Description

【０００１】
【発明の属する技術分野】
本発明は、こんろ等の調理器に使用する五徳、その製造方法及び調理器に関する。
【０００２】
【従来の技術】
従来、流し台に一体にこんろを取り付けた調理器が使用されている。このような調理器には、複数の火口に対して鍋等の調理用容器を支持する五徳が設けられている。この種の五徳は、複数の火口を包囲する本体フレームを有し、その本体フレームに梁を取り付けるとともに、火口を中心に放射状に複数の爪を取り付け、爪によって鍋等の調理用容器を支持するものである。
【０００３】
【発明が解決しようとする課題】
ところで、従来の五徳では、本体フレームに梁や爪をプロジェクション溶接によって固着する方法が取られている。製造上、溶接設備の他、五徳の形態に合わせて溶接部の位置決めするための治具が必要であり、製造工程上、梁と爪とを溶接して一体とし、それと本体フレームとを溶接した後、本体フレーム側には更に単品の爪を溶接する等、溶接作業には治具の設計に加え溶接工程が複雑化しており、溶接不良が製品の歩留りを低下させるという問題があった。溶接不良の発生を防止するには、溶接電極の保守管理が必要である上、十分な注意を払っていても、溶接箇所が多数に亘る場合には溶接不良の発生を防止できないという問題があった。これが製品価格を高くする原因にもなっていた。
【０００４】
そこで、本発明は、溶接による固着手段から機械加工による結合を以て組立作業の簡略化を実現した五徳、その製造方法及び調理器を提供することを目的とする。
【０００５】
【課題を解決するための手段】
本発明は、図１〜図２２に例示するように、本体フレーム（２０）と取付部材（梁部３４、爪部３６、３８、４０、５０）とを加締めによる機械的な結合とした五徳を実現し、その製造方法、五徳を用いた調理器を実現したものである。溶接から機械的な加締め結合としたことにより、従来の溶接不良等の組立不良の発生を防止できる。
【０００６】
本発明の五徳は、金属材料で形成された本体フレームと取付部材とを有し、前記本体フレーム側に前記取付部材の厚みより小さい幅の第１の凹部を形成するとともに、前記取付部材側に前記本体フレームの厚みより小さい幅の部分を有する第２の凹部を形成し、これら第１及び第２の凹部を噛み合わせ、前記本体フレームと前記取付部材とを加締めて結合させ、結合させた前記本体フレームと前記取付部材における前記第１及び第２の凹部の対向面部間に間隙を設けてなる構成である。本体フレーム及び取付部材は金属材料で形成され、例えば、金属板から打ち抜き加工で形成される。ここで、取付部材とは、本体フレームを支持部材とし、それに取り付けられる梁や爪等の部品であり、これら本体フレーム及び取付部材を以て五徳が構成される。本体フレームと取付部材との結合部分には、第１及び第２の凹部が形成されており、本体フレーム側の第１の凹部の幅は取付部材の厚みより小さく、また、取付部材側の第２の凹部の幅は本体フレームの厚みより小さく設定する。これら第１及び第２の凹部を対向し、両者を噛み合わせて嵌合させて結合されている。このような構成とすれば、金属材料が持つ弾性と厚みとを以て、両者の加締め結合は溶接と同等以上の固着強度及び形状保持力が実現できる。
【０００７】
また、本発明の五徳においては、結合させた前記本体フレームと前記取付部材における前記第１及び第２の凹部の対向面部間に間隙（４８）を設けることで、本体フレームと取付部材との加締め固定に当たって、各凹部の最奥部分に不要な応力が作用することがなく、素材の持つ弾性を十分に機能させ、強固に機械的な結合ができる。その上、五徳の取付部材側に調理容器が載せられて相当な荷重が加わっても、その荷重による取付部材と本体フレームとの間に加わる応力による歪みが前記間隙で吸収される結果、固定強度の低下やがたつきの防止が図られる。
【０００８】
また、本発明の五徳は、金属材料で形成された本体フレームと取付部材とを有し、前記本体フレーム側に前記取付部材の厚みより小さい幅の第１の凹部を形成するとともに、前記取付部材側に前記本体フレームの厚みより小さい幅の部分を有する第２の凹部を形成し、これら第１及び第２の凹部を噛み合わせ、前記本体フレームと前記取付部材とを加締めて結合させ、前記第１又は第２の凹部の何れか一方を平行壁面で形成し、他方の被着面部を凹凸面としてなる構成である。即ち、各凹部の幅は互いに噛み合わせる本体フレーム及び取付部材の厚みより小さいことと、フラット面からの凹部と凹凸面からなる内壁面を持つ凹部とを噛み合わせたことにより、幅及び内壁面の形態の組み合わせで両者の加締め強度が高く、強固な機械的な固着状態が実現される。
【０００９】
そして、本発明の五徳の製造方法は、金属板を打ち抜き加工することにより本体フレームと取付部材とを形成する工程と、前記打ち抜き加工と同時又は別工程で前記本体フレーム又は前記取付部材の結合部に第１又は第２の凹部を形成する工程と、組み立てた前記本体フレームの前記第１の凹部に前記取付部材の前記第２の凹部を位置決めした後、両者に一定間隔の結合力を作用させ、前記第１及び第２の凹部を嵌合させ、前記本体フレームに前記取付部材を結合させる工程と、結合させた前記本体フレームと前記取付部材における前記第１及び第２の凹部の対向面部間に間隙を形成する工程とを含む構成である。このような工程により、従来のような溶接による手間がなく、組立作業の簡略化とともに頑丈な五徳を製造できる。
