しかしながら、特許文献１に開示された製造方法は、熱圧着プレス機内に、金属部材と樹脂部材とをセットし、熱圧着プレス機を一方向に稼働させて熱圧着させる方法であるため、金属部材と樹脂部材との接合面を１つとする接合構造体の製造はできるものの、例えば、金属部材の周囲に樹脂部材を接合させる接合面を複数とする接合構造体を製造することはできなかった。   However, the manufacturing method disclosed in Patent Document 1 is a method in which a metal member and a resin member are set in a thermocompression press machine, and the thermocompression press machine is operated in one direction so as to perform thermocompression.

−接合構造体の構成−
まず、本発明の第１実施形態の接合構造体について説明する。本実施形態の接合構造体１は、金属部材２ａの外側面と樹脂部材３ａとが接合された複数の接合領域ＢＦ１を有する。 −Composition structure−
First, the bonded structure according to the first embodiment of the present invention will be described. The joint structure 1 of the present embodiment has a plurality of joint regions BF1 in which the outer surface of the metal member 2a and the resin member 3a are joined.

金属部材２ａの一例としては、鉄系金属、ステンレス系金属、銅系金属、アルミ系金属、マグネシウム系金属、および、それらの合金が挙げられる。また、金属成型体であってもよく、亜鉛ダイカスト、アルミダイカスト、粉末冶金などであってもよい。   As an example of the metal member 2a, iron metal, stainless steel, copper metal, aluminum metal, magnesium metal, and alloys thereof can be cited. Moreover, a metal molding may be sufficient and zinc die-casting, aluminum die-casting, powder metallurgy, etc. may be sufficient.

本実施形態の金属部材２ａは、直方体形状であるが、金属部材２ａの形状は、この例に限られず、円柱形状であってもよい。金属部材２ａは、本体部２１ａと、後述する接合構造体の製造方法における押圧工程時に樹脂部材３ａを支持する支持部２２ａを備えている。本実施形態では直方体形状の本体部２１ａにおける支持部２２ａ側の外側面の四面を接合領域ＢＦ１としている。   Although the metal member 2a of this embodiment is a rectangular parallelepiped shape, the shape of the metal member 2a is not limited to this example, and may be a cylindrical shape. The metal member 2a includes a main body portion 21a and a support portion 22a that supports the resin member 3a during a pressing step in the manufacturing method of the bonded structure described later. In the present embodiment, the four outer surfaces of the rectangular parallelepiped main body portion 21a on the support portion 22a side are used as the bonding region BF1.

金属部材２ａの接合領域ＢＦ１には、金属部材２ａの表面に開口を有する凹状部ｏが形成されている。凹状部ｏは、平面的に見てほぼ円形の非貫通孔であり、金属部材２ａの表面に複数形成されている。なお、凹状部ｏの形状は、断面が凹形状であれば、例えば、溝状であってもよい。   In the joining region BF1 of the metal member 2a, a concave portion o having an opening on the surface of the metal member 2a is formed. The concave portion o is a substantially circular non-through hole when viewed in plan, and a plurality of the concave portions o are formed on the surface of the metal member 2a. The shape of the concave portion o may be, for example, a groove shape as long as the cross section is concave.

凹状部ｏの開口径は、３０μｍ以上、１００μｍ以下が好ましい。これは、開口径が３０μｍを下回ると、後述する接合工程において凹状部ｏ内に樹脂部材３ａを十分に閉じ込められず、凹状部ｏへの充填性が悪くなるためである。一方、開口径が１００μｍを上回ると、単位面積あたりの凹状部ｏの数が減少して所望の接合効果が得られない場合があるためである。また、凹状部ｏの深さは、１０μｍ以上であることが好ましい。これは、深さが１０μｍを下回ると、凹状部ｏへの充填性が悪くなるためである。   The opening diameter of the concave portion o is preferably 30 μm or more and 100 μm or less. This is because if the opening diameter is less than 30 μm, the resin member 3a cannot be sufficiently confined in the concave portion o in the bonding step described later, and the filling property into the concave portion o is deteriorated. On the other hand, if the opening diameter exceeds 100 μm, the number of concave portions o per unit area may decrease and a desired bonding effect may not be obtained. Moreover, it is preferable that the depth of the recessed part o is 10 micrometers or more. This is because when the depth is less than 10 μm, the filling property to the concave portion o is deteriorated.

