１Ａの上下方向に摺動可能とする案内部材２２と、窓枠５０の縦枠５１Ａに取付けられ、かつアーム２１の他方端を遊びをもって回動可能に支持する取付具２３と、を有している。   1 to 3, the inclination angle adjusting unit 2 is attached to the arm 21 and the vertical shaft 51A of the shoji 51, and the movable shaft 21A attached to one end of the arm 21 is connected to the vertical shaft 51A. A guide member 22 that is slidable in the vertical direction, and a fixture 23 that is attached to the vertical frame 51A of the window frame 50 and rotatably supports the other end of the arm 21 with play. .

可動軸２１Ａは、幅狭溝２２Ｂの範囲で摺動可能に案内される小外径部２１ａと、この小外径部２１ａの下部に形成され、かつ幅広溝２２Ａの範囲で摺動可能に案内される大外径部２１ｂと、この大外径部２１ｂの下部に形成され、かつ大外径部２１ｂよりもさらに大径の可動軸底部２１ｃと、小外径部２１ａに遊貫され、かつ案内部材２２の表面を押圧する圧縮バネ２１ｄと、を有している。   The movable shaft 21A is formed so as to be slidable in the range of the narrow groove 22B, and is formed in the lower portion of the small outer diameter portion 21a and is slidably guided in the range of the wide groove 22A. A large outer diameter portion 21b, a movable shaft bottom portion 21c formed below the large outer diameter portion 21b and having a larger diameter than the large outer diameter portion 21b, and loosely penetrated by the small outer diameter portion 21a, and A compression spring 21d that presses the surface of the guide member 22.

大外径部２１ｂは、案内部材２２の案内溝の上方の幅広溝２２Ａの範囲で摺動可能となっており、図１１に示すように、幅広溝２２Ａの下端（幅広溝２２Ａと幅狭溝２２Ｂとの境部分）が第１の開放限となり、一段階目の障子５０の倒れの停止が行なわれる。この停止は、障子５０の倒れ角度の小さい場合であり、換気等に小開きするときになされる。   The large outer diameter portion 21b is slidable in the range of the wide groove 22A above the guide groove of the guide member 22, and as shown in FIG. 11, the lower end of the wide groove 22A (the wide groove 22A and the narrow groove). 22B becomes the first opening limit, and the first stage of shoji 50 is stopped from falling. This stop is when the shoji 50 is tilted at a small angle, and is made when it is opened slightly for ventilation or the like.

一方、小外径部２１ａは案内溝の下方の幅狭溝２２Ｂの範囲で摺動可能となっており、幅狭溝２２Ｂの下端が第２の開放限となり、二段階目の障子５０の倒れの停止が行なわれる。この停止は、障子５０の倒れ角度の大きい場合であり、清掃等で大開きするときになされる。   On the other hand, the small outer diameter portion 21a is slidable in the range of the narrow groove 22B below the guide groove. The lower end of the narrow groove 22B becomes the second opening limit, and the second stage shoji 50 falls down. Is stopped. This stop is when the shoji 50 is tilted at a large angle, and is made when the shoji 50 is opened wide by cleaning or the like.

圧縮バネ２１ｄには、その下部に押圧板２１ｅが取付られており、この押圧板２１ｅを介して案内部材２２の表面を押圧するようになっている。押圧板２１ｅは、小外径部２１ａに遊貫されており、圧縮バネ２１ｄにより案内部材２２の表面を押圧することで、可動軸２１Ａ自体を押し上げ、その結果、幅広溝２２Ａの範囲では、図３（１）に示すように、大外径部２１ｂが幅広溝内に摺動可能に案内されると共に、可動軸底部２１ｃが案内部材２２の裏面に摺動可能に係止され、他方、図３（２）に示すように、幅狭溝２２Ｂの範囲では、小外径部２１ａが幅狭溝２２Ｂ内に摺動可能に案内されると共に、大外径部２１ｂが案内部材２２の裏面に摺動可能に係止されるようになっている。   A pressing plate 21e is attached to the lower portion of the compression spring 21d, and the surface of the guide member 22 is pressed through the pressing plate 21e.

また、圧縮バネ２１ｄにより、障子５１を閉める方向に戻せば、可動軸２１Ａが幅狭溝２２Ｂ内から幅広溝２２Ａ内へ移動し、圧縮バネ２１ｄにより大外径部２１ｂが押し上げられて幅広溝２２Ａ内に復帰し、第１の開放限で停止させることができ、さらに障子５１を戻せば障子５１の閉止位置になる。   Further, when the shoji 51 is returned to the closing direction by the compression spring 21d, the movable shaft 21A moves from the narrow groove 22B into the wide groove 22A, and the large outer diameter portion 21b is pushed up by the compression spring 21d to widen the wide groove 22A. Can be stopped at the first opening limit, and when the shoji 51 is returned, the shoji 51 is closed.

圧縮バネ２１ｄにより可動軸底部２１ｃや大外径部２１ｂが案内部材２２の裏面に係止されることにより、第１の開放限（例えば、２０°程度）及び第２の開放限（例えば、４５°程度）において障子５１のガタつきを抑制することもできる。   When the movable shaft bottom portion 21c and the large outer diameter portion 21b are locked to the back surface of the guide member 22 by the compression spring 21d, the first opening limit (for example, about 20 °) and the second opening limit (for example, 45). The backlash of the shoji 51 can also be suppressed at about °.

案内部材２２は、障子５１の縦框５１Ａにそれぞれ取付られており、前述したように、第１の開放限及び第２の開放限の二段階の倒れ角度に停止できるように、幅広溝２２Ａと幅狭溝２２Ｂとの溝幅の異なる案内溝を備えており、幅広溝２２Ａの範囲で大外径部２１ｂが摺動可能に案内され、幅狭溝２２Ｂの範囲で小外径部２１ａが摺動可能に案内されるものである。   The guide members 22 are respectively attached to the vertical rods 51A of the shoji 51. As described above, the wide groove 22A and the wide groove 22A can be stopped so as to be stopped at the two-stage tilt angle of the first opening limit and the second opening limit. A guide groove having a different groove width from the narrow groove 22B is provided. The large outer diameter portion 21b is slidably guided in the range of the wide groove 22A, and the small outer diameter portion 21a is slid in the range of the narrow groove 22B. It is guided so that it can move.

取付具２３は、窓枠５０の縦枠５０Ａに取付けられ、かつアーム２１の他方端を遊びをもって回動可能に支持している。取付具２３は、取付具本体２３Ａと、取付具本体２３Ａの張出部２３Ｂに取付けられた固定ピン２３Ｃを備えており、アーム２１の他方端に形成された孔２１Ｂが固定ピン２３Ｃに遊貫されるようになっている。   The fixture 23 is attached to the vertical frame 50A of the window frame 50, and supports the other end of the arm 21 so as to be rotatable with play. The fixture 23 includes a fixture main body 23A and a fixing pin 23C attached to the overhanging portion 23B of the fixture main body 23A, and a hole 21B formed at the other end of the arm 21 penetrates the fixing pin 23C.
