Description

  The present invention relates to a dimension adjusting member, for example, a dimension adjusting member for forming a wiring storage space or a piping storage space on a foundation floor surface of a building.

  As a conventional dimension adjusting member, for example, a channel member used when constructing a double floor having a wiring storage space on a basic floor surface of a building is known. This channel member is formed in a U-shaped cross section having an upper surface and both side surfaces, and constitutes a double floor when a large amount of wiring (LAN cable etc. is wired) from the incoming line portion of the wall to the wiring storage space. Used to fill gaps between floor panels and walls. Moreover, in the site (construction site) where a double floor is installed, the dimension from the wall to the floor panel is often different for each site. For this reason, at each site, a contractor performs a dimensional adjustment work for cutting the channel member with a circular saw or the like as necessary.

  However, this cutting process sometimes has the following problems. Specifically, when a channel member with a low height dimension is used, the side surface is low, so that the cutting is achieved by cutting the upper surface so that the circular saw blade reaches the lower end of the side surface, and the upper surface and the side surface are joined together. It can be cut and the cutting operation can be completed in a single process. On the other hand, when a channel member with a high height is used, the side surface becomes high, and even if the upper surface is cut, the circular saw blade does not reach the lower end of the side surface, resulting in cutting the both side surfaces and the upper surface. It had to be cut in a single process, resulting in poor workability.

  As a technique for solving the above-mentioned problem, Patent Document 1 proposes a channel member (boundary member) that is disposed in a line entry portion from a wall to a wiring storage space. The channel member (boundary member) described in Patent Literature 1 includes a first wiring insertion member and a second wiring insertion member, and the second wiring insertion member is fitted in the first insertion member so as to be immersive. Is configured to do. According to this configuration, the dimension can be adjusted by sliding the second wiring insertion member with respect to the first insertion member, and the cutting process itself becomes unnecessary, so that the labor of the cutting operation is eliminated.

JP-A-9-144290

  However, the invention described in Patent Document 1 has the following problems. Specifically, the channel member (boundary member) described in Patent Document 1 is different in height from the upper surface of the second wiring insertion member and the upper surface of the first wiring insertion member due to its structure. Therefore, a step is generated at the boundary portion between the first wiring insertion member and the second wiring insertion member. When a finishing material such as a carpet is laid on the channel member in a state where there is a step, there is a problem that the trace of the step becomes visible from the upper surface of the carpet and the appearance is not good. In order to solve this problem, it is necessary to perform some kind of post-processing on the stepped portion. As a result, the work becomes complicated and the workability is not improved.

  Furthermore, the invention described in Patent Document 1 requires two types of members, a first wiring insertion member and a second wiring insertion member, and has another problem that leads to cost increase such as inventory management. .

  The present invention has been made in view of the above problems, and an object thereof is to provide a dimension adjusting member that is inexpensive and can be easily cut into a predetermined dimension.

  The present invention made in order to solve the above-mentioned problem is that the distance between both ends is Lmm in total length, and has an easy-to-cut part in a part thereof, and is used in the state of full-length Lmm or cuts the easy-to-cut part. Thus, in the dimension adjusting member used at the predetermined dimension Xmm, when a portion other than the easy-to-cut portion is located at a distance dimension Xmm from one end, the cutting is performed at a distance dimension Xmm from the other end. It is characterized in that the easy part is positioned.

As described above, the dimension adjusting member of the present invention is easy to cut at the position of the distance dimension Xmm from the other end when the portion other than the easy-to-cut section is located at the position of the distance dimension Xmm from one end. Are configured to exist. Therefore, when cutting and using to Xmm which is a predetermined dimension, it can cut | disconnect and use by the easy cutting part in the position of distance dimension Xmm from the other edge part. That is, according to the configuration of the present invention, the dimension adjusting member can be cut from one of the end portions with a predetermined dimension Xmm by the easy-to-cut portion, and the cutting work is facilitated.
Moreover, since the present invention does not employ a configuration including the first wiring insertion member and the second wiring insertion member as in the invention described in Patent Document 1 described above, the invention is described in Patent Document 1. Compared with this invention, costs (costs such as material costs and inventory management costs) can be reduced.
Note that the present invention is not configured such that the second wiring insertion member is detachably fitted into the first insertion member as in the invention described in Patent Document 1 described above. No step is generated at the boundary between the wiring insertion member and the second wiring insertion member. Therefore, according to the present invention, the appearance does not deteriorate due to the step, and it is not necessary to perform post-processing on the step in order to eliminate the poor appearance.

