Description

【０００１】
【発明の属する技術分野】
この発明は、パチンコ機（雀球機、アレンジボール機等も含む）のような弾球遊技機やスロットマシン等の遊技機に関する。
【０００２】
【従来の技術】
例えば、パチンコホール等の遊技場に設置された島設備に配列されて使用される遊技機は、その木製の枠体（外枠、外枠体、木枠等とも呼ばれる場合もある）において島設備に釘打ちによって固定されるのが一般的である。
近年、自然環境保護等を考慮し、木製の枠体を合成樹脂製の枠体に変更すること、すなわち、枠体を合成樹脂材料によって一体成形することが提案されている。
【０００３】
【発明が解決しようとする課題】
ところで、単一の合成樹脂材料によって枠体を一体成形した場合、その枠体の各部分において必要とされる物理的特性、例えば、強度、剛性、耐久性等に対応して前記枠体の各部分を構成することが困難となる場合があった。
この発明の目的は、前記問題点に鑑み、必要とされる物理的特性に対応して枠体の各部分を容易に形成することができる枠体を備えた遊技機を提供することである。
【０００４】
前記目的を達成するために、第１の発明は、請求項１に記載のとおりの構成を要旨とする。つまり、遊技機用島設備に固定可能な遊技機であって、
木質系粉末材料と合成樹脂材料との混合材料によって略矩形状に射出成形によって一体成形される枠体を備え、
前記遊技機は、前記枠体により前記遊技機用島設備に固定可能であり、
前記枠体は、
上枠部と、
左右の両側枠部と、
下枠部と
を備え、
前記上枠部と前記下枠部とが釘打ち可能領域に設定されており、前記枠体は、前記遊技機用島設備に対し、前記上枠部と前記下枠部においてそれぞれ釘打ちによって固定され
前記左右の両側枠部は、前記釘打ち可能領域としての上枠部と下枠部よりも強度が大きい高強度領域に設定されており、
前記釘打ち可能領域としての前記上枠部と前記下枠部は、木質系粉末材料と合成樹脂材料との混合比率において木質系粉末材料の混合比率が比較的大きい混合材料によって形成され、
前記高強度領域としての前記左右の両側枠部は、木質系粉末材料と合成樹脂材料との混合比率において木質系粉末材料の混合比率が比較的小さい混合材料によって形成されることを特徴とするものとしても良い。したがって、枠体の各部分において、合成樹脂材料と他の材料との混合材料の混合比率がそれぞれ異なることで、枠体の各部分に対し、それぞれ必要とされる物理的特性に対応する特性をもたせることができる。これによって、必要とされる物理的特性に対応する特性を各部分にもつ枠体を容易にかつ一体状に形成することができる。
【０００５】
また、第２の発明は、請求項３に記載のとおりの構成を要旨とする。遊技機用島設備に固定可能な遊技機であって、
合成樹脂材料と他の材料との混合材料によって略矩形状に射出成形によって一体成形される枠体を備え、
前記遊技機は、前記枠体により前記遊技機用島設備に固定可能であり、
前記枠体は、
上枠部と、
左右の両側枠部と、
下枠部と
を備え、
前記上枠部と前記下枠部とが釘打ち可能領域に設定されており、前記枠体は、前記遊技機用島設備に対し、前記上枠部と前記下枠部においてそれぞれ釘打ちによって固定され
前記左右の両側枠部は、前記釘打ち可能領域としての上枠部と下枠部よりも強度が大きい高強度領域に設定されており、
前記釘打ち可能領域としての前記上枠部と前記下枠部は、木質系粉末材料と合成樹脂材料との混合材料によって形成され、
前記高強度領域としての前記左右の両側枠部は、ガラス繊維からなる強化材と、合成樹脂材料との混合材料によって形成されることを特徴とするものとしても良い。
したがって、枠体の各部分において、合成樹脂材料と他の材料との複数種類の混合材料によって、必要とされる物理的特性に対応する特性をもつ枠体の各部分を容易に形成することができる。