また、本発明の五徳の製造方法は、金属板を打ち抜き加工することにより本体フレームと取付部材とを形成する工程と、前記打ち抜き加工と同時又は別工程で前記本体フレーム又は前記取付部材の結合部に第１又は第２の凹部を形成する工程と、組み立てた前記本体フレームの前記第１の凹部に前記取付部材の前記第２の凹部を位置決めした後、両者に一定間隔の結合力を作用させ、前記第１及び第２の凹部を嵌合させ、前記本体フレームに前記取付部材を結合させる工程と、前記第１又は第２の凹部の何れか一方を平行壁面で形成し、他方の被着面部を凹凸面に形成する工程とを含む構成としてもよい。
【００１０】
また、前記取付部材は、第１及び第２の部材を有し、前記本体フレームに前記第１の部材（梁部３４）を結合させた後、前記第２の部材（爪部３６、３８、４０、５０）を前記本体フレーム及び前記第１の部材に結合させる。このような取付部材を第１及び第２の部材の部品構成とし、第１及び第２の部材を本体フレームに対して２工程により組み立てるので、工程の簡略化とともに、第１工程で本体フレームの強化を図り、その上で第２工程で最終組み立てができ、歪みの発生がなく、形状精度の高い五徳が得られる。
【００１１】
また、本発明の調理器は、前記五徳を用いてなることを特徴とする。このような五徳を用いたことにより、製品コストを抑えることができ、溶接による固着形態には見られない外観的にも優れた製品を提供することができる。
【００１２】
【発明の実施の形態】
以下、本発明を図面に示した実施形態を参照して詳細に説明する。
【００１３】
図１ないし図３は、本発明の五徳の一実施形態である調理器を示し、図１はその平面図、図２はその正面図、図３はその側面図である。
【００１４】
この調理器２は、キッチンセットの装置本体に流し台等とともに組み込まれるものであるが、本発明は、このような形態のものに限定されるものではない。この調理器２には、上面部にバーナを備えた３つの火口４、６、８及び排気口１０が備えられ、その下部にはグリル１２が設置されている。火口４、６、８側の上面には単一の受け皿１４が設けられ、この受け皿１４の火口４、６側には第１の五徳１６、火口８側には第２の五徳１８が着脱可能に載置されている。この実施形態では、３つの火口４、６、８を２分する形態で一対の五徳１６、１８を設置しているが、これらの五徳１６、１８を一体化して一つの五徳として構成してもよい。
【００１５】
次に、図４〜図１２は、第１の五徳１６の具体的な構成例を示し、図４はその平面図、図５はその正面図、図６はその側面図、図７はその斜視図、図８はその部分を示す分解斜視図、図９は本体フレームの平面図、図１０は梁部の正面図、図１１及び図１２は爪部の正面図である。
【００１６】
五徳本体を成す本体フレーム２０は、一定幅の金属帯からなる無端環状体であって、部材の厚み側を上下方向として設置されている。この本体フレーム２０は、大まかにみれば長方形であるが、その各角部は一定の湾曲部２２を形成しており、各辺部は、一定幅の立壁を成すとともに、長辺側には湾曲部２２を延長する形態で直線状を成す一対の短いフラット部２４を形成するとともに屈曲部２６を設けて長いフラット部２８が形成され、また、短辺側には湾曲部２２に一対の屈曲部３０を設けて直線状を成すフラット部３２が形成されている。フラット部２４又はフラット部２８とフラット部３２の延長線は大小の長方形を構成する。
【００１７】
また、この本体フレーム２０のフラット部２８の中央部には一定の間隔を設けて取付部材の第１の部材として平板状を成す２枚の梁部３４が取り付けられ、各梁部３４は火口４、６の間隔内に本体フレーム２０の各フラット部２８と直行する形態で取り付けられている。各梁部３４も本体フレーム２０と同様に立壁を成している。そして、本体フレーム２０及び梁部３４には、取付部材の第２の部材として６枚構成を成す形態の異なる爪部３６、３８、４０が取り付けられており、爪部３６、３８と本体フレーム２０のフラット部２８又はフラット部３２と直交し、又は、爪部４０と梁部３４とは直交する形態で両者が固定されており、各爪部３８、４０は中間部で所定角度だけ屈曲させたことにより、爪部３６とともに火口４、６を中心に一定の角度、例えば、６０度の角度間隔を以て放射状に配設されている。即ち、このような角度間隔を以て爪部３６、３８、４０を放射状に配置したことにより、火口４、６に設置される調理用容器の荷重を６枚の爪部３６、３８、４０に分散させるとともに、爪部３６、３８と本体フレーム２０の固定、爪部４０と梁部３４との固定角度を９０度に設定することにより、固定の単純化を実現している。
【００１８】
また、各梁部３４の端部の突出長は、フラット部２４とフラット部２８との屈曲範囲内に置かれており、この実施形態ではフラット部２４の外壁面に一致させてある。また、各爪部３６、３８の後部側の突出長は、フラット部２４、２８間の屈曲範囲内又は湾曲部２２の外壁面内に置かれており、この実施形態ではフラット部２４の外壁面、又は湾曲部２２の外壁面に一致させてある。このような形態とすることで、外壁面側への突出を軽減し、五徳１６の実質的なフラット形状を実現している。