  Further, it is preferable that an adjustment region is provided in at least a part of the total length, and a distance dimension Xmm from the end portion exists in the adjustment region.

  Furthermore, in the said adjustment area | region, the said cutting | disconnection easy part may be formed in the ratio larger than another part.

  In the dimension adjusting member of the present invention, the total length of the adjustment area is Ymm, the distance dimension from the one end to the adjustment area is Zmm, and the distance dimension from the other end to the adjustment area is L−. In the case of Y−Zmm and Z <L−Y−Z, it is desirable that the Xmm can be adjusted to a distance dimension of at least L−Y−Z <X <Y + Z.

Further, in the dimension adjusting member of the present invention, the easy-to-cut parts having a plurality of same width dimensions Amm are formed in the adjustment area with a predetermined spacing dimension Bmm, and B <A and the following ( It is desirable that the distance dimension satisfying the expression 1) is satisfied.
Z + N (A + B) + B ≦ L−Y−Z ≦ Z + N (A + B) + A, (N (integer) ≧ 0) (Formula 1)

  Further, the dimension adjusting member is formed in a U-shaped cross section having at least an upper surface and a side surface formed by bending and extending a side edge of the upper surface downward, and is laid on a foundation floor surface, A wiring space or a piping space may be formed below the upper surface.

  Furthermore, the structure which the said easy cutting part consists of the notch or opening formed in the said side surface may be sufficient.

  The easy-to-cut part may be formed thinner than other parts.

  According to the present invention, it is possible to provide a dimension adjusting member that is inexpensive and can be easily cut into a predetermined dimension.

  Hereinafter, the dimension adjustment member of embodiment (1st Embodiment, 2nd Embodiment) of this invention is demonstrated along drawing. In addition, this invention is not limited to embodiment shown below.

<First Embodiment>
A dimension adjusting member according to a first embodiment of the present invention will be described with reference to the drawings.
First, the structure of the dimension adjustment member of 1st Embodiment is demonstrated, referring FIGS. 1-3.
Here, FIGS. 1 and 2 are schematic views for explaining the configuration of the dimension adjusting member of the first embodiment. FIG. 3 is a schematic view for explaining the dimensional relationship of each component of the dimension adjusting member according to the first embodiment of the present invention.
In the first embodiment, as an example, the case where the dimension adjusting member is used for a double floor that forms a wiring space under the floor is shown.

  As shown in FIGS. 1 and 2, the dimension adjusting member 100 of the first embodiment is a flat plate-shaped upper surface portion 110 having a substantially rectangular shape in plan view, and a flat plate shape in which both side ends of the upper surface portion 110 are bent and extended downward. The side surface portion 120 is formed in a U-shaped cross section. Further, the side portion 120 is formed with easy-to-cut portions 121 made of notches at regular intervals. In the example illustrated, the easy-to-cut portion 121 is formed in a shape in which the lower end of the side surface portion 120 is cut out into a rectangular shape with a certain interval.

The dimension adjusting member 100 is formed so as to have the following positional relationship.
Specifically, as shown in FIG. 3, the dimension adjusting member 100 is formed such that the distance dimension of the entire length (distance dimension in the longitudinal direction) is “Lmm (L> 0 mm)”. Further, in the dimension adjusting member 100, an area between the easy-to-cut parts 121 located on both outer sides (left and right sides in the drawing) is an adjustment area 123. The adjustment area (dimension adjustment area) 123 has a distance dimension (distance dimension in the longitudinal direction) of “Ymm (L>Y> 0 mm)”. Further, the distance dimension (distance dimension in the longitudinal direction) from one end of the dimension adjusting member 100 to the adjustment area 123 is “Zmm”, and the distance dimension from the other end to the adjustment area 123 (distance dimension in the longitudinal direction). Is "LY-Zmm". Further, “Zmm” that is the distance dimension from one end of the dimension adjusting member 100 to the adjustment area 123 is shorter than “LY-Zmm” that is the distance dimension from the other end to the adjustment area 123. (Z <(LYZ)).

  A plurality of easy-to-cut portions 121 having a width Amm are provided in the adjustment region 123 with a predetermined distance Bmm (eight in the illustrated example). In the present embodiment, portions other than the easy-to-cut portion 121 in the adjustment region 123 are referred to as non-easy-to-cut portions 122 because cutting is not easier than the easy-to-cut portion 121.