また、凹状部ｏの間隔（所定の凹状部ｏの中心と、所定の凹状部ｏと隣接する凹状部ｏの中心との距離）は、２００μｍ以下であることが好ましい。これは、凹状部ｏの間隔が２００μｍを上回ると、単位面積あたりの凹状部ｏの数が減少して、所望の接合効果が得られない場合があるためである。なお、凹状部ｏの間隔の下限の一例としては、凹状部ｏが重畳して潰れない距離である。また、凹状部ｏの間隔は等間隔であることが好ましい。これは、凹状部ｏが等間隔であると、接合工程時に樹脂部材３ａの熱分布が等方的になるためである。   The interval between the concave portions o (the distance between the center of the predetermined concave portion o and the center of the concave portion o adjacent to the predetermined concave portion o) is preferably 200 μm or less. This is because if the interval between the concave portions o exceeds 200 μm, the number of the concave portions o per unit area decreases, and a desired bonding effect may not be obtained. An example of the lower limit of the interval between the concave portions o is a distance at which the concave portions o are not overlapped and crushed. Moreover, it is preferable that the interval of the recessed part o is an equal interval. This is because the heat distribution of the resin member 3a is isotropic during the joining process when the concave portions o are equally spaced.

凹状部ｏには、後述する樹脂部材３ａが充填されることにより、金属部材２ａと樹脂部材３ａとが接合される。ここで、本実施形態の凹状部ｏには、内側に突出する突出部ｔが形成されている（例えば、図４Ａ参照）。このように凹状部ｏの内周面に、内側に突出する突出部ｔが形成されている場合は、凹状部ｏに樹脂部材３ａが充填されると、突出部ｔによるアンカー効果によって金属部材２ａと樹脂部材３ａとの接合強度を高めることができる。なお、凹状部ｏに突出部ｔが形成されていなくてもよい（例えば、図４Ｂ参照）。   The concave portion o is filled with a resin member 3a described later, whereby the metal member 2a and the resin member 3a are joined. Here, the concave portion o of the present embodiment is formed with a protruding portion t protruding inward (see, for example, FIG. 4A).

−接合構造体の製造方法−
次に、本実施形態に係る接合構造体１の製造方法について説明する。本実施形態に係る接合構造体１の製造方法は、凹状部形成工程と、押圧工程と、接合工程と、を備えている。以下、各工程について説明する。 -Manufacturing method of bonded structure-
Next, a method for manufacturing the bonded structure 1 according to the present embodiment will be described. The manufacturing method of the joined structure 1 according to the present embodiment includes a concave portion forming step, a pressing step, and a joining step. Hereinafter, each step will be described.

・凹状部形成工程
凹状部形成工程は、金属部材２ａにおける接合領域ＢＦ１に、開口を有する凹状部ｏを形成する工程である。 -Recessed part formation process A recessed part formation process is a process of forming the recessed part o which has opening in joining area | region BF1 in the metal member 2a.

凹状部ｏは、レーザ加工処理、ブラスト処理、サンドペーパ処理、陽極酸化処理、放電加工処理、エッチング処理、およびプレス加工処理等の方法で形成される。本実施形態では、レーザ加工処理によって凹状部ｏを形成する方法について詳述する。   The concave portion o is formed by a method such as laser processing, blast processing, sand paper processing, anodizing processing, electric discharge processing, etching processing, or press processing. In the present embodiment, a method for forming the concave portion o by laser processing will be described in detail.

凹状部ｏを形成する加工用レーザの種類としては、パルス発振が可能なものが好ましく、ファイバレーザ、ＹＡＧレーザ、ＹＶＯ4レーザ、半導体レーザ、炭酸ガスレーザ、エキシマレーザが選択でき、レーザの波長を考慮すると、ファイバレーザ、ＹＡＧレーザ、ＹＡＧレーザの第２高調波、ＹＶＯ4レーザ、半導体レーザが好ましい。凹状部ｏは、平面的に見てほぼ円形の非貫通孔であり、金属部材２ａの表面に複数形成される。 As the type of processing laser for forming the concave portion o, a laser capable of pulse oscillation is preferable, and a fiber laser, a YAG laser, a YVO 4 laser, a semiconductor laser, a carbon dioxide gas laser, and an excimer laser can be selected, and the wavelength of the laser is considered. Then, a fiber laser, a YAG laser, a second harmonic of a YAG laser, a YVO 4 laser, and a semiconductor laser are preferable. The concave portion o is a substantially circular non-through hole when seen in a plan view, and a plurality of the concave portions o are formed on the surface of the metal member 2a.