【０００６】
第３の発明は、請求項１に記載のとおりの構成を要旨とする。したがって、遊技機の島設備に釘打ちによって枠体を固定する場合、枠体を、その釘打ち可能領域において釘打ちして容易に固定することができ、その釘打ち可能領域以外の高強度領域によって枠体の強度を保持することができる。
【０００７】
第４の発明は、請求項１に記載のとおりの構成を要旨とする。したがって、遊技機の島設備に釘打ちによって枠体を固定する場合、枠体の上枠部と下枠部のうち、少なくとも一方の枠部を釘打ち可能領域として釘打ちして容易に固定することがでる。また、枠体の左右の両側枠部のうち、少なくとも一方に側枠部を前記釘打ち可能領域よりも強度が大きい高強度領域として、枠体の強度を保持することができる。
【０００８】
第５の発明は、請求項１に記載のとおりの構成を要旨とする。したがって、枠体を形成する混合材料として、合成樹脂材料と、木質系粉末材料との混合材料が用いられることによって、合成樹脂材料のみで成形した場合に比較して、枠体を成形した後の材料収縮率を低く押さえることができる。この結果、枠体の各部に対しヒケの発生を軽減することができ、ヒケによる見栄えの悪化も防止することができる。また、木質系粉末材料の混入によって、枠体は釘打ちやビス締め等にも充分に耐えることができる。このため、遊技機の島設備に対し、枠体の一部を釘打ちによって固定する場合においても、枠体の釘打ち部分にひび割れや亀裂が発生する不具合も生じない。遊技機用島設備に遊技機を固定するための枠体の成形方法であって、
前記枠体は、木質系粉末材料と合成樹脂材料との混合材料の射出成形によって略矩形状に一体成形され、
前記枠体は、
上枠部と、
左右の両側枠部と、
下枠部と
を備え、
前記上枠部と前記下枠部とが釘打ち可能領域に設定されており、前記枠体は、前記遊技機用島設備に対し、前記上枠部と前記下枠部においてそれぞれ釘打ちによって固定され
前記左右の両側枠部は、前記釘打ち可能領域としての上枠部と下枠部よりも強度が大きい高強度領域に設定されており、
前記釘打ち可能領域としての前記上枠部と前記下枠部は、木質系粉末材料と合成樹脂材料との混合比率において木質系粉末材料の混合比率が比較的大きい混合材料によって形成され、
前記高強度領域としての前記左右の両側枠部は、木質系粉末材料と合成樹脂材料との混合比率において木質系粉末材料の混合比率が比較的小さい混合材料によって形成され、
前記釘打ち可能領域を形成する合成樹脂材料と、前記高強度領域を形成する合成樹脂材料とを互いに溶融温度が略同一である合成樹脂材料とし、
前記枠体の成形方法は、
前記釘打ち可能領域と、前記高強度領域とのうち、一方の領域に含まれる枠部を射出成形する第一の工程と、
前記第一の工程の後で、前記一方の領域に含まれる枠部を別の成形型内にセットしてから他方の領域に含まれる枠部を射出成形する第二の工程と
を含むことで、前記釘打ち可能領域と、前記高強度領域との境界部分が相互に溶融して一体化し接合し、枠体を成形するものとしても良い。
【０００９】
【発明の実施の形態】
（実施の形態１）
この発明の実施の形態１を図面にしたがって説明する。
パチンコ機を正面側から視た斜視図で表した図１５、外枠体に対し基盤を開いて正面側から視た斜視図で表した図１６、及び外枠体に対し基盤を開きかつその基盤に対し裏セット部材を開いた状態を斜視図で表した図１７において、遊技機としてのパチンコ機１は、遊技機の島設備に対し釘打ちによって固定される略矩形状の枠体としての外枠体５０と、その外枠体５０の前側に開閉可能に装着されかつ遊技機本体として機能する基盤１０（前枠とも呼ばれている）とを主体として構成されている。