【００１９】
そして、本体フレーム２０には、図１３及び図１４に示すように、梁部３４及び爪部３６、３８を固定する部分に第１の凹部として溝部４２が形成され、同様に梁部３４にも爪部４０を固定する箇所に溝部４２が形成されている。そして、梁部３４は、図７、図８及び図１０に示すように、コ字形とすることにより、両端部側には図１３及び図１４に示すように、本体フレーム２０に対する固定部４４が形成され、この固定部４４には第２の凹部としての深い溝部４６が形成されている。
【００２０】
本体フレーム２０又は梁部３４側の溝部４２は、本体フレーム２０又は梁部３４を構成する板材の厚みと同等の幅及び深さからなる矩形に形成されているのに対し、固定部４４側の溝部４６は、天井面４６ａをフラット面とするとともに、本体フレーム２０又は梁部３４を構成する板材の厚みより僅かに広い部分と狭い部分とを交互に形成するために、両壁面間を対称とした凸部４６ｂと凹部４６ｃとを交互に形成した緩やかな凹凸面を成している。この実施形態では、本体フレーム２０と梁部３４又は爪部３６、３８との加締め前の仮固定を容易にするとともに、梁部３４と爪部４０との初期的な仮固定を容易にするため、溝部４６の開口部の幅ｄを素材の厚みより僅かに大きく設定し、かつ、角部を湾曲面４６ｄに形成してある。
【００２１】
次に、第１の五徳１６の製造方法について説明する。一定幅の金属帯を切断して成形し、端部を溶接することにより、図９に示す本体フレーム２０を形成する。なお、この本体フレーム２０には、梁部３４及び爪部３６、３８を取り付ける箇所に溝部４２を切削又は打ち抜き等の機械加工により形成する。また、本体フレーム２０と同様の金属板材を打ち抜き加工することにより、２枚の梁部３４、１０枚の爪部３６、３８、４０を形成する。その場合、爪部３６、３８、４０には、溝部４２若しくは溝部４６又はその双方を形成する。
【００２２】
五徳１６の組立にはプレス機を使用し、本体フレーム２０を支持する治具としての金型を用いる。この金型の上に溝部４２側を上方にして本体フレーム２０を設置し、第１段階の加工として、この本体フレーム２０に２枚の梁部３４を位置決めし、仮固定する。その場合、本体フレーム２０の溝部４２に梁部３４の固定部４４の溝部４６を噛み合わせ、両者が互いに直交する形態とする。このように配置した場合、溝部４６が本体フレーム２０の素材の厚みより幅が広いために、本体フレーム２０の上に梁部３４が精度良く位置決めされ、垂直状態となる。この状態でプレス加工、即ち、圧縮加工を施すと、本体フレーム２０側に梁部３４の固定部４４が下降して加締められ、本体フレーム２０と２枚の梁部３４が所定位置に強固に固着状態となる。この結果、本体フレーム２０のフラット部２８間には、一定間隔を成す２枚の梁部３４が橋絡状態で結合されるため、本体フレーム２０の機械的強度は、梁部３４の結合でより強固なものとなる。
【００２３】
次に、本体フレーム２０には、爪部３６、３８を仮固定し、梁部３４には爪部４０を仮固定し、その状態で圧縮加工を施すことにより、本体フレーム２０に梁部３４を固定したのと同様に、溝部４２に溝部４６を噛み合わせ、本体フレーム２０と爪部３６、３８、梁部３４と爪部４０をそれぞれ強固に結合することができる。梁部３４間には、２枚の爪部４０のフラット部４１が橋絡状態で結合されることになり、２枚の梁部３４と２枚の爪部４０のフラット部４１とが格子状となり、本体フレーム２０の中央部で極めて強固な形状保持機能を実現しており、極めて強固な構造体となる。
【００２４】
そして、図１５及び図１６は、本体フレーム２０と梁部３４又は爪部３６、３８、梁部３４と爪部４０との結合状態を示しており、溝部４２の底面４３と溝部４６の天井面４６ａとの間には、僅かの幅ｔの間隙４８を形成する。即ち、本体フレーム２０と梁部３４又は爪部３６、３８との間の結合部間には、高さ方向に間隙４８が設けられているとともに、梁部３４と爪部４０との結合部間にも高さ方向に間隙４８が設けられている。このような間隙４８を設けた構成とすることで、本体フレーム２０又は梁部３４と取付部材である爪部３６、３８、梁部３４と爪部４０との加締め固定に当たって、溝部４２の底面４３と溝部４６の天井面４６ａの近傍の最奥部分に不要な応力、即ち、一定幅に設定されている溝部４２、４６の間隔を必要以上に拡大するような応力を溝部４２、４６の壁面間に作用させることを抑制でき、素材の持つ弾性を十分に機能させ、強固に機械的な結合ができる。また、このような間隙４８は、爪部３６〜４０に作用する荷重や熱に対し、機械的な歪みを吸収する緩衝部として機能し、機械的ながたつきの防止を図ることができ、長時間の使用に耐える製品を実現することができる。
【００２５】
また、本体フレーム２０に対し、爪部３６、３８は、片持ち梁を構成しているが、各爪部３６、３８の固定部４４は、本体フレーム２０の幅方向に噛み合っており、両者の結合状態は極めて強固であって、従来の溶接による固定を越える機械的な強度を実現でき、しかも、複数の爪部３６、３８、４０で均等な荷重分散が図れるので、相当な重量を持つ調理用容器を安定状態に支持できる。