凹状部ｏを形成する装置の一例としては、オムロン製のファイバレーザマーカＭＸＺ２０００またはＭＸ−Ｚ２０５０を挙げることができる。このファイバレーザマーカでは、１パルスが複数のサブパルスで構成されるレーザを照射することが可能である。このため、レーザのエネルギーを深さ方向に集中させやすいので、凹状部ｏを形成するのに好適である。   As an example of an apparatus for forming the concave portion o, an Omron fiber laser marker MXZ2000 or MX-Z2050 can be cited. With this fiber laser marker, it is possible to irradiate a laser where one pulse is composed of a plurality of subpulses. For this reason, the energy of the laser is easily concentrated in the depth direction, which is suitable for forming the concave portion o.

具体的には、金属部材２ａにレーザが照射されると、金属部材２ａが局部的に溶融されることにより凹状部ｏの形成が進行する。このとき、レーザが複数のサブパルスで構成されているため、溶融された金属部材２ａが飛散されにくく、凹状部ｏの近傍に堆積されやすい。そして、凹状部ｏの形成が進行すると、溶融された金属部材２ａが凹状部ｏの内部に堆積されることにより、凹状部ｏの内周面に、内側に突出する突出部ｔが形成される（図４Ａ参照）。なお、レーザが複数の単パルスで構成されている場合は、突出部ｔが形成されない（図４Ｂ参照）。   Specifically, when the metal member 2a is irradiated with a laser, the metal member 2a is locally melted to advance the formation of the concave portion o. At this time, since the laser is composed of a plurality of sub-pulses, the molten metal member 2a is difficult to be scattered and easily deposited in the vicinity of the concave portion o. Then, as the formation of the concave portion o proceeds, the molten metal member 2a is deposited inside the concave portion o, thereby forming a protruding portion t protruding inward on the inner peripheral surface of the concave portion o. (See FIG. 4A). In addition, when the laser is composed of a plurality of single pulses, the protrusion t is not formed (see FIG. 4B).

なお、上記ファイバレーザマーカによる加工条件としては、サブパルスの１周期が１５ｎｓ以下であることが好ましい。これは、サブパルスの１周期が１５ｎｓを超えると、熱伝導によりエネルギーが拡散しやすくなり、突出部ｔを有する凹状部ｏを形成しにくくなるためである。なお、サブパルスの１周期は、サブパルスの１回分の照射時間と、そのサブパルスの照射が終了されてから次回のサブパルスの照射が開始されるまでの間隔との合計時間である。   As a processing condition by the fiber laser marker, it is preferable that one period of the sub-pulse is 15 ns or less. This is because when one period of the sub-pulse exceeds 15 ns, energy is easily diffused by heat conduction, and it becomes difficult to form the concave portion o having the protruding portion t. Note that one cycle of the subpulse is a total time of the irradiation time for one subpulse and the interval from the end of the irradiation of the subpulse to the start of the irradiation of the next subpulse.

また、上記ファイバレーザマーカによる加工条件としては、１パルスのサブパルス数は、２以上５０以下であることが好ましい。これは、サブパルス数が５０を超えると、サブパルスの単位あたりの出力が小さくなり、突出部ｔを有する凹状部ｏを形成しにくくなるためである。   Further, as a processing condition by the fiber laser marker, the number of subpulses of one pulse is preferably 2 or more and 50 or less. This is because if the number of subpulses exceeds 50, the output per unit of subpulses becomes small, and it becomes difficult to form the concave portion o having the protruding portion t.

・押圧工程
押圧工程は、スリーブ５１を用いて金属部材２ａに樹脂部材３ａを接合領域ＢＦ１で接触させる工程である（図２参照）。 -Pressing step The pressing step is a step of bringing the resin member 3a into contact with the metal member 2a using the sleeve 51 in the bonding region BF1 (see FIG. 2).