基盤１０は、遊技盤１３前面の略全体を露出する開口部を有するとともに、その裏面の開口部周縁に沿って支持枠１１が設けられている。支持枠１１には遊技盤１３が着脱可能に嵌込まれ、その遊技盤１３裏面の周縁部が後述する裏セット部材２０に押さえられて支持されている。
【００１０】
また、図１７に示すように、基盤１０の裏面側には、その支持枠１１の片側の枠部において、裏セット部材２０が開閉可能に組み付けられている。この裏セット部材２０の裏面側には、その上部から下部に向けて球タンク、タンクレール、球払出装置等が装着されている。
また、図１７に示すように、基盤１０の支持枠１１には、裏セット部材２０を閉じ状態に保持するための複数の締付具１９が組み付けられている。そして、まず、支持枠１１に遊技盤１３が嵌込まれ、次に、裏セット部材２０が閉じられ、その裏セット部材２０が複数の締付具１９によって閉じ状態に保持されることで、基盤１０の支持枠１１に裏セット部材２０を介して遊技盤１３が固定状態でされるようになっている。また、これとは逆に、複数の締付具１９を外して裏セット部材２０を開いた状態のもとで、基盤１０の裏面側からその支持枠１１に対し遊技盤１３が着脱されるようになっている。
【００１１】
図１６に示すように、遊技盤１３の前面には平帯状のレール１６が装着され、そのレール１６の内側において遊技領域１５が区画されている。
また、レール１６は、その片側に内側レール部と外側レール部とを有し、これら内外のレール部の間には発射案内路１７が構成されている。また、遊技盤１３の遊技領域１５内には、遊技構成部材としての各種の入賞装置、役物装置、図柄表示装置、アタッカ装置、ゲート口、風車器、誘導釘等（図示しない）が配設されている。そして、発射ハンドル装置２３を操作して発射ハンマーを作動することによって発射位置にある球（パチンコ球）がレール１６の発射案内路１７に案内されて遊技領域１５に打ち出されるようになっている。また、遊技盤１３の裏面側には、その遊技盤１３に装着された各種の入賞装置、役物装置、図柄表示装置、アタッカ装置等の遊技構成部材（図示しない）を制御する制御ボックス装置（図示しない）が装着されている。
【００１２】
また、図１７に示すように、基盤１０裏面の自由端側には、上下二つの基盤施錠用フック２１が上下方向にスライド可能に組み付けられ、外枠体５０に対し基盤１０が閉じられたときには、その基盤施錠用フック２１が外枠体５０に固定の係合部材９５に係合し、これによって外枠体５０に対し基盤１０が閉じ状態に施錠されるようになっている（図１参照）。
図１５と図１６に示すように、基盤１０の前側には、表枠３０（ガラス扉、ガラス枠等とも呼ばれている）がその一側に配設されたヒンジ機構によって開閉可能に装着されている。この表枠３０には、遊技盤１３の遊技領域１５を透視可能な略円形の開口窓３１が形成されている。そして、表枠３０の裏面側には、開口窓３１を透視可能に塞ぐ前後二枚のガラス板を保持するガラス枠３３が設けられている。
また、基盤１０の前側には、表枠３０の下方に隣接して下板４０が開閉可能に装着され、その下板４０の前面には上皿４３が設けられている。
また、基盤１０の前面には、その下板４０の下方に位置して球発射用の発射ハンドル装置２３や下皿２４等が組み付けられている。
【００１３】
図１と図２に示すように、枠体としての外枠体５０は、木質系粉末材料（例えば、杉材、檜材、松材、ラワン材、チーク材等の単一又は複合の木質系粉末材料）と、合成樹脂材料（例えば、ポリプロピレン、ポリエチレン、ＡＢＳ樹脂等の熱可塑性合成樹脂材料）とが所要とする混合比率で混合された混合材料による射出成形によって一体成形されている。そして、外枠体５０は、上枠部５１、左右の両側枠部６０、６１及び下枠部７０を一体に備えて略矩形枠状に構成されている。
【００１４】