【００２６】
次に、第２の五徳１８について説明する。この五徳１８は、五徳１６と異なって単一の火口８を中央にして調理用容器を支持するものであり、基本的な構成は五徳１６と同様である。即ち、本体フレーム２０は、前後方向の幅が狭いだけで、五徳１６と相似形である。この五徳１８では、２枚の梁部３４を火口８を挟んで設置したものである。そして、２枚の爪部３６と４枚の爪部５０が固着され、先端部側が例えば６０度の角度間隔を以て配設されている。この実施形態では、爪部５０のフラット部５２側に本体フレーム２０と梁部３４に対応して一対の固定部４４が設けられ、この固定部４４側の溝部４６と本体フレーム２０及び梁部３４の溝部４２とが結合され、五徳１６と同様に溝部４２の底面４３と溝部４６の天井面４６ａとの間に間隙４８が形成される。そして、この実施形態では、左右の梁部３４と本体フレーム２０のフラット部３２との間に２枚の爪部５０のフラット部５２が一定間隔の格子状を成して固定されているので、本体フレーム２０の左右部分で極めて強化された構造体を構成している。
【００２７】
このような構成によれば、五徳１６と同様に機械的強度の高い支持手段としての五徳を実現でき、また、本体フレーム２０に対し、プレス加工で梁部３４を固着した後、爪部３６、５０を同様にプレス加工で取り付けることができ、製造工程の簡略化とともに、溶接による固着以上の強度を実現することができる。
【００２８】
本発明の五徳には、次のような変形例がある。
ａ．実施形態では、１つの本体フレームに対し、２枚の梁部を取り付けたが、１枚又は３枚以上の梁部で構成してもよい。
ｂ．爪部は、６枚構成としたが、５枚以下又は７枚以上で構成してもよい。
ｃ．爪部や梁部を本体フレームに機械的に結合したが、一部に溶接を併用してもよい。
ｄ．五徳１６は、２つの火口を包含するような形態としたが、火口毎に分割した構成としてもよい。
ｅ．本発明は、調理器としてビルトインコンロを例に取って説明したが、テーブル設置型等の各種の調理装置の火口上に設置する五徳に適用できることは言うまでもない。
【００２９】
【発明の効果】
以上説明したように、本発明によれば、次の効果が得られる。
ａ．本体フレームに取付部材を第１及び第２の凹部の噛み合わせにより、機械的に結合したので、機械的に強固な五徳を実現でき、従来の溶接を用いたものに比較し、製造工程の簡略化とともに、溶接電極の管理等が不要となり、歩留りを高めることができる。
ｂ．結合させた本体フレームと取付部材における第１及び第２の凹部の対向面部間に間隙を設けたので、この間隙が機械的な歪みを吸収する緩衝部として機能し、機械的ながたつきを防止して、調理用容器を安定した状態で支持でき、寿命の長い五徳を提供できる。
ｃ．第１又は第２の凹部の何れか一方を平行壁面で形成し、他方の被着面部を凹凸面としてなるので、両者の加締め強度を高めることができ、強固な五徳を実現できる。
ｄ．本発明の五徳の製造方法によれば、打ち抜き加工やプレス加工のみで五徳を製造でき、溶接による手数がなく、従来必要としていた溶接電極の管理等が削減できる結果、製造コストの低減化とともに、強固な五徳を安価に製造できる。
ｅ．取付部材を第１及び第２の部材に分け、本体フレームに第１の部材を固定して形状維持を実現した後、第２の部材を固定するので、製造工数の削減とともに、形状精度の高い五徳を提供できる。
ｆ．強固な五徳を使用した安全性が高く、使い勝手の良い調理器を実現することができる。

[0019]
As shown in FIGS. 13 and 14, the main body frame 20 is provided with a groove portion 42 as a first recess in a portion where the beam portion 34 and the claw portions 36 and 38 are fixed. A groove portion 42 is formed at a location where the claw portion 40 is fixed. The beam portion 34 is formed in a U shape as shown in FIGS. 7, 8, and 10, and as shown in FIGS. 13 and 14, a fixing portion 44 for the main body frame 20 is formed on both ends. The fixed portion 44 is formed with a deep groove portion 46 as a second concave portion.
[0020]
The groove portion 42 on the main body frame 20 or the beam portion 34 side is formed in a rectangular shape having a width and depth equivalent to the thickness of the plate material constituting the main body frame 20 or the beam portion 34, whereas on the fixed portion 44 side.

