Abstract
Description
本発明は、溶接構造物に関する。 The present invention relates to a welded structure.
例えば車両において、パイプと取付部材との接合など、レーザ溶接による部品同士の接合が施されている溶接構造物が知られている。例えば、特許文献１には、Ｃ字状の溶接線を有する溶接施工部が形成された溶接構造物が開示されている。 For example, in a vehicle, a welded structure is known in which parts are joined to each other by laser welding, such as joining a pipe and an attachment member. For example, Patent Document 1 discloses a welded structure in which a welding portion having a C-shaped weld line is formed.
ところが、レーザ溶接による溶接線の端部（溶接の始点及び終点）は、ポロシティ（空洞）が発生しやすい等の理由により、安定して良好な溶接強度が得られにくく、応力が溶接線の端部に集中する場合、溶接施工部のはがれが発生する問題があった。 However, the end of the weld line by laser welding (starting point and end point of welding) is difficult to obtain a stable and stable weld strength due to the fact that porosity (cavity) is likely to occur, and the stress is at the end of the weld line. When concentrated on the part, there was a problem that peeling of the welded part occurred.
本発明は、溶接施工部のはがれが生じにくい溶接構造物の提供を目的としている。 An object of the present invention is to provide a welded structure in which peeling of a welded part is less likely to occur.
本発明の一側面は、溶接構造物であって、第１の部材と、第２の部材と、を備える。第２の部材は、第１の部材とレーザ溶接によって接合され、少なくとも１本の溶接線を有する溶接施工部が形成されている。溶接線の各端部は、溶接施工部を最短の長さで囲む１本の外周線から離間して配置される。 One aspect of the present invention is a welded structure, and includes a first member and a second member. The second member is joined to the first member by laser welding, and a welding construction portion having at least one weld line is formed. Each end portion of the weld line is arranged apart from one outer peripheral line that surrounds the welding construction portion with the shortest length.
このような構成によれば、溶接線の各端部が溶接施工部における最も外側の位置（外周線に隣接する位置）よりも内側に配置され、溶接施工部に荷重が加わった際に各端部よりも先に溶接線における端部以外の部分に応力がかかりやすくなるため、各端部への応力の集中が抑制される。よって、溶接施工部のはがれが生じにくい溶接構造物の提供が可能となる。 According to such a configuration, each end of the weld line is arranged on the inner side of the outermost position (position adjacent to the outer peripheral line) in the weld construction part, and each end when a load is applied to the weld construction part. Since stress is easily applied to portions other than the end portion of the weld line before the portion, concentration of stress on each end portion is suppressed. Therefore, it is possible to provide a welded structure in which the weld construction part is not easily peeled off.
上記構成において、溶接線の各端部は、溶接施工部が有する少なくとも１本の溶接線に３６０度囲まれていてもよい。このような構成によれば、溶接施工部にどの方向から荷重が加わった場合にも、各端部よりも先に溶接線における端部以外の部分に応力がかかるため、各端部に応力が集中することを抑制することができる。 In the above configuration, each end portion of the weld line may be surrounded by 360 degrees with at least one weld line included in the welding portion. According to such a configuration, even when a load is applied to the welded portion from any direction, stress is applied to portions other than the end portion of the weld line before each end portion, so that stress is applied to each end portion. Concentration can be suppressed.
上記構成において、溶接線の各端部である第１の端部及び第２の端部は、第１の端部及び第２の端部を有する溶接線に３６０度囲まれていてもよい。このような構成によれば、１本の溶接線によっても、第１の端部及び第２の端部に応力が集中することを抑制することができる。 The said structure WHEREIN: The 1st end part and 2nd end part which are each edge part of a weld line may be enclosed 360 degree | times with the weld line which has a 1st end part and a 2nd end part. According to such a structure, it can suppress that stress concentrates on a 1st edge part and a 2nd edge part also with one welding line.
上記構成において、溶接線は、端部同士の間に開口部が形成されたＣ字状であってもよい。このような構成によれば、溶接線が閉じた形状に形成される場合と比較して、溶接線により囲まれた部分に孔が空いてしまうことを防ぐことができる。 In the above configuration, the weld line may have a C shape in which an opening is formed between the ends. According to such a configuration, it is possible to prevent a hole from being formed in a portion surrounded by the weld line, as compared with a case where the weld line is formed in a closed shape.