また、この実施の形態１において、図１と図２に示すように、外枠体５０の上枠部５１と左右の両側枠部６０、６１とがなす角部５４、５６の内側部は、射出成形によってアール面５５、５７に形成され、これによって角部５４、５６が肉厚に形成されて強度が高められるとともに、その角部５４、５６に作用する荷重をアール面５５、５７において分散して受けるようになっている。また、左右の両側枠部６０、６１の前面下部、及び下枠部７０の前部上面にわたって、基盤１０の下端面を受け支える下受板７５が一体成形されている。
このように、外枠体５０の上部左右の両角部５４、５６がアール面５５、５７によって補強され、下部左右の両角部が下受板７５によって補強されることで、外枠体５０を長期間にわたって所要とする矩形の形状に維持できるようになっている。
【００１５】
前記したように、射出成形によって一体成形された外枠体５０において、その各角部のうち、少なくとも１つの角部は略中実状に形成されている。この実施の形態１において、外枠体５０の上部左右の両角部５４、５６がそれぞれ略中実状に形成されている。
また、外枠体５０の上下の枠部５１、７０と左右の両側枠部６０、６１のうち、少なくとも一辺をなす枠部の長手方向には、肉抜き部とリブとがそれぞれ設けられている。この実施の形態１において、外枠体５０の上枠部５１と下枠部７０の長手方向（横方向）には、肉抜き部５２、７６とリブ５３、７７とがそれぞれ形成され、左右の両側枠部６０、６１の長手方向（縦方向）には、肉抜き部６２、６３とリブ６４、６５とがそれぞれ形成されている。
【００１６】
また、外枠体５０の上枠部５１、下枠部７０及び左右の両側枠部６０、６１の各部の肉抜き部５２、７６、６２、６３は、これら各枠部の板厚内において、外枠体５０の裏面側から奥行き方向に向けて凹設されている。さらに、上枠部５１、下枠部７０及び左右の両側枠部６０、６１の各リブ５３、７７、６４、６５は、各部の肉抜き部５２、７６、６２、６３をそれぞれ区画するようにして各部の肉抜き部５２、７６、６２、６３の相対する内壁面の間に跨って設けられている。
また、各部の肉抜き部５２、７６、６２、６３は、外枠体５０の上枠部５１、下枠部７０及び左右の両側枠部６０、６１の各枠部の厚さ方向の寸法よりもこれら各枠部の長手方向の寸法が適宜に大きく設定されている。すなわち、図１〜図６に示すように、各部の肉抜き部５２、７６、６２、６３は、各枠部の長手方向に長い長穴状に形成されている。
【００１７】
また、図１に示すように、外枠体５０上部の略中実状をなす一方の角部５４には、開閉部材としての基盤１０を開閉可能に支持するための上下一対のヒンジ部材のうち、上側のヒンジ部材８０がビスや釘によって取り付けられている。
このヒンジ部材８０は、金属製で、例えば、鉄板等の金属板の曲げ加工等によって形成されている。そしてヒンジ部材８０は、補強部材としても機能するものであり、角部５４の上面に沿う上板部８１と、角部５４の外側面に沿う側板部８２とを備えて略Ｌ字状に形成されている。そして、外枠体５０の一方の角部５４に対し、ヒンジ部材８０の上板部８１及び側板部８２を通してビスがねじ込まれたり、あるいは釘が打ち込まれることによって、外枠体５０の一方の角部５４にヒンジ部材８０が強固に固定されるようになっている。
また、ヒンジ部材８０の上板部８１の前縁には、ヒンジ片８３が前方に向けて略水平上に延出されている。このヒンジ片８３の先端部寄り部分には、基盤１０の上側のヒンジ部材に設けられたヒンジピンが挿脱可能に嵌挿されるヒンジ孔を有するヒンジ筒８４が一体に設けられている。
【００１８】
また、この実施の形態１において、上下一対のヒンジ部材のうち、下側のヒンジ部材８５は、外枠体５０の一方の側枠部６０の下部に固定されている。
