One of these holding pieces 51 is provided with two pipes 53 and the other with two shafts 54 protruding therefrom. Then, from the state of FIG. 3 in which the holding piece 51 usually attached to the spine width adjusting portion 1 on the front cover A side is detached from the base portion 52 and the pipe 53 and the shaft 54 are dissociated, the pipe 53 and the shaft 54 are removed. After that, by attaching both pressing pieces 51 to the base portion 52 so as to face each other, as shown in FIG. 3 → FIG. 14 or FIG. 9 → FIG. The binding rod 5x having a fitting depth corresponding to the contact / separation position is formed.

以上の構成において、本実施形態は、前記背幅調節部１、２を所定の背幅位置に固定する固定具６を設けている。 In the above configuration, the present embodiment is provided with the fixture 6 that fixes the spine width adjusting portions 1 and 2 at a predetermined spine width position.

この固定具６は、図２、図４及び図６等に示すように、前記取付機構４の覆板４２の縁部にヒンジ部６ａを介して回転可能に連ねて設けたプレート状のもので、下面に突起６１、６２を有しており、このうち突起６１の先端に前記背板３の取付孔３２の内段部３２ａに係り合い可能な取付爪６１ａを形成している。すなわち、取付機構４の覆板４２は常に背板３に対して一定位置に配置されるため、この固定具６は常に背板３の内面における所定取付位置に取り付けられるものである。突起６１には取付爪６１ａを係り合わせ或いは離脱させる際にヒンジ部６ａから離れる方向の撓み弾性が付与してあり、突起６２は背幅調節部１、２の位置ずれを実質的に規制する強度を有している。 As shown in FIGS. 2, 4, 6, and the like, the fixture 6 is a plate-like member that is rotatably connected to the edge of the cover plate 42 of the mounting mechanism 4 via a hinge portion 6 a. The lower surface has protrusions 61 and 62, and an attachment claw 61 a that can engage with the inner step portion 32 a of the attachment hole 32 of the back plate 3 is formed at the tip of the protrusion 61. That is, since the cover plate 42 of the attachment mechanism 4 is always disposed at a fixed position with respect to the back plate 3, the fixture 6 is always attached to a predetermined attachment position on the inner surface of the back plate 3. The protrusion 61 is provided with flexural elasticity in a direction away from the hinge portion 6a when the attachment claw 61a is engaged or detached, and the protrusion 62 has a strength that substantially regulates the positional deviation of the back width adjusting portions 1 and 2. have.

すなわち、背幅調節部１、２を図３〜図５及び図８に示す最小背幅位置に縮幅して突起６１の取付爪６１ａを図７に示す背板３の取付孔３２に係り合わせた際には、突起６１、６２は図４並びに図６〜図８に示すように背幅調節部１（２）の貫通部１２（２２）に差し込まれて背幅調節部１（２）がその背幅位置に保持され、逆に背幅調節部１、２を図９〜図１１に示す最大背幅位置に拡幅して前記突起６１の取付爪６１ａを図１２に示す背板３の取付孔３２に係り合わせた際には、突起６１、６２は図１０、図１２及び図１３に示すように背幅調節部１（２）の内縁１ｐ（２ｐ）に係り合って背幅調節部１（２）がその背幅位置に保持されるようにしている。つまり、突起６１、６２は本発明に係る共通の関連部として機能し、背幅調節部１、２の内縁１ｐ、２ｐ及び貫通部１２、２２は本発明の被関連部として機能している。 That is, the back width adjusting portions 1 and 2 are contracted to the minimum back width position shown in FIGS. 3 to 5 and 8, and the attachment claws 61a of the protrusion 61 are engaged with the attachment holes 32 of the back plate 3 shown in FIG. 4 and 6 to 8, the protrusions 61 and 62 are inserted into the through-hole 12 (22) of the back width adjusting portion 1 (2), and the back width adjusting portion 1 (2) is inserted. On the contrary, the back width adjusting portions 1 and 2 are widened to the maximum back width position shown in FIGS. 9 to 11, and the mounting claws 61a of the protrusion 61 are attached to the back plate 3 shown in FIG. When engaged with the hole 32, the protrusions 61 and 62 are engaged with the inner edge 1p (2p) of the back width adjusting portion 1 (2) as shown in FIGS. (2) is held in the back width position. That is, the protrusions 61 and 62 function as a common related portion according to the present invention, and the inner edges 1p and 2p of the back width adjusting portions 1 and 2 and the through portions 12 and 22 function as a related portion of the present invention.