スリーブ５１は、金属部材２１ａの本体部２１ａが入り込む開口５１ｂが形成されており、開口端５１ａによって樹脂部材３ａの膨出部３１ａを金属部材２ａに押圧させるものである。   The sleeve 51 is formed with an opening 51b into which the main body portion 21a of the metal member 21a enters, and the bulging portion 31a of the resin member 3a is pressed against the metal member 2a by the opening end 51a.

スリーブ５１には、スリーブ５１を昇降させる昇降手段と、樹脂部材３ａを加熱溶融させるための加熱手段と、が備えられている。昇降手段としては、プレス方式、圧縮エア方式、加重方式、及び、メカニカル方式等が挙げられる。また、スリーブ５１の開口端５１ａは、樹脂部材３ａの膨出部３１ａの傾斜面３２ａに対応して傾斜されている。   The sleeve 51 includes elevating means for elevating the sleeve 51 and heating means for heating and melting the resin member 3a. Examples of the lifting means include a press method, a compressed air method, a weighting method, and a mechanical method. Moreover, the opening end 51a of the sleeve 51 is inclined corresponding to the inclined surface 32a of the bulging portion 31a of the resin member 3a.

本実施形態の押圧工程では、上述したスリーブ５１を用いて金属部材２ａに樹脂部材３ａを接合領域ＢＦ１で接触させる。   In the pressing step of the present embodiment, the resin member 3a is brought into contact with the metal member 2a in the joining region BF1 using the sleeve 51 described above.

具体的に詳述すると、まず、樹脂部材３ａの貫通孔ｈに金属部材２ａの本体部２１ａを挿通させて（図１参照）、金属部材２ａの支持部２２ａと樹脂部材３ａの係合部３３ａとを係合させる（図２参照）。そして、樹脂部材３ａの上方に配置されたスリーブ５１の加熱手段によってスリーブ５１を加熱させ、昇降手段によってスリーブ５１を樹脂部材３ａに向けて下降させる。スリーブ５１の開口端５１ａが樹脂部材３ａの膨出部３１ａを押圧すると、膨出部３１ａの傾斜面３２ａにより金属部材２ａに向かう方向の押圧力が大きくなり、樹脂部材３ａは、金属部材２ａに向けて押圧される。従って、押圧が掛かる方向を効果的に変えるために、傾斜角θ１は、１００°〜１７０°とすることが好ましい。   Specifically, first, the main body portion 21a of the metal member 2a is inserted into the through hole h of the resin member 3a (see FIG. 1), and the support portion 22a of the metal member 2a and the engaging portion 33a of the resin member 3a. Are engaged (see FIG. 2). Then, the sleeve 51 is heated by the heating means of the sleeve 51 disposed above the resin member 3a, and the sleeve 51 is lowered toward the resin member 3a by the elevating means. When the open end 51a of the sleeve 51 presses the bulging portion 31a of the resin member 3a, the pressing force in the direction toward the metal member 2a is increased by the inclined surface 32a of the bulging portion 31a, and the resin member 3a is applied to the metal member 2a. It is pressed toward. Therefore, in order to effectively change the direction in which the pressure is applied, the inclination angle θ1 is preferably set to 100 ° to 170 °.

ここで、樹脂部材３ａには係合部３３ａが設けられているので、当該押圧工程によりスリーブ５１で樹脂部材３ａを押圧しても、係合部３３ａと支持部２２ａとを係合させて効果的に押圧させることができる。なお、樹脂部材３ａの位置を固定することができる場合は、樹脂部材３ａに係合部３３ａを設けなくてもよい。   Here, since the engaging part 33a is provided in the resin member 3a, even if the resin member 3a is pressed by the sleeve 51 by the pressing step, the engaging part 33a and the support part 22a are engaged to effect. Can be pressed. In addition, when the position of the resin member 3a can be fixed, the engaging part 33a does not need to be provided in the resin member 3a.

・接合工程
接合工程は、膨出部３１ａを含む接合領域ＢＦ１付近の樹脂部材３ａを溶融するとともに、金属部材２ａの凹状部ｏに樹脂部材３ａを充填して接合する工程である。 Bonding process The bonding process is a process of melting the resin member 3a in the vicinity of the bonding region BF1 including the bulging portion 31a and filling the concave member o of the metal member 2a with the resin member 3a for bonding.