Therefore, the width d of the opening of the groove 46 is set to be slightly larger than the thickness of the material, and the corner is formed on the curved surface 46d.
[0021]
Next, a manufacturing method of the first virtues 16 will be described. A main body frame 20 shown in FIG. 9 is formed by cutting and forming a metal strip having a constant width and welding the ends. In the main body frame 20, a groove portion 42 is formed by machining such as cutting or punching at a position where the beam portion 34 and the claw portions 36 and 38 are attached. Further, by punching a metal plate material similar to that of the main body frame 20, two beam portions 34 and ten claw portions 36, 38, 40 are formed. In that case, the claw portions 36, 38, and 40 are formed with the groove portion 42, the groove portion 46, or both.
[0022]
For assembling Gotoku 16, a press machine is used, and a die as a jig for supporting the main body frame 20 is used. The main body frame 20 is installed on the mold with the groove 42 side facing upward, and as a first stage processing, the two beam portions 34 are positioned and temporarily fixed to the main body frame 20. In that case, the groove portion 42 of the fixing portion 44 of the beam portion 34 is engaged with the groove portion 42 of the main body frame 20 so that they are orthogonal to each other. When arranged in this manner, the groove portion 46 is wider than the thickness of the material of the main body frame 20, so that the beam portion 34 is accurately positioned on the main body frame 20 and is in a vertical state. When press working, that is, compression working is performed in this state, the fixing portion 44 of the beam portion 34 is lowered and crimped to the main body frame 20 side, and the main body frame 20 and the two beam portions 34 are firmly in place. It becomes a fixed state. As a result, between the flat portions 28 of the main body frame 20, the two beam portions 34 having a predetermined interval are connected in a bridging state. Therefore, the mechanical strength of the main body frame 20 is more enhanced by the connection of the beam portions 34. It will be solid.