なお、この固定具６は、ヒンジ部６ａによって係り合い位置から非係り合い位置に移動した図６の位置にクリックストップされ、覆板４２に対して起立した状態を保持するようになっている。 The fixture 6 is click-stopped to the position shown in FIG. 6 which has been moved from the engagement position to the non-engagement position by the hinge portion 6 a, and is held upright with respect to the cover plate 42.

ところで、上記の構成のままだと、拡幅状態において、綴じ具５の綴じ杆５ｘを構成する軸５４が図１４→図１５に示すようにパイプ５３から拡幅寸法分だけ引き出された状態となり、このままではパイプ５３と軸５４の間に出来る段差が閲覧時に紙葉類を通過させる際の引っ掛かりになるとともに、強度的にも不十分となるのみならず、軸５４が付帯している側の押さえ片５１を抜き取って紙葉類の加除作業を行う際に、綴じ込んでいる紙葉類が多い場合にはパイプの長さが足りずに紙葉類が外れて散乱する事態が起こり得る。 By the way, if it is the above configuration, in the widened state, the shaft 54 constituting the binding rod 5x of the binding tool 5 is pulled out from the pipe 53 by the widened dimension as shown in FIGS. Then, the step formed between the pipe 53 and the shaft 54 becomes a catch when the paper sheet is passed during browsing, and not only is the strength insufficient, but the holding piece on the side where the shaft 54 is attached. When the paper 51 is removed and the paper sheets are added and removed, if there are many paper sheets that are bound, there is a possibility that the paper sheets may come off and scatter due to insufficient pipe length.

そこで、本実施形態は、図３及び図９に示すように、背幅調節に伴って開閉する位置に格納空間Ｓを設け、この格納空間Ｓに延長パイプ５５を格納して、背幅を拡幅した際にその格納空間Ｓを開放して延長パイプ５５を取り出し得るようにしている。そして、その延長パイプ５５を既設パイプ５３に嵌合させることによって、図１６に示すように当該既設パイプ５３から突出する軸５４を延長パイプ５５で覆いつつ綴じ杆５ｘを延長できるようにしている。 Therefore, in the present embodiment, as shown in FIGS. 3 and 9, a storage space S is provided at a position that opens and closes as the back width is adjusted, and the extension pipe 55 is stored in the storage space S to widen the back width. In this case, the storage space S is opened so that the extension pipe 55 can be taken out. Then, by fitting the extension pipe 55 to the existing pipe 53, the binding rod 5x can be extended while the shaft 54 protruding from the existing pipe 53 is covered with the extension pipe 55 as shown in FIG.