本実施形態では、スリーブ５１が加熱手段によって加熱されているので、スリーブ５１を樹脂部材３ａに接触させることにより、膨出部３１ａを含む樹脂部材３ａが溶融する。この溶融された樹脂部材３ａが、金属部材２ａの凹状部ｏに充填される。その後、樹脂部材３ａが固化されることにより、樹脂部材３ａが金属部材２ａに接合された接合構造体１を製造できる（図３参照）。   In this embodiment, since the sleeve 51 is heated by the heating means, the resin member 3a including the bulging portion 31a is melted by bringing the sleeve 51 into contact with the resin member 3a. The melted resin member 3a is filled in the concave portion o of the metal member 2a. Thereafter, the resin member 3a is solidified, whereby the bonded structure 1 in which the resin member 3a is bonded to the metal member 2a can be manufactured (see FIG. 3).

本実施形態では、凹状部ｏの内周面に、内側に突出する突出部ｔが形成されているので、凹状部ｏに樹脂部材３ａが充填されると、突出部ｔによるアンカー効果によって金属部材２ａと樹脂部材３ａとの接合強度を高めることができる（図４Ａ参照）。   In this embodiment, since the protrusion part t which protrudes inside is formed in the internal peripheral surface of the concave part o, if the resin member 3a is filled into the concave part o, a metal member will be carried out by the anchor effect by the protrusion part t. The bonding strength between 2a and the resin member 3a can be increased (see FIG. 4A).

以上、説明したとおり、本実施形態に係る接合構造体１の製造方法によれば、金属部材２ａと樹脂部材３ａとを複数の接合面で接合する場合でも、押圧工程によって、樹脂部材３ａの膨出部を押圧させて、接合工程によって、樹脂部材３ａと金属部材２ａとを接合させることができるので、金属部材２ａと樹脂部材３ａとの接合に接合ばらつきを抑制することができる。   As described above, according to the manufacturing method of the bonded structure 1 according to the present embodiment, even when the metal member 2a and the resin member 3a are bonded at a plurality of bonding surfaces, the swelling of the resin member 3a is performed by the pressing process. Since the resin member 3a and the metal member 2a can be bonded by the bonding step by pressing the protruding portion, it is possible to suppress bonding variation in the bonding between the metal member 2a and the resin member 3a.

−接合構造体の構成−
まず、本発明の第４実施形態の接合構造体１について説明する。本実施形態の接合構造体１は、金属部材２ｄの外側面と樹脂部材３ｄとが接合された複数の接合領域ＢＦ４を有する（図７参照）。 −Composition structure−
First, the joining structure 1 of 4th Embodiment of this invention is demonstrated. The joint structure 1 of the present embodiment has a plurality of joint regions BF4 in which the outer surface of the metal member 2d and the resin member 3d are joined (see FIG. 7).

本実施形態の金属部材２ｄは、直方体形状であり、本体部２１ｄと、後述する押圧工程時に樹脂部材３ａを支持する支持部２２ａと、本体部２１ｄと支持部２２ｄとを結ぶ接続部２３とが備えられている。なお、金属部材２ｄの形状は、例えば、円柱形状であってもよい。   The metal member 2d of the present embodiment has a rectangular parallelepiped shape, and includes a main body portion 21d, a support portion 22a that supports the resin member 3a during a pressing process described later, and a connection portion 23 that connects the main body portion 21d and the support portion 22d.

次に、本実施形態に係る接合構造体１の製造方法について説明する。本実施形態に係る接合構造体１の製造方法は、凹状部形成工程と、押圧工程と、接合工程と、を備えている。以下、各工程について説明する。 -Manufacturing method of bonded structure-
Next, a method for manufacturing the bonded structure 1 according to the present embodiment will be described. The manufacturing method of the joined structure 1 according to the present embodiment includes a concave portion forming step, a pressing step, and a joining step. Hereinafter, each step will be described.

・凹状部形成工程
凹状部形成工程は、第１実施形態で説明したとおりであるので、説明を省略する。 -Concave part formation process Since the concave part formation process is as having demonstrated in 1st Embodiment, description is abbreviate | omitted.

・押圧工程
押圧工程は、押当装置５６を用いて金属部材２ｄに樹脂部材３ｄを接合領域ＢＦ４で接触させる工程である（図８参照）。 -Pressing process The pressing process is a process of bringing the resin member 3d into contact with the metal member 2d in the bonding region BF4 using the pressing device 56 (see FIG. 8).