上記構成において、少なくとも一部が外周線に沿って配置された溶接線の開口部が、外周線に面していなくてもよい。このような構成によれば、少なくとも一部が外周線に沿って（溶接施工部における最も外側の位置に）配置された溶接線の各端部が、外周線に隣接する位置に配置されない。よって、溶接施工部に１本のみ形成された場合には端部が外周線に隣接する位置に配置される形状の溶接線であっても、複数本の配置により端部が外周線に隣接しないようにすることができる。 The said structure WHEREIN: The opening part of the welding line at least one part arrange | positioned along an outer periphery line does not need to face the outer periphery line. According to such a structure, each edge part of the welding line arrange | positioned along an outer periphery line at least one part (at the outermost position in a welding construction part) is not arrange | positioned in the position adjacent to an outer periphery line. Therefore, when only one weld is formed in the welded portion, even if the end is located at a position adjacent to the outer peripheral line, the end is not adjacent to the outer peripheral line due to the plurality of arrangements. Can be.
以下、本発明の例示的な実施形態について図面を参照しながら説明する。
［１．第１実施形態］
［１−１．構成］
図１に示す第１実施形態のインパネリインフォースメント１０は、車両を構成する溶接構造物であり、インストルメントパネル内において車両幅方向（車両左右方向）に沿って、図示しない運転席側ピラーと助手席側ピラーとの間に配設されている。なお、車両左右方向における左右とは、車両後方から車両前方を見た際の左右のことをいい、図１に示すインパネリインフォースメント１０では、左端部１１（運転席側）が左側となり、右端部１２（助手席側）が右側となる。インパネリインフォースメント１０は、大径パイプ２と、小径パイプ３と、ブレースブラケット４と、を備える。
Hereinafter, exemplary embodiments of the present invention will be described with reference to the drawings.
[1. First Embodiment]
[1-1. Constitution]
An instrument panel reinforcement 10 according to the first embodiment shown in FIG. 1 is a welded structure that constitutes a vehicle. A driver side pillar and an assistant (not shown) are arranged along the vehicle width direction (the vehicle left-right direction) in the instrument panel. It is arranged between the seat side pillars. The left and right in the vehicle left-right direction means the left and right when the vehicle front is viewed from the rear of the vehicle. In the instrument panel reinforcement 10 shown in FIG. 1, the left end portion 11 (driver's seat side) is the left side, and the right end portion 12 (passenger side) is on the right. The instrument panel reinforcement 10 includes a large-diameter pipe 2, a small-diameter pipe 3, and a brace bracket 4.
大径パイプ２は、インパネリインフォースメント１０の左端部１１を含む運転席側部分を構成している。大径パイプ２は、ブラケット等の部材を介して、ステアリングコラム（図示せず）を支持している。 The large-diameter pipe 2 constitutes a driver seat side portion including the left end portion 11 of the instrument panel reinforcement 10. The large diameter pipe 2 supports a steering column (not shown) via a member such as a bracket.
小径パイプ３は、インパネリインフォースメント１０の右端部１２を含む運転席とは反対側（助手席側）の部分を構成している。小径パイプ３の外径は、大径パイプ２の外径よりも小さい。また、小径パイプ３の厚み（板厚）は、大径パイプ２の厚みよりも薄い。小径パイプ３は、大径パイプ２と溶接等により連結されている。 The small-diameter pipe 3 constitutes a portion on the side opposite to the driver's seat (passenger seat side) including the right end portion 12 of the instrument panel reinforcement 10. The outer diameter of the small diameter pipe 3 is smaller than the outer diameter of the large diameter pipe 2. Further, the thickness (plate thickness) of the small diameter pipe 3 is smaller than the thickness of the large diameter pipe 2. The small diameter pipe 3 is connected to the large diameter pipe 2 by welding or the like.