図１、図２及び図５に示すように、下側のヒンジ部材８５は、金属製で、例えば、鉄板等の金属板の曲げ加工等によって形成されている。この下側のヒンジ部材８５は、側枠部６０の内面に沿う側板部８６と、その側板部８６の下端から下受板７５の上面に沿って折り曲げられた下板部８７とを備えて略Ｌ字状に形成されている。そして、外枠体５０の一方の側枠部６０の下部外側面に凹設された溝７３に配置された当て板８９とヒンジ部材８５の側板部８６との間に一方の側枠部６０を間に挟んで、これら当て板８９と側板部８６とをボルト・ナット、あるいはリベット等によって結合することによって、外枠体５０の一方の側枠部６０の下部にヒンジ部材８５が強固に固定されるようになっている。
また、ヒンジ部材８５の下板部８７の前縁には、基盤１０の下側のヒンジ部材に設けられたヒンジ孔に挿脱可能に嵌挿されるヒンジピン８８が上方に向けて一体状に突設されている。
【００１９】
また、この実施の形態１において、外枠体５０の他方の側枠部６０内面の上下部には、開閉部材としての基盤１０の基盤施錠用フック２１に係脱可能に係合して基盤１０を閉じ状態に施錠するための係合片を有する係合部材９５が、その基片においてビス等によって固定されている。この係合部材９５は、金属製で、例えば、鉄板等の金属板の曲げ加工等によって形成されている。
【００２０】
また、この実施の形態１において、外枠体５０の上部左右の両角部５４、５６のうち、略中実状をなす他方の角部５６には、鉄板等の金属板の曲げ加工等によって形成されるインサート用補強部材９０、又は圧入用補強部材１００が埋め込み状に設けられている。
すなわち、外枠体５０を一体成形すると同時に、その外枠体５０の他方の角部５６にインサート用補強部材９０をインサートする場合、予め、成形型内にインサート用補強部材９０が位置決めされてセットされる。その後、木質系材料と合成樹脂材料との混合材料（溶融状態の混合材料）が成形型のキャビティ内に射出されることで、外枠体５０が成形されると同時に、その外枠体５０の他方の角部５６にインサート用補強部材９０がインサートされて一体化する。
【００２１】
図８〜図１０に示すように、インサート用補強部材９０は、角部５６の一辺（上枠部５１に延びる部分）に沿う第１の翼片９１と、角部５６の他辺（側枠部６１に延びる部分）に沿う第２の翼片９２とをそれぞれ備えて略Ｌ字状に形成をなしている。
また、所定の使用期間を経たパチンコ機１を解体する際に、外枠体５０からインサート用補強部材９０を分離し易くするために、インサート用補強部材９０の第１、第２の各翼片９１、９２の所定位置には、取外用の工具が差し込み可能な取外孔９３、９４が形成されている。
一方、外枠体５０の角部５６裏面の所定位置には、各取外孔９３、９４に取外用工具を差し込むための差込溝１１１、１１２が、外枠体５０の成形と同時にそれぞれ形成されている。
【００２２】
また、外枠体５０を成形した後、その角部５６に圧入用補強部材１００を圧入によって埋込状に設ける場合、外枠体５０を成形するときに、その角部５６の中実部の所定位置に圧入用補強部材１００に対応する嵌込み溝１２０が外枠体５０の成形と同時にそれぞれ形成される。
そして、外枠体５０を成形した後、その嵌込み溝１２０に対し圧入用補強部材１００が圧入によって嵌込まれることで、外枠体５０の角部５６に圧入用補強部材１００が埋め込み状に固定される。
【００２３】
図１１〜図１４に示すように、圧入用補強部材１００は、外枠体５０の角部５６の一辺（上枠部５１に延びる部分）に沿う第１の翼片１０１と、角部５６の他辺（側枠部６１に延びる部分）に沿う第２の翼片１０２とを備えて略Ｌ字状に形成をなしている。
また、第１、第２の各翼片１０１、１０２の所定位置には、弾性変形可能な係止爪１０３、１０４が切り込み孔によって切起状に形成されている。そして、外枠体５０の角部５６の嵌込み溝１２０に対し圧入用補強部材１００が圧入によって嵌込まれることで、その第１、第２の各翼片１０１、１０２の係止爪１０３、１０４が嵌込み溝１２０の内壁面に弾性的にくい込み、これによって外枠体５０の角部５６に圧入用補強部材１００が埋め込み状に固定されるようになっている。