[0023]
Next, the claw portions 36 and 38 are temporarily fixed to the main body frame 20, the claw portion 40 is temporarily fixed to the beam portion 34, and the beam portion 34 is attached to the main body frame 20 by performing compression processing in this state. Similarly to the fixing, the groove portion 46 is engaged with the groove portion 42, so that the main body frame 20 and the claw portions 36 and 38, and the beam portion 34 and the claw portion 40 can be firmly coupled. Between the beam portions 34, the flat portions 41 of the two claw portions 40 are coupled in a bridging state, and the two beam portions 34 and the flat portions 41 of the two claw portions 40 are latticed. Thus, an extremely strong shape maintaining function is realized at the center of the main body frame 20, and an extremely strong structure is obtained.
[0024]
15 and 16 show the coupling state of the main body frame 20 and the beam portion 34 or the claw portions 36 and 38, the beam portion 34 and the claw portion 40, and the bottom surface 43 of the groove portion 42 and the ceiling surface of the groove portion 46. A gap 48 having a slight width t is formed between the gap 46a. That is, a gap 48 is provided in the height direction between the coupling portions between the main body frame 20 and the beam portion 34 or the claw portions 36 and 38, and between the coupling portions between the beam portion 34 and the claw portion 40. In addition, a gap 48 is provided in the height direction. By adopting a configuration in which such a gap 48 is provided, the bottom surface of the groove 42 is fixed to the main body frame 20 or the beam 34 and the claw portions 36 and 38 as mounting members and the caulking and fixing of the beam 34 and the claw 40. 43 and an unnecessary stress in the innermost portion of the groove portion 46 near the ceiling surface 46a, that is, a stress that enlarges the interval between the groove portions 42 and 46 set to a constant width more than necessary. It is possible to suppress the action between them, the elasticity of the material is fully functioned, and a strong mechanical connection can be achieved. Further, such a gap 48 functions as a buffer portion that absorbs mechanical strain against the load and heat acting on the claw portions 36 to 40, and can prevent mechanical rattling. A product that can withstand the use of time can be realized.
[0025]
Further, the claw portions 36 and 38 constitute a cantilever with respect to the main body frame 20, but the fixing portions 44 of the claw portions 36 and 38 mesh with each other in the width direction of the main body frame 20, The coupling state is extremely strong, can achieve mechanical strength exceeding the fixing by conventional welding, and can achieve uniform load distribution by the plurality of claw portions 36, 38, 40, so that cooking with a considerable weight is possible. The container can be supported in a stable state.
[0026]
Next, the second virtues 18 will be described. Unlike the virtues 16, the virtues 18 support the cooking container with a single crater 8 in the center, and the basic configuration is the same as the virtues 16. That is, the main body frame 20 is similar to Gotoku 16 only with a narrow width in the front-rear direction. In the five virtues 18, two beam portions 34 are installed with the crater 8 in between. Then, the two claw portions 36 and the four claw portions 50 are fixed, and the tip end side is disposed with an angular interval of 60 degrees, for example. In this embodiment, a pair of fixing portions 44 are provided corresponding to the main body frame 20 and the beam portion 34 on the flat portion 52 side of the claw portion 50, and the groove portion 46, the main body frame 20 and the beam portion 34 on the fixing portion 44 side. The groove portion 42 is coupled to each other, and a gap 48 is formed between the bottom surface 43 of the groove portion 42 and the ceiling surface 46a of the groove portion 46 as in the case of Gotoku 16. In this embodiment, the flat portions 52 of the two claw portions 50 are fixed between the left and right beam portions 34 and the flat portion 32 of the main body frame 20 in a lattice pattern with a constant interval. The left and right portions of the main body frame 20 constitute a very reinforced structure.
[0027]
According to such a configuration, the virtue as a support means having high mechanical strength can be realized similarly to the virtue 16, and after fixing the beam portion 34 to the main body frame 20 by pressing, the claw portions 36, 50 can be similarly attached by press work, and the strength more than the fixation by welding can be realized with simplification of the manufacturing process.
[0028]
The virtues of the present invention have the following modifications.
a. In the embodiment, two beam portions are attached to one main body frame, but may be configured by one or three or more beam portions.
b. Although the nail | claw part was comprised with 6 sheets, you may comprise 5 sheets or less or 7 sheets or more.