格納空間Ｓは、ベース部５２と背板３の内面との間に形成されたもので、元々ベース部５２は外縁側に軸受５２ａ等の機構部を形成する関係上、中央部がせり上がった中空部５２ｘになっている。そこで、この中空部５２ａを利用し、対する背板３の内面に凹部３４を形成するとともに、背幅調節部１、２の内縁１ｐ、２ｐのうち凹部３４に対応する部位を切除して（図９における符合１ｒ、２ｒ参照）、中空部５２ｘと凹部３４との間に格納空間Ｓとして機能する空隙を確保している。凹部３４内には延長パイプ５５を係り合わせる挟持片３４ａが起立しており、この挟持片３４ａに図１７に示すように延長パイプ５５を嵌め込んで保持させることができるようにしている。勿論、この状態で左右のベース部５２の内縁同士を突き合わせた際には、ベース部５２は延長パイプ５５と干渉せずに格納空間Ｓの上方を覆うことができる。 The storage space S is formed between the base portion 52 and the inner surface of the back plate 3, and the base portion 52 originally has a central portion raised due to the formation of a mechanism portion such as a bearing 52a on the outer edge side. It is a hollow portion 52x. Accordingly, the hollow portion 52a is used to form the concave portion 34 on the inner surface of the corresponding back plate 3, and the portion corresponding to the concave portion 34 is cut out of the inner edges 1p, 2p of the back width adjusting portions 1, 2 (see FIG. 9, a gap functioning as the storage space S is secured between the hollow portion 52 x and the concave portion 34. A holding piece 34a for engaging the extension pipe 55 stands up in the recess 34, and the extension pipe 55 can be fitted and held in the holding piece 34a as shown in FIG. Of course, when the inner edges of the left and right base portions 52 are brought into contact with each other in this state, the base portion 52 can cover the upper portion of the storage space S without interfering with the extension pipe 55.

一方、延長パイプ５５は、図１８に示すようにステンレス等の薄板鋼鈑を円筒状に塑性変形加工して、長手方向に延びる縁部間を開きつつ半径方向に弾性変形するように構成したもので、図１６及び図１８に示すように既設パイプ５３に対して拡幅寸法分だけ長く、且つやや大径に設けられて、半径方向に弾性的に拡径しながら既設パイプ５３に外嵌されるように設定している。 On the other hand, as shown in FIG. 18, the extension pipe 55 is formed by plastically deforming a thin steel plate made of stainless steel or the like into a cylindrical shape and elastically deforming in the radial direction while opening the edges extending in the longitudinal direction. Thus, as shown in FIGS. 16 and 18, it is longer than the existing pipe 53 by a width-enhancing dimension and is slightly larger in diameter, and is externally fitted to the existing pipe 53 while elastically expanding in the radial direction. It is set as follows.

そして、既設パイプ５３の押さえ片側端部近傍に図９、図１８及び図１９（ａ）に示すような外向きに凹となる凹凸関連部５３ａを設けるとともに、延長パイプ５５の対応部位である嵌合始端側に内向きに凸となる凹凸関連部５５ａを設け、さらに延長パイプ５５の凹凸関連部５５ａ近傍に一部波形をなす変形誘発部５５ｂを形成し、この変形誘発部５５ｂによって当該凹凸関連部５５ａ及びその周辺部の半径方向への弾性変形を誘発するようにしている。 Then, in the vicinity of the holding piece side end portion of the existing pipe 53, an uneven portion 53a that is concave outward as shown in FIGS. 9, 18, and 19A is provided, and a fitting that is a corresponding portion of the extension pipe 55 is provided. An unevenness-related portion 55a that protrudes inward on the starting end side is provided, and a deformation inducing portion 55b having a partial waveform is formed in the vicinity of the unevenness-related portion 55a of the extension pipe 55, and the unevenness-related portion is formed by the deformation inducing portion 55b. The elastic deformation in the radial direction of the portion 55a and its peripheral portion is induced.

また、図１８に示す延長パイプ５５のうち既設パイプ５３と実質的に嵌合しない延長部分に、延長パイプ５５の内径を狭める狭窄部として、図１６、図１８及び図１９（ｂ）に示すように延長パイプ５５の長手方向に沿って延びる複数の内向きの突条５５ｃを外周等角位置に打設により設けている。 Further, as shown in FIGS. 16, 18 and 19 (b), a narrowed portion for narrowing the inner diameter of the extension pipe 55 is formed in an extension portion of the extension pipe 55 shown in FIG. A plurality of inwardly extending ridges 55c extending along the longitudinal direction of the extension pipe 55 are provided in the outer peripheral equiangular position by driving.