  Further, the width Amm of the easy-to-cut portion 121 is formed longer than the width Bmm of the non-cutable portion 122 (A> B). Further, when the dimension adjustment member 100 is rotated 180 degrees in the horizontal direction, the easy-to-cut part 121 after rotation is positioned in the part of the non-stable cutting part 122 before rotation. That is, as shown in FIG. 3A, when the non-cutting easy part 122 is positioned at a distance X from one end of the dimension adjusting member 100, the easy cutting part 121 is always at a distance X from the other end. Is formed to be positioned. In the first embodiment, since A> B, the relationship between the distance X ′ from the one end to the easy-to-cut portion 121 and the component at the distance X ′ from the other end is from the one end. When the easy-to-cut part 121 exists at the distance X ′, a part where the easy-to-cut part 121 is formed also appears at the distance X ′ from the other end.

And the dimension adjustment member 100 of 1st Embodiment becomes a structure which can respond | correspond all if it is a dimension adjustment of the range of Z <= X <= LZ, when Z <= B.
On the other hand, in the case of B ≦ Z, it is possible to cope with the dimension adjustment of “B ≦ X ≦ L−Z” by cutting the easy-to-cut portion 121 located on both sides of a certain non-cutable portion 122. That is, the Bmm dimension adjusting member 100 can be configured by cutting the easy-to-cut portions 121 located in contact with both sides of a certain non-cutable portion 122. In addition, the dimension adjustment member 100 of L-Zmm can be comprised by cut | disconnecting the cutting easy part 121 in the position of Zmm from one end.

Moreover, the dimension adjustment member 100 of 1st Embodiment satisfy | fills the relational expression of the following (Formula 1), when the width Amm of the cutting easy part 121 and the width Bmm of the cutting non-easy part 122 are constant and B <A. It is formed to have a distance dimension. The following N is an integer.
Z + N (A + B) + B ≦ L−Y−Z ≦ Z + N (A + B) + A, (N ≧ 0) (Formula 1)

  The dimension adjusting member 100 is formed with a dimension satisfying the above (Formula 1), so that in the adjusting region 123, when the non-cutting easy portion 122 is formed at a distance X from one end, the other end The easy-to-cut part 121 is formed at the position of the distance X from the distance. Hereinafter, the reason why the dimension adjusting member 100 is configured to satisfy the above relational expression will be described with reference to FIG.

Here, FIG. 4 is a schematic diagram for explaining the range of the distance dimension of the dimension adjusting member of the first embodiment of the present invention, and (a) is a schematic diagram showing the overall dimension of the dimension adjusting member. (B) demonstrates the relationship between the structure of the adjustment area | region of the distance X from one end, and the structure of the adjustment area | region of the distance X from the other end in case the distance dimension from the both ends of a dimension adjustment member is the same. For adjusting the distance X from one end when (c) to (e) are different from the distance from the other end to the adjustment region in the distance from the other end to the adjustment region. It is a schematic diagram for demonstrating the relationship between the structure of an area | region, and the structure of the adjustment area | region of distance X from the other end.
4 (c) shows a case where the difference δ between the distance dimension from one end of the dimension adjusting member 100 to the adjustment area 123 and the distance dimension from the other end to the adjustment area 123 is B from one end. It is a schematic diagram for demonstrating the relationship between the structure of the adjustment area | region of the distance X, and the structure of the adjustment area | region of the distance X from the other end. FIG. 4D is a schematic diagram for explaining the configuration of the adjustment region 123 at a distance X from one end and the configuration of the adjustment region 123 at a distance X from the other end when the difference δ is A. FIG. FIG. 4E illustrates the configuration of the adjustment region 123 at a distance X from one end and the configuration of the adjustment region 123 at a distance X from the other end when the difference δ is “(A + B) + A”. It is a schematic diagram for.
Further, the example shown in FIG. 4B does not satisfy the above (Equation 1), but for the sake of convenience of explanation, the same reference numerals as those in the first embodiment are attached.

  As described above, in the dimension adjustment member 100 of the first embodiment, the distance dimension from one end to the adjustment area 123 is “Zmm”, and the distance dimension from the other end to the adjustment area 123 is “L−Y−Zmm”. "It has become. Further, “L−Y−Zmm” is larger than “Zmm” (Z <(LY−Z)). Then, “L−Y−Zmm” can be represented by “Z + δ” as shown in FIG. 4A when the difference δ from “Zmm” is used. The difference δ is “L−Y−2Z” (δ = L−Y−2Z).