ブレースブラケット４は、インパネリインフォースメント１０の車両下方側に配設されているフロアブレース（図示せず）を大径パイプ２に固定する鋼板状の部材である。図２に示すように、ブレースブラケット４は、Ｕ字状に折り曲げられた形状の本体部４０と、本体部４０から延設されたフランジ部４１と、を備える。本体部４０には、締結孔４２が形成されている。フランジ部４１は、ブレースブラケット４の端部に形成され、大径パイプ２と当接する。フランジ部４１は、大径パイプ２とレーザ溶接によって接合され、接合された箇所が、後述する溶接施工部６となる。本体部４０は、締結孔４２に挿通されたボルト５によりフロアブレースの上端部に締結される。このようにして、大径パイプ２にフロアブレースが固定される。なお、フロアブレースの下端部は車体フロア（図示せず）に固定されている。 The brace bracket 4 is a steel plate-like member that fixes a floor brace (not shown) disposed on the vehicle lower side of the instrument panel reinforcement 10 to the large-diameter pipe 2. As shown in FIG. 2, the brace bracket 4 includes a main body 40 that is bent into a U-shape and a flange 41 that extends from the main body 40. A fastening hole 42 is formed in the main body 40. The flange portion 41 is formed at an end portion of the brace bracket 4 and abuts on the large-diameter pipe 2. The flange portion 41 is joined to the large-diameter pipe 2 by laser welding, and the joined portion becomes a welding construction portion 6 to be described later. The main body 40 is fastened to the upper end of the floor brace by the bolt 5 inserted through the fastening hole 42. In this way, the floor brace is fixed to the large diameter pipe 2. The lower end of the floor brace is fixed to a vehicle body floor (not shown).
次に、レーザ溶接によって形成される溶接施工部６について具体的に説明する。
図３に示すように、溶接施工部６は、レーザ溶接によって、フランジ部４１に溶接の軌跡である溶接線６１が施されることにより形成される。本実施形態では、溶接施工部６は、複数（この例では４本）の溶接線６１を有する。各溶接線６１は、溶接の始点及び終点である２つの溶接端部６２同士の間に開口部６１０が形成されたＣ字状の形状である。各溶接線６１は、２つの円弧６１１を有する。
Next, the welding construction part 6 formed by laser welding will be specifically described.
As shown in FIG. 3, the welding execution part 6 is formed by giving the welding line 61 which is a locus of welding to the flange part 41 by laser welding. In this embodiment, the welding construction part 6 has a plurality (four in this example) of welding lines 61. Each weld line 61 has a C-shaped shape in which an opening 610 is formed between two weld end portions 62 that are a start point and an end point of welding. Each weld line 61 has two arcs 611.
外周線６３は、溶接施工部６を最短の長さで囲む１本の仮想線である。外周線６３は、溶接施工部６が有するすべて（この例では４本）の溶接線６１を包含するようにして描かれる。本実施形態では、各溶接線６１の一部が外周線６３に沿って（溶接施工部６における最も外側の位置に）配置されており、各溶接線６１の開口部６１０が、外周線６３に面しないよう配置されている。その結果、各溶接端部６２は、外周線６３から離間して配置されている。なお、ここでいう「離間して配置」とは、溶接端部６２が溶接施工部６における最も外側の位置（外周線６３に隣接する位置）よりも内側に配置されることを意味する。 The outer peripheral line 63 is one imaginary line that surrounds the welding construction portion 6 with the shortest length. The outer peripheral line 63 is drawn so as to include all (four in this example) weld lines 61 included in the welding portion 6. In the present embodiment, a part of each welding line 61 is arranged along the outer circumferential line 63 (at the outermost position in the welding portion 6), and the opening 610 of each welding line 61 is connected to the outer circumferential line 63. It is arranged not to face. As a result, each weld end 62 is disposed away from the outer circumferential line 63. Here, “disposed apart” means that the weld end portion 62 is disposed on the inner side of the outermost position (position adjacent to the outer circumferential line 63) in the welding portion 6.
［１−２．効果］
以上詳述した第１実施形態によれば、以下の効果が得られる。
（１ａ）ブレースブラケット４は、大径パイプ２とレーザ溶接によって接合される。ブレースブラケット４には、４本の溶接線６１を有する溶接施工部６が形成されている。溶接線６１の各溶接端部６２は、溶接施工部６を最短の長さで囲む１本の外周線６３から離間して配置される。
[1-2. effect]
According to the first embodiment described in detail above, the following effects can be obtained.
(1a) The brace bracket 4 is joined to the large-diameter pipe 2 by laser welding. The brace bracket 4 is formed with a welding portion 6 having four welding lines 61. Each weld end 62 of the weld line 61 is disposed away from one outer peripheral line 63 that surrounds the welding portion 6 with the shortest length.