以上のように構成される本実施形態は、表表紙Ａ及び裏表紙Ｂの内縁に一対の背幅調節部１、２を連ねて設け、これらの背幅調節部１、２を接離方向に沿って背板３にスライド可能に配置することにより異なる背幅位置をとらしめるようにしたものである。そして、背板３の内面側における所定取付位置に固定具６を取り付け可能として、取り付けに伴い固定具６の一部に設定した関連部たる突起６１、６２を背幅調節部１、２の一部に設定した被関連部たる貫通部１２、２２或いは内縁１ｐ、２ｐに係り合わせるようにし、このように被関連部を複数箇所に設けることによって、拡幅位置で一方の被関連部である内縁１ｐ、２ｐが係り合いに関与し幅狭位置で他方の被関連部である貫通部１２、２２が係り合いに関与するように構成したものである。 In the present embodiment configured as described above, a pair of spine width adjusting units 1 and 2 are provided on the inner edges of the front cover A and the back cover B, and the spine width adjusting units 1 and 2 are arranged in the contact / separation direction. A different back width position is obtained by slidably arranging the back plate 3 along the back. Then, the fixture 6 can be attached to a predetermined attachment position on the inner surface side of the back plate 3, and the protrusions 61 and 62 which are related portions set to a part of the fixture 6 along with the attachment are provided on one of the back width adjusting portions 1 and 2. The inner edge 1p which is one of the related parts at the widened position is obtained by engaging with the through parts 12 and 22 or the inner edges 1p and 2p which are set as the related parts, and providing the related parts in a plurality of places in this way. 2p is involved in the engagement, and the penetrating parts 12 and 22 which are the other related parts in the narrow position are involved in the engagement.

このように構成すると、背幅調節部１、２を通常位置である幅狭位置から拡幅位置に再固定して使用することができるので、単に閲覧のために拡幅する場合に比べて、実質的な綴じ込み量を有効に可変とすることができる。また、予め多くの紙葉類の綴じ込みが予定される場合にも、綴じ込み量が少ない間は背幅調節部１、２を幅狭位置に調整しておけば棚等の保管場所に多くのデッドスペースが生じることも有効に解消することができる。その上、背板３の内面側から一定の取付位置に固定具６を固定するので、机上にて見開き状態で背幅変更作業及び固定作業を簡単に行うことができ、背板３に必要以上の取付孔等を設けることも回避して、加工の便等も有効に向上させることができる。 With this configuration, the spine width adjusting units 1 and 2 can be used by re-fixing from the narrow position, which is the normal position, to the widened position. The amount of binding can be made variable effectively. Also, even when a large number of paper sheets are to be bound in advance, if the back width adjusting units 1 and 2 are adjusted to a narrow position while the amount of binding is small, many dead places are stored in storage places such as shelves. It is possible to effectively eliminate the generation of space. In addition, since the fixture 6 is fixed at a fixed mounting position from the inner surface side of the back plate 3, the back width can be easily changed and fixed in a spread state on the desk, and the back plate 3 is more than necessary. It is also possible to effectively improve the processing convenience and the like.

具体的には、背幅調節部１、２の背板３に対する可動範囲を規制した上で、固定具６に設けた突起６１、６２を共通の関連部とする一方、背幅調節部１、２の内縁１ｐ、２ｐ及び当該内縁１ｐ、２ｐ近傍に設けた貫通部１２、２２をそれぞれ被関連部として、最大背幅位置で固定具６の突起６１、６２を背幅調節部１、２の内縁１ｐ、２ｐに係り合わせ、最小背幅位置で固定具６の突起６１、６２を背幅調節部１、２の貫通部１２、２２に係り合わせるようにしている。このように、背幅調節部１、２の内縁１ｐ、２ｐを利用することで、少なくとも背幅調節部１、２に設ける貫通部１２、２２の数を減らすことができ、背幅調節部１、２が比較的幅狭であるためにスライド方向に沿って多数の貫通部を設けられない事情がある場合等に特に有効な構成として採用することができる。 Specifically, after restricting the movable range of the back width adjusting portions 1 and 2 with respect to the back plate 3, the protrusions 61 and 62 provided on the fixture 6 are used as a common related portion, while the back width adjusting portion 1 and The inner edges 1p and 2p of the two and the through portions 12 and 22 provided in the vicinity of the inner edges 1p and 2p are related parts, respectively, and the protrusions 61 and 62 of the fixture 6 are connected to the back width adjusting parts 1 and 2 at the maximum back width position. The protrusions 61 and 62 of the fixture 6 are engaged with the through-holes 12 and 22 of the back width adjusting portions 1 and 2 at the minimum back width position in association with the inner edges 1p and 2p. In this way, by using the inner edges 1p and 2p of the back width adjusting portions 1 and 2, the number of the through portions 12 and 22 provided in at least the back width adjusting portions 1 and 2 can be reduced. Since 2 is relatively narrow, it can be employed as a particularly effective configuration when there are circumstances in which a large number of through portions cannot be provided along the sliding direction.