  Then, as shown in FIG. 4B, when there is no difference δ (when δ = 0), the configuration of the adjustment region 123 is located at a distance X from one end, and is located at a distance X from the other end. The configuration of the adjustment area 123 is the same. That is, when the non-easy cutting portion 122 is formed at a position X from one end, the non-easy cutting portion 122 is also formed at a position X from the other end. Thus, when there is no difference δ (when δ = 0), when the non-cleavable portion 122 is located at a distance X from one end, the easy-to-cut portion 121 is located at a distance X from the other end. Not like that. Therefore, in the first embodiment, a configuration in which the difference δ is provided is adopted.

By the way, if it forms in the structure which has said difference (delta), when the cutting | disconnection non-easy part 122 is formed in the position of the distance X from one end, the cutting easy part 121 is formed in the position of the distance X from the other end. Since the portion appears, it is possible to achieve an effect that the range in which the dimension can be adjusted is larger than that in the configuration without the difference δ.
However, the inventor of the present application has studied the size range of the difference δ in order to increase the size adjustable range as much as possible to cope with various distance dimensions. Specifically, the inventors of the present application set the difference δ as “δ = B” as shown in FIG. 4C and “δ = A” as shown in FIG. And examined the case.

As shown in FIG. 4C, when “δ = B”, the boundary portion with the easy-to-cut portion 121 (for example, the portion indicated by reference numeral 122a in the figure) is located at a distance X from one end. When the non-cutting easy part 122 is located, the easy cutting part 121 is formed at a position of a distance X from the other end.
Further, as shown in FIG. 4D, when “δ = A”, the distance X from one end including the boundary portion with the easy-to-cut portion 121 (for example, the portion indicated by reference numeral 122a in the drawing) is obtained. When the non-easy cutting part 122 is located at the position, the easy cutting part 121 is formed at a position of a distance X from the other end.

  Then, the inventor of the present application sets the dimension so that δ becomes “B ≦ δ ≦ A” from the relationship of FIG. 4C and FIG. It has been found that when the non-cleavable part 122 is located at the position, the easy-to-cut part 121 is always located at a distance X from the other end. That is, by setting δ to “B ≦ δ ≦ A”, even when the above boundary portion (portion 122a) is a distance X from one end, the easy-to-cut portion 121 is located at a distance X from the other end. Will be formed.

Furthermore, the inventor of the present application has found that the same relationship as described above is established even when δ is increased in units of “A + B” with respect to “B ≦ δ ≦ A”. For example, as shown in FIG. 4E, even when “δ = (A + B) + A” is set, similarly to the case where “δ = A”, the non-easy cutting portion 122 is located at a distance X from one end. Is located at a distance X from the other end.
Therefore, if “A + B” is added to “B ≦ δ ≦ A” to form “(A + B) + B ≦ δ ≦ (A + B) + A”, the dimension adjustment member 100 is formed in the adjustment region 123. When the non-cleavable portion 122 is located at a distance X from one end, the easy-to-cut portion 121 is formed at a distance X from the other end.
In the example shown in FIG. 4E, the region other than the adjustment region 123 (both ends of the dimension adjustment member 100) has the other end when the non-easy cutting portion 122 is located at a distance X from one end. The portion where the easy-to-cut portion 121 is formed at the position of the distance X is not established.

The relationship when δ is increased in units of “A + B” with respect to “B ≦ δ ≦ A” can be expressed by the following (Formula 2).
B + N (A + B) ≦ δ ≦ A + N (A + B), (N (integer) ≧ 0) (Formula 2)

That is, by forming the dimension adjusting member 100 so as to satisfy the above (Formula 2), when the cutting non-easy part 122 is located at the position of the distance X from one end of the adjustment region 123, the dimension adjusting member 100 starts from the other end. The easy-to-cut portion 121 is formed at the position of the distance X.
The above-mentioned “B ≦ δ ≦ A” indicates the case of “N = 0” in the above (Formula 2). The above-mentioned “(A + B) + B ≦ δ ≦ (A + B) + A” indicates the case of “N = 1” in the above (Expression 2).