押当装置５６には、樹脂部材３ｄの上方から樹脂部材３ｄを垂直方向に押圧する押圧手段が備えられている。押圧手段としては、プレス方式、圧縮エア方式、加重方式、及び、メカニカル方式等が挙げられる。   The pressing device 56 is provided with pressing means for pressing the resin member 3d in the vertical direction from above the resin member 3d. Examples of the pressing means include a press method, a compressed air method, a weighting method, and a mechanical method.

本実施形態の押圧工程では、上述した押当装置５６を用いて金属部材２ｄに樹脂部材３ｄを接合領域ＢＦ４で接触させる。   In the pressing step of the present embodiment, the resin member 3d is brought into contact with the metal member 2d at the bonding region BF4 using the pressing device 56 described above.

具体的に詳述すると、まず、樹脂部材３ｄの貫通孔ｈに金属部材２ｄの本体部２１ｄを挿通させ（図７参照）、金属部材２ｄの支持部２２ｄと樹脂部材３ｄの係合部３３ｄとを係合させる（図８参照）。そして、押当装置５６を樹脂部材３ｄに向けて垂直方向に下降させて、樹脂部材３ｄを金属部材２ｄに向けて押圧する。   Specifically, first, the main body portion 21d of the metal member 2d is inserted into the through hole h of the resin member 3d (see FIG. 7), and the support portion 22d of the metal member 2d and the engaging portion 33d of the resin member 3d Are engaged (see FIG. 8). Then, the pressing device 56 is lowered in the vertical direction toward the resin member 3d, and the resin member 3d is pressed toward the metal member 2d.

・接合工程
接合工程は、レーザ加熱装置５５を用いて金属部材２ｄと樹脂部材３ｄとを接合する工程である。 Bonding process The bonding process is a process of bonding the metal member 2d and the resin member 3d using the laser heating device 55.

レーザ加熱装置５５は、樹脂部材３ｄを溶融させることができる装置であり、例えばファイバレーザ、ＹＡＧレーザ、ＹＶＯ4レーザ、半導体レーザ、炭酸ガスレーザ、エキシマレーザである。 The laser heating device 55 is a device that can melt the resin member 3d, and is, for example, a fiber laser, a YAG laser, a YVO 4 laser, a semiconductor laser, a carbon dioxide gas laser, or an excimer laser.

本実施形態の接合工程では、上述したレーザ加熱装置５５を用いて金属部材２ｄと樹脂部材３ｄとを接合させる（図８参照）。   In the joining process of this embodiment, the metal member 2d and the resin member 3d are joined using the laser heating device 55 described above (see FIG. 8).

具体的に詳述すると、レーザ加熱装置５５からのレーザを樹脂部材３ｄの膨出部３１ｄに向けて照射することにより、膨出部３１ｄを含む樹脂部材３ｄが溶融する。この溶融された樹脂部材３ｄが、金属部材２ｄの凹状部ｏに充填される。その後、樹脂部材３ｄが固化されることにより、樹脂部材３ｄが金属部材２ｄに接合された接合構造体１を製造できる（図９参照）。   More specifically, the resin member 3d including the bulging portion 31d is melted by irradiating the laser from the laser heating device 55 toward the bulging portion 31d of the resin member 3d. The molten resin member 3d is filled in the concave portion o of the metal member 2d. Thereafter, the resin member 3d is solidified, whereby the bonded structure 1 in which the resin member 3d is bonded to the metal member 2d can be manufactured (see FIG. 9).

本実施形態では、レーザ加熱装置５５からのレーザを膨出部３１ｄに向けて精度よく局所的に照射することができるので、不必要に樹脂部材３ｄを溶融させることを抑制することができる。また、膨出部３１ｄは、樹脂部材３ｄにおいて厚みが比較的に厚いので、溶融体積を稼ぐことができる。   In this embodiment, since the laser from the laser heating device 55 can be locally irradiated with high precision toward the bulging portion 31d, it is possible to suppress unnecessary melting of the resin member 3d. Further, since the bulging portion 31d has a relatively large thickness in the resin member 3d, it can earn a molten volume.

なお、上記に示した本発明の実施形態はいずれも本発明を具体化した例であって、本発明の技術的範囲を限定する性格のものではない。   The embodiments of the present invention described above are all examples embodying the present invention, and are not of a nature that limits the technical scope of the present invention.