また、固定具６を、背幅調節部１、２のスライド動作を妨げずかつ背板３から離脱し得ないように当該背板３に付帯させ、その付帯状態を保って背板３の所定取付位置への脱着を可能としているため、固定具６が常に背板３に付帯することとなり、誰が操作しても固定具６を背板３の一定の取付位置に取り付ける操作を有効に行わせることができる。 Further, the fixture 6 is attached to the back plate 3 so as not to interfere with the sliding operation of the back width adjusting portions 1 and 2 and cannot be detached from the back plate 3, and the back plate 3 is kept in a predetermined state while maintaining the attached state. Since the attachment / detachment to the attachment position is possible, the fixture 6 is always attached to the back plate 3, and the operation of attaching the fixture 6 to the fixed attachment position of the back plate 3 is effectively performed by anyone. be able to.

具体的には、背幅調節部１、２と背板３との間に、支持杆４１を背幅調節部１、２に貫通させた状態で背幅調節部１、２を背板３に離脱しないように取り付ける取付機構４を備え、この支持杆４１の一端側に固定具６を支持させているので、固定具６を支持杆４１を介して背板３に確実に付帯させることができ、構造も簡素なものに止どめることができる。 Specifically, between the back width adjusting portions 1 and 2 and the back plate 3, the back width adjusting portions 1 and 2 are attached to the back plate 3 with the support rod 41 penetrating the back width adjusting portions 1 and 2. Since the attachment mechanism 4 is mounted so as not to be detached and the fixing tool 6 is supported on one end side of the support rod 41, the fixing tool 6 can be reliably attached to the back plate 3 via the support rod 41. The structure can be kept simple.

その取付機構４も、支持杆４１の一端側において背板３に対し所定距離を隔てて対向配置される覆板４２を有し、その覆板４２に固定具６を可動に支持させて、関連部である突起６１、６２を被関連部である貫通部１２、２２や内縁１ｐ、２ｐに対して脱着させるようにしているので、背幅調節部１、２が支持杆４１から外れることを覆板４２によって禁止することができると同時に、固定具６の取付先もこの覆板４２上に容易に確保することができる。 The attachment mechanism 4 also has a cover plate 42 that is disposed to face the back plate 3 at a predetermined distance on one end side of the support rod 41, and the fixing plate 6 is movably supported by the cover plate 42 and related. Since the projections 61 and 62 that are the parts are detached from the through parts 12 and 22 that are the related parts and the inner edges 1p and 2p, it is possible to prevent the back width adjusting parts 1 and 2 from being detached from the support rod 41. At the same time it can be prohibited by the plate 42, the attachment destination of the fixture 6 can be easily secured on the cover plate 42.

特に固定具６が、ヒンジ部６ａを介して覆板４２に回転可能に支持されているので、ぶれの少ない回転動作を通じて良好な操作性を保ちつつ、覆板からの脱落、紛失を有効に防止することができ、また、取り付け位置から取り外し位置に移動した際にヒンジ部６ａによってクリックストップされるようにしているので、固定具６を取り外し位置に待機させた状態で背幅調節部１、２の操作を有効に行うことができる。 In particular, since the fixture 6 is rotatably supported by the cover plate 42 via the hinge portion 6a, it is possible to effectively prevent dropping and loss from the cover plate while maintaining good operability through a rotational operation with little shaking. In addition, when moving from the attachment position to the removal position, the hinge portion 6a is click-stopped. Can be performed effectively.