Further, as shown in FIG. 4A, since “δ = L−Y−2Z”, the above (Formula 2) can be expressed by the following (Formula 3).
N (A + B) + B ≦ L−Y−2Z ≦ N (A + B) + A, (N (integer) ≧ 0) (Equation 3)
Then, by modifying (Equation 3) below, “Z + N (A + B) + B ≦ L−Y−Z ≦ Z + N (A + B) + A, (N ≧ 0)” shown in (Equation 1) is derived. .
In this way, when the dimension adjusting member 100 is formed with a size that satisfies the above (Formula 1), in the adjustment region 123, when the cutting non-easy portion 122 is formed at the position of the distance X from one end, An easy-to-cut portion 121 is formed at a distance X from the other end. As a result, according to the first embodiment, the range in which the dimension can be adjusted is increased, and the dimension adjusting member 100 that can be used at various construction sites is provided.
In addition, when it considers that it is not easy to cut | disconnect some parts (the boundary part (for example, the part of the code | symbol 122a in a figure) with the easy-to-cut part 121) in the easy-to-cut part 121, it considers the non-easy part 122, (Equation 4).
Z + N (A + B) + B <L−Y−Z <Z + N (A + B) + A, (N ≧ 0) (Formula 4)

Next, the structure of the double floor 200 in which the dimension adjustment member 100 of 1st Embodiment is used and the usage example of the dimension adjustment member 100 are demonstrated, referring FIGS.
Here, FIG. 5 is a schematic diagram for explaining the double floor of the first embodiment. Drawing 6 is a mimetic diagram showing the process of constructing the double floor of a 1st embodiment. FIG. 7 is an explanatory perspective view showing the usage state of the double floor, the border portion, and the dimension adjusting member of the first embodiment.

  As shown in the figure, the double floor 200 includes a support part 210 disposed on the foundation floor 300 of the building and a floor part 220 supported by the support part 210. In the double floor 200, a space 240 (see FIG. 5B) is formed between the foundation floor 300 and the floor portion 220 by the support portion 210, and wiring or piping is laid in the space 240. It is possible.

  In addition, the floor portion 220 has a substantially rectangular upper surface portion 221 in the plan view, projections 222 (see FIG. 5A) that are formed near the four corners of the upper surface portion 221 and project downward, and the upper surface portion 221. The drooping piece 223 (see FIG. 5B) is formed at substantially the central part of the four sides and is bent and extended downward. The drooping piece 223 greatly improves the strength of the floor portion 220.

In addition, the support part 210 includes four pillar-shaped block bodies made of odd-shaped pentagons obtained by cutting one corner of a square in plan view, and a thin connecting part 216 at the top part and the lower end of the side face (see FIGS. 5A and 5B). It is formed by connecting with.
Specifically, the support part 210 forms a columnar part 211 that forms a top face 212 (see FIG. 5A) that is octagonal in plan view and has a side face 213, and a columnar part 211. A sound absorbing material 230 made of a nonwoven fabric or a rubber material pasted on the top surface 212, and a belt-like portion 217 that connects the lower ends of the four adjacent struts 211 in a cross shape. In this embodiment, as shown in FIG. 5A, twelve support columns 211 are connected by a belt-like portion 217 to form one support unit. In addition, a band-shaped portion 217 protrudes further outward than the column portion 211 located on the outermost side of the support unit, and the tip of the protruding band-shaped portion 217 can be connected to another support unit. It has become.

  Further, the corners of the four floor portions 220 are collectively placed on the top surface 212 of the column portion 211. Further, on the top surface 212 of the support column 211, a hole 214 into which the projection 222 of the floor 220 is inserted through the sound absorbing material 230 and a hanging piece 223 (see FIG. 5B) of the floor 220 are the sound absorbing material. A slit portion 215 (a gap between the block bodies) to be engaged through the cutting portion 231 of 230 is formed continuously from the top surface 212 to the vicinity of the lower end of the side surface 213.

  Then, as shown in FIG. 6, the double floor 200 is formed by connecting a plurality of support portions 210 having the above-described configuration and laying them on the foundation floor 300 and placing the floor portion 220 on the top surface 212 of the support column 211. Complete.

  By the way, when the double floor 200 is laid on the foundation floor 300, the shape and size of the foundation floor 300 are not necessarily matched to the support unit, and are adjusted by the wall 301 at the place of laying. Necessity comes out.