このような構成によれば、溶接線６１の各溶接端部６２が溶接施工部６における最も外側の位置（外周線６３に隣接する位置）よりも内側に配置される。したがって、例えば車両の衝突などの衝撃により溶接施工部６に荷重が加わった際に、溶接端部６２よりも先に溶接線６１における溶接端部６２以外の部分に応力がかかりやすくなるため、溶接端部６２への応力の集中が抑制される。よって、溶接施工部６のはがれが生じにくいインパネリインフォースメント１０の提供が可能となる。 According to such a configuration, each welding end portion 62 of the welding line 61 is arranged on the inner side of the outermost position (position adjacent to the outer circumferential line 63) in the welding execution portion 6. Therefore, for example, when a load is applied to the welding portion 6 due to an impact such as a collision of a vehicle, stress is easily applied to a portion other than the welding end portion 62 in the welding line 61 before the welding end portion 62. Concentration of stress on the end 62 is suppressed. Therefore, it is possible to provide the instrument panel reinforcement 10 in which the welding construction part 6 is unlikely to peel off.
すなわち、例えば、図５に示すように、溶接端部８２が外周線８３と隣接する位置に配置された溶接施工部８では、開口部８１０の方向（方向ａ）に荷重が加わると、溶接端部８２に応力が集中しやすくなる。溶接端部８２は、溶接線８１における溶接端部８２以外の部分と比較して、溶接加工の性能上溶接強度（許容応力）が劣るため、荷重の大きさによっては、溶接施工部６のはがれが発生する場合がある。 That is, for example, as shown in FIG. 5, in the welding portion 8 in which the weld end portion 82 is disposed at a position adjacent to the outer circumferential line 83, when a load is applied in the direction of the opening 810 (direction a), Stress is easily concentrated on the portion 82. The weld end portion 82 is inferior in weld strength (allowable stress) in terms of welding performance as compared with the portions other than the weld end portion 82 in the weld line 81. Therefore, depending on the magnitude of the load, the welded portion 6 peels off. May occur.
これに対し、第１実施形態の溶接施工部６では、４つの溶接線６１のそれぞれの開口部６１０が外周線６３に面しておらず、各溶接端部６２が、外周線６３に隣接する位置よりも内側に配置されている。その結果、溶接端部６２への応力の集中を抑制することができる。 On the other hand, in the welding execution part 6 of 1st Embodiment, each opening part 610 of the four welding lines 61 does not face the outer periphery line 63, and each welding end part 62 adjoins the outer periphery line 63. FIG. It is arranged inside the position. As a result, concentration of stress on the weld end 62 can be suppressed.
（１ｂ）溶接線６１は、溶接端部６２同士の間に開口部６１０が形成されたＣ字状の形状を有する。このような構成によれば、溶接線が閉じた形状に形成される場合と比較して、溶接線６１により囲まれた部分に孔が空いてしまうことを防ぐことができる。 (1b) The weld line 61 has a C-shape in which an opening 610 is formed between the weld ends 62. According to such a configuration, it is possible to prevent a hole from being formed in a portion surrounded by the weld line 61 as compared with a case where the weld line is formed in a closed shape.
（１ｃ）溶接線６１の開口部６１０が、外周線６３に面していない。このような構成によれば、溶接線６１の各溶接端部６２が、外周線６３に隣接する位置に配置されない。よって、溶接施工部に１本のみ形成された場合には溶接端部が外周線に隣接する位置に配置される形状（単純なＣ字状）の溶接線であっても、複数本の配置により溶接端部が外周線に隣接しないようにすることができる。 (1c) The opening 610 of the weld line 61 does not face the outer peripheral line 63. According to such a configuration, each weld end 62 of the weld line 61 is not disposed at a position adjacent to the outer peripheral line 63. Therefore, when only one weld is formed in the weld construction part, even if it is a weld line having a shape (simple C-shape) where the weld end is located adjacent to the outer circumference line, It is possible to prevent the weld end from being adjacent to the outer circumference.
［２．第２実施形態］
図４に示す第２実施形態の溶接施工部７は、第１実施形態の溶接線６１とは形状が異なる１本の溶接線７１を有する。つまり、第２実施形態は、４本の溶接線６１を有する溶接施工部６に代えて、１本の溶接線７１を有する溶接施工部７が形成されている点で、第１実施形態と異なる。その他、基本的な構成は第１実施形態と同様であり、第１実施形態と共通する構成については、同一符号を用いて説明を省略する。
[2. Second Embodiment]
The welding execution part 7 of 2nd Embodiment shown in FIG. 4 has the welding line 71 from which the shape differs from the welding line 61 of 1st Embodiment. That is, the second embodiment is different from the first embodiment in that a welding construction portion 7 having one welding line 71 is formed instead of the welding construction portion 6 having four welding lines 61. . In addition, the basic configuration is the same as that of the first embodiment, and the description of the same configuration as that of the first embodiment is omitted by using the same reference numerals.