さらに、取付機構４が、支持杆４１をガイド部たる長孔４２ａ、３１に係り合わせており、これら支持杆４１と長孔４２ａ、３１とで背板３に対する背幅調節部１、２の移動を誘導するようにしているので、別途にスライドガイド部を設けることなく、固定具６の支持構造を利用して背幅調節部１、２のスライド動作を円滑に行わせることができ、構造の複雑化を有効に回避することが可能となる。 Further, the attachment mechanism 4 is engaged with the long holes 42a and 31 that serve as the guide portion of the support rod 41, and the movement of the back width adjusting portions 1 and 2 with respect to the back plate 3 by the support rod 41 and the long holes 42a and 31. Therefore, it is possible to smoothly slide the back width adjusting portions 1 and 2 using the support structure of the fixture 6 without providing a separate slide guide portion, It becomes possible to effectively avoid complication.

さらにまた、関連部である突起６１の先端に取付爪６１ａを設けるとともに、背板３の所定位置に取付孔３２を設け、突起６１を被関連部である内縁１ｐ、２ｐや貫通部１２、２２に係り合わせるに伴い、取付爪６１ａを取付孔３２に掛け止めて、突起６１を所要の係り合い位置に保持するようにしており、関連部として機能する突起６１の先端をそのまま固定具６を背板３に取り付ける取付部材として用いることができる。このため、構造の簡素化の実効を図ることができ、また、突起６１を貫通部１２、２２や内縁１ｐ、２ｐに係り合わせるための背幅固定操作がそのまま固定具６の取り付け操作に連なるため、一連の操作によって背幅変更作業の便を有効に向上させることができる。 Furthermore, an attachment claw 61a is provided at the tip of the projection 61 which is a related portion, and an attachment hole 32 is provided at a predetermined position of the back plate 3, and the projection 61 is connected to the inner edges 1p and 2p which are related portions and the through portions 12 and 22. As a result, the mounting claw 61a is hooked on the mounting hole 32 so that the projection 61 is held at the required engagement position. It can be used as an attachment member attached to the plate 3. For this reason, the simplification of the structure can be achieved, and the back width fixing operation for engaging the protrusion 61 with the through portions 12 and 22 and the inner edges 1p and 2p is directly connected to the mounting operation of the fixture 6. The stool for changing the back width can be effectively improved by a series of operations.

以上において、本実施形態のファイルＦに付帯する綴じ具５は、ベース部５２を介して一対の押さえ片５１を、各々対応する背幅調節部に少なくとも一方の押さえ片５１が着脱可能であるように取り付け、これらの押さえ片５１の一方より突出させた軸５４と他方より突出させたパイプ５３とを嵌合させて背幅に応じた嵌合深さの綴じ杆を形成するパイプ構造をなし、この綴じ具５のベース部５２が、背幅一定のファイルを構成する綴じ具のベース部を半割にしたものと同様の構成をなしている。このため、背幅を狭く調節した際には通常の綴じ具を用いたファイルと全く同じ背幅、同じ綴じ込み量のものとして取り扱うことができ、取扱いに便利となる上に、綴じ具も作り易いものになる。 In the above, the binding tool 5 attached to the file F of the present embodiment is configured such that the pair of pressing pieces 51 can be attached to and detached from the corresponding back width adjusting parts via the base portion 52, respectively. And a pipe structure that forms a binding rod having a fitting depth according to the back width by fitting a shaft 54 protruding from one of these pressing pieces 51 and a pipe 53 protruding from the other, The base portion 52 of the binding tool 5 has the same configuration as that obtained by halving the base portion of the binding tool that constitutes a file having a constant back width. For this reason, when the back width is adjusted narrowly, it can be handled with the same back width and the same binding amount as a file using a normal binding tool, which is convenient for handling and easy to make a binding tool. Become a thing.