  Specifically, as shown in FIG. 7, the place where the mass wiring 500 is not provided from the wall 301 can be adjusted by laying the border member 400 and slidably laying the border cover 401 thereon. Further, in a place where a large amount of wiring 500 is provided from the wall 301, a block body of a part of the column portions 211 is cut by a thin connecting portion 216, and the dimension adjusting member 100 is adjusted according to the distance X from the wall 301 to the column portions 211. This can be dealt with by cutting and adjusting the length and laying (cutting at the cutting line 600 in the figure). At this time, as described above with reference to FIG. 3, the distance X from one end and the distance X from the other end are always configured so that the easy-to-cut portion 121 is present, and therefore the dimension X is necessary. It is always possible to cut with the easy cutting part 121.

As described above, by using the dimension adjusting member 100 of the first embodiment, the easy-to-cut portion 121 can always cut the distance X from the wall 301 regardless of the dimension, and the workability of the cutting can be improved. And workability is improved.
Further, according to the first embodiment, since only one type of dimension adjusting member 100 needs to be prepared, it leads to a comprehensive cost reduction such as member management and inventory management.

Second Embodiment
Next, the dimension adjustment member of 2nd Embodiment of this invention is demonstrated using FIG. Although the dimension adjustment member of 2nd Embodiment is used as a plate member for ceiling decorations, the principle for adjusting a dimension is the same as 1st Embodiment. Therefore, below, the detail of a location different from 1st Embodiment is demonstrated.
Here, FIG. 8 is a figure for demonstrating the dimension adjustment member of 2nd Embodiment of this invention.

  As shown in FIG. 8, the dimension adjusting member 700 of the second embodiment has a substantially rectangular shape in plan view and an easy-to-cut portion 701 formed on the back surface in a concave shape in the width direction, and easier to cut than the easy-to-cut portion 701.

Alternatively, as shown in FIG. 9B, a plurality of thin portions are provided on the side surface portion 120 at intervals similar to the cutouts of the first embodiment to form the easy-to-cut portion 802. The present invention may be anything as long as it can distinguish between a portion that can be easily cut and a normal portion. Further, the opening need not be a square opening, and may be an appropriate shape such as a circle or an ellipse. Further, the thin wall portion does not need to be outside the side surface, and may be inside the side surface. Further, it may not be from the upper end to the lower end of the side surface, and may be a part. In addition, a thin wall portion is provided on the back surface of the upper surface portion 110, or an opening is provided on the upper surface portion 110 if not used as a double floor. Furthermore, an opening or notch and a thin part are provided at the same position, and an easy-to-cut part is formed by the opening and the thin part, or an easy-to-cut part is formed by the notch and the thin part. Needless to say, a single dimension adjusting member may be provided with a plurality of various easy-to-cut parts such as an easy-to-cut part by notch, an easy-to-cut part by opening, and an easy-to-cut part by thin part.

  Moreover, although the dimension adjustment member 100 of said 1st Embodiment showed the example which can be adjusted in the range of Z <= X <= LZ in the case of Z <= B, this invention has at least Z <LY. In the case of -Z, it is preferable if it can be adjusted to all dimensions of L-Y-Z <X <Y + Z, and even if it is not included in this range, it has dimensions that are easy to cut and non-easy to cut. Any adjustment is included in the present invention.

  In addition, the arrangement of the easy-to-cut sections 121 of the first embodiment is not limited to the first embodiment, and the distance dimension “Ymm” of the adjustment region 123 may be a narrow range. One dimension adjustment member 100 does not need to be one adjustment area, and there may be a plurality of adjustment areas 123.

  Moreover, in said 1st Embodiment, although the notch which forms the cutting | disconnection easy part 121 is formed in the both side surface parts 120, the need does not necessarily exist. The notch of the side surface portion 120 is shifted so that the normal portion needs to be cut off from the upper surface portion 110 and the both side surface portions 120, whereas the easy cutting portion can be cut from the upper surface portion 120 and one side surface portion 120. It is good also as a structure.

  In the first embodiment, in the dimension adjustment member 100, a region “Zmm” is formed between one end and the adjustment region 123, and “L−Y−Zmm” is formed between the other end and the adjustment region 123. However, the present invention is not limited to this. The “Zmm region” or the “LY-Zmm region” may not be formed. Moreover, it is good also as a structure which provides a notch in the at least 1 edge part of the dimension adjustment member 100 side part 120. FIG.