溶接線７１は、第１実施形態の溶接線６１と同様、レーザ溶接によって形成され、円弧７１１を含むＣ字状の形状を有しているが、溶接の始点及び終点付近における形状が異なる。すなわち、溶接線６１の各溶接端部６２は、円弧６１１から延長された直線部分の末端であるのに対し、溶接線７１の各溶接端部７２は、開口部７１０から更に円弧７１１の内部側に回り込むように描かれる円弧７１２の末端である。このため、各溶接端部７２は、溶接施工部７を最短の長さで囲む１本の仮想線である外周線７３から離間して配置される。特に、本実施形態では、各溶接端部７２が、溶接線７１における溶接端部７２以外の部分に３６０度囲まれるように配置されている。ここでいう「３６０度囲まれる」とは、溶接端部７２と外周線７３上の任意の点とを結ぶ直線が必ず溶接線７１と交わることを意味する。 The weld line 71 is formed by laser welding similarly to the weld line 61 of the first embodiment, and has a C-shape including an arc 711, but the shape in the vicinity of the start point and end point of welding is different. That is, each weld end 62 of the weld line 61 is the end of a straight line portion extended from the arc 611, whereas each weld end 72 of the weld line 71 is further inside the arc 711 from the opening 710. This is the end of the arc 712 drawn to wrap around. For this reason, each welding end part 72 is arrange | positioned spaced apart from the outer periphery line 73 which is one virtual line surrounding the welding construction part 7 with the shortest length. In particular, in the present embodiment, each weld end 72 is disposed so as to be surrounded by a portion other than the weld end 72 in the weld line 71 by 360 degrees. Here, “being surrounded by 360 degrees” means that a straight line connecting the weld end 72 and an arbitrary point on the outer circumferential line 73 always intersects the weld line 71.
以上詳述した第２実施形態によれば、前述した第１実施形態の（１ａ）の効果に加え、以下の効果が得られる。
（２ａ）溶接線７１の溶接端部７２は、溶接線７１に３６０度囲まれている。このような構成によれば、溶接施工部７にどの方向から荷重が加わった場合にも、各溶接端部７２よりも先に、例えば円弧７１１など、溶接線７１における溶接端部７２以外の部分に応力がかかるため、各溶接端部７２に応力が集中することを抑制することができる。
According to the second embodiment described in detail above, in addition to the effect (1a) of the first embodiment described above, the following effect can be obtained.
(2a) The weld end 72 of the weld line 71 is surrounded by the weld line 71 at 360 degrees. According to such a configuration, even if a load is applied to the welding work portion 7 from any direction, a portion other than the welding end portion 72 in the welding line 71 such as an arc 711 prior to each welding end portion 72. Therefore, the stress can be prevented from concentrating on each weld end 72.
なお、上記第１及び第２実施形態では、インパネリインフォースメント１０が溶接構造物の一例に相当し、大径パイプ２が第１の部材の一例に相当し、ブレースブラケット４が第２の部材の一例に相当する。 In the first and second embodiments, the instrument panel reinforcement 10 corresponds to an example of a welded structure, the large-diameter pipe 2 corresponds to an example of a first member, and the brace bracket 4 corresponds to an example of a second member. It corresponds to an example.
［３．他の実施形態］
以上、本発明の実施形態について説明したが、本発明は、上記実施形態に限定されることなく、種々の形態を取り得ることは言うまでもない。
[3. Other Embodiments]
As mentioned above, although embodiment of this invention was described, it cannot be overemphasized that this invention can take a various form, without being limited to the said embodiment.
（３ａ）上記各実施形態では、Ｃ字状の溶接線６１，７１を例示したが、溶接線の形状はこれに限定されるものではない。例えば、溶接線６１，７１とは形状の異なるＣ字状であってもよく、Ｃ字状以外の形状であってもよい。なお、ここでいう「Ｃ字状」とは、全体としてある部分を取り囲む形状であって、閉じた形状（Ｏ字状）ではなく、開口部が形成された形状を意味する。すなわち、厳密なＣの形状が要求されるものではなく、例えば第１実施形態のように、円弧６１１の間や開口部６１０の近辺など、少なくとも一部に直線部分が含まれてもよい。また例えば、円弧６１１は、開口部６１０の中心を軸として対称に配置されていなくてもよく、各円弧６１１の大きさが異なっていてもよい。 (3a) In each of the above embodiments, the C-shaped welding lines 61 and 71 are exemplified, but the shape of the welding line is not limited thereto. For example, the welding lines 61 and 71 may have a C-shape different from the shape, or may have a shape other than the C-shape. Note that the “C-shape” referred to here is a shape surrounding a portion as a whole, and means a shape in which an opening is formed, not a closed shape (O-shape). That is, a strict C shape is not required, and for example, as in the first embodiment, a linear portion may be included in at least a part such as between the arcs 611 or in the vicinity of the opening 610. Further, for example, the arcs 611 may not be arranged symmetrically with the center of the opening 610 as an axis, and the sizes of the arcs 611 may be different.