なお、各部の具体的な構成は、上述した実施形態のみに限定されるものではない。 The specific configuration of each unit is not limited to the above-described embodiment.

例えば、背幅調節部１、２がある程度幅広である場合等には、図２０に示すように、固定具６に設けた突起６１、６２を共通の関連部とするのに対して、背幅調節部１、２に複数の貫通部１１２、１２２を設けて被関連部とし、それらの貫通部１１２、１２２に選択的に突起６１、６２を同じ条件で係り合わせるように構成しても構わない。 For example, when the spine width adjusting portions 1 and 2 are wide to some extent, as shown in FIG. 20, the protrusions 61 and 62 provided on the fixture 6 are used as a common related portion. A plurality of penetrating parts 112 and 122 may be provided in the adjusting parts 1 and 2 as related parts, and the protrusions 61 and 62 may be selectively engaged with the penetrating parts 112 and 122 under the same conditions. .

或いは、背幅調節部１、２の背板３に対する可動範囲が規制されている場合において、図２１に示すように、最大背幅位置（同図（ａ））で固定具１０６の外方端１０６ａを関連部とするとともに背幅調節部１、２の内縁１ｐ、２ｐを前記外方端１０６ａが係り合う被関連部となし、最小背幅位置（同図（ｂ））で固定具６の外方端１０６ａよりも内方に設けた突起１６１を関連部とするとともに背幅調節部１、２の内縁付近に設けた貫通孔２１２、２２２を前記突起１６１が係り合う被関連部となしてもよい。このようにすれば、貫通部２１２、２２２を背幅調節部１、２の内縁１ｐ、２ｐに近い位置に設けても、比較的大きな背幅変化の下に背幅調節部１、２を固定することができる。なお、この場合には、突起１６１の先端に形成される取付爪１６１ａが背板３の厚み方向に対して２段階で取付孔１３２に係り合うようにしておくとよい。 Alternatively, when the movable range of the back width adjusting portions 1 and 2 with respect to the back plate 3 is restricted, as shown in FIG. 21, the outer end of the fixture 106 at the maximum back width position (FIG. 21A). 106a is used as a related portion, and the inner edges 1p and 2p of the back width adjusting portions 1 and 2 are formed as related portions with which the outer end 106a is engaged, and the fixing device 6 is positioned at the minimum back width position (FIG. 5B). The protrusion 161 provided inward from the outer end 106a is used as a related part, and the through holes 212 and 222 provided near the inner edges of the back width adjusting parts 1 and 2 are used as related parts with which the protrusion 161 is engaged. Also good. In this way, even if the penetration parts 212 and 222 are provided at positions close to the inner edges 1p and 2p of the back width adjusting parts 1 and 2, the back width adjusting parts 1 and 2 are fixed under a relatively large back width change. can do. In this case, it is preferable that the attachment claw 161a formed at the tip of the protrusion 161 is engaged with the attachment hole 132 in two stages with respect to the thickness direction of the back plate 3.

また、図２２に示すように、固定具２０６に上記と同様の突起２６１、２６２を設けるものの、この固定具２０６を背板３に対して常に付帯するのではなく離脱可能として、背板３の所定取付位置への脱着動作を行い得るように構成しても、背幅調整前後は必ず背板３に付帯して機能するので部品の紛失の恐れはなく、背板３に対して所定取付位置への取り付け容易性さえ確保すれば、上記に準じた作用効果が奏される。 Further, as shown in FIG. 22, although the fixture 206 is provided with projections 261 and 262 similar to the above, the fixture 206 is not always attached to the back plate 3 but can be detached. Even if it is configured so that it can be attached to and detached from the predetermined mounting position, it always functions along with the back plate 3 before and after adjusting the back width, so there is no risk of losing parts, and the predetermined mounting position with respect to the back plate 3 As long as the ease of attachment to the device is ensured, the same effects as described above can be obtained.