（３ｂ）上記第１実施形態では、溶接施工部６が４本の溶接線６１を有する構成を例示し、上記第２実施形態では、溶接施工部７が１本の溶接線７１を有する構成を例示したが、溶接線の本数はこれに限定されるものではなく、何本であってもよい。 (3b) In the said 1st Embodiment, the welding construction part 6 illustrated the structure which has the four welding lines 61, and the said 2nd embodiment has the structure in which the welding construction part 7 has the one welding line 71. Although illustrated, the number of welding lines is not limited to this, and any number may be used.
（３ｃ）上記第２実施形態では、溶接線７１の溶接端部７２が溶接線７１に３６０度囲まれている形状としてＣ字状の形状を例示したが、これに限定されるものではなく、例えばＳ字状の形状でもよい。また例えば、溶接施工部が複数本の溶接線を有し、各溶接端部がいずれかの溶接線に３６０度囲まれるようにしてもよい。例えば、図６に示す変形例の溶接施工部９は、２本の溶接線９１１の各溶接端部が、溶接線９１１の内部側に若干回り込むように配置される。その結果、各溶接線９１１の各溶接端部が、いずれかの溶接線９１１に３６０度囲まれる。このような変形例によっても、第２実施形態と同様の効果が得られる。 (3c) In the second embodiment, the C-shaped shape is exemplified as the shape in which the weld end 72 of the weld line 71 is surrounded by the weld line 71 by 360 degrees, but the present invention is not limited to this. For example, an S-shape may be used. Further, for example, the welding construction part may have a plurality of welding lines, and each welding end part may be surrounded by one of the welding lines at 360 degrees. For example, the welding execution part 9 of the modified example shown in FIG. 6 is arranged so that each welding end of the two welding lines 911 slightly wraps around the inside of the welding line 911. As a result, each weld end of each weld line 911 is surrounded by one of the weld lines 911 at 360 degrees. Also by such a modification, the effect similar to 2nd Embodiment is acquired.
（３ｄ）上記各実施形態では、大径パイプ２とブレースブラケット４との溶接部に本発明が適用された構成を例示したが、これに限定されるものではない。例えば、本発明は、インパネリインフォースメント１０における他の溶接部に適用されてもよい。また例えば、本発明は、車両を構成する他の溶接構造物に適用されてもよい。また例えば、本発明は、車両以外で用いられる溶接構造物に適用されてもよい。 (3d) In the above embodiments, the configuration in which the present invention is applied to the welded portion between the large-diameter pipe 2 and the brace bracket 4 is exemplified, but the present invention is not limited to this. For example, the present invention may be applied to other welds in the instrument panel reinforcement 10. Also, for example, the present invention may be applied to other welded structures that constitute a vehicle. Further, for example, the present invention may be applied to a welded structure used other than a vehicle.
（３ｅ）上記実施形態における１つの構成要素が有する機能を複数の構成要素として分散させたり、複数の構成要素が有する機能を１つの構成要素に統合したりしてもよい。また、上記実施形態の構成の少なくとも一部を、同様の機能を有する公知の構成に置き換えてもよい。また、上記実施形態の構成の一部を、課題を解決できる限りにおいて省略してもよい。また、上記実施形態の構成の少なくとも一部を、他の上記実施形態の構成に対して付加、置換等してもよい。なお、特許請求の範囲に記載の文言から特定される技術思想に含まれるあらゆる態様が本発明の実施形態である。 (3e) The functions of one component in the above embodiment may be distributed as a plurality of components, or the functions of a plurality of components may be integrated into one component. Further, at least a part of the configuration of the above embodiment may be replaced with a known configuration having the same function. Moreover, you may abbreviate | omit a part of structure of the said embodiment as long as a subject can be solved.