また、所定の使用期間を経たパチンコ機１を解体する際に、外枠体５０から圧入用補強部材１００を分離し易くするために、圧入用補強部材１００の第１、第２の各翼片１０１、１０２の上縁部には、引抜片１０５、１０６が折り曲げ形成されている。
一方、外枠体５０の角部５６裏面の所定位置には、圧入用補強部材１００の各引抜片１０５、１０６に対し引抜用工具を差し込むための差込溝１２１、１２２が、外枠体５０の成形と同時に形成されている。
【００２４】
さて、外枠体５０の各部分（各枠部やその各枠部の所要部分）において、必要とされる物理的特性（例えば、強度、剛性、耐久性等）に対応して外枠体５０の各部分を構成する木質系粉末材料（例えば、杉材、檜材、松材、ラワン材、チーク材等の単一又は複合の木質系粉末材料）と、合成樹脂材料（例えば、ポリプロピレン、ポリエチレン、ＡＢＳ樹脂等の熱可塑性合成樹脂材料）との混合比率がそれぞれ異なっている。
例えば、遊技機の島設備に対し外枠体５０が、その上枠部５１と下枠部７０においてそれぞれ釘打ちによって固定される場合、これら上枠部５１と下枠部７０とが釘打ち可能領域に設定される。一方、左右の両側枠部６０、６１及び角部５４、５６は、前記釘打ち可能領域としての上枠部５１と下枠部７０よりも強度が大きい高強度領域に設定される。
このようにして外枠体５０の各部分が釘打ち可能領域と高強度領域にそれぞれ設定された場合、釘打ち可能領域としての上枠部５１と下枠部７０は、木質系粉末材料と合成樹脂材料との混合比率（重量比）において５対５〜６対４程度の混合比率をもつ混合材料によって形成される。
また、高強度領域としての左右の両側枠部６０、６１及び角部５４、５６は、木質系粉末材料と合成樹脂材料との混合比率（重量比）において４対６程度の混合比率をもつ混合材料によって形成される。
【００２５】
上述したように構成されるこの実施の形態１に係るパチンコ機１において、枠体としての外枠体５０を、木質系粉末材料と合成樹脂材料との混合材料による射出成形によって略矩形枠状に一体成形することによって、外枠体５０を容易に製造することができる。
また、木質系粉末材料の混入によって、材料収縮が小さく押さえられる。これによって、外枠体５０の各枠部にヒケ（凹凸の歪み）が発生することを防止することができ、ヒケによる見栄えの悪化が生じない。
また、木質系粉末材料の混入によって、外枠体５０は釘打ちやビス締め等にも充分に耐えることができる。このため、遊技機の島設備に対し、外枠体５０の上枠部５１と下枠部７０とのうち、少なくとも一方の枠部を釘打ちによって固定する場合においても、その枠部の釘打ち部分にひび割れや亀裂が発生する不具合も生じない。
【００２６】
特に、この実施の形態１において、釘打ち可能領域としての上枠部５１と下枠部７０は、木質系粉末材料と合成樹脂材料との混合比率（重量比）において５対５〜６対４程度の混合比率、すなわち、木質系粉末材料の混合比率が比較的大きい混合材料によって形成される。このため、遊技機の島設備に対し、外枠体５０の上枠部５１と下枠部７０とのうち、少なくとも一方の枠部を釘打ちによって固定する場合、その枠部の釘打ち部分にひび割れや亀裂が発生する不具合をより一層確実に防止することができる。
また、高強度領域としての左右の両側枠部６０、６１及び角部５４、５６は、木質系粉末材料と合成樹脂材料との混合比率（重量比）において４対６程度の混合比率、すなわち、木質系粉末材料の混合比率が比較的小さい混合材料によって形成される。このため、左右の両側枠部６０、６１及び角部５４、５６を高強度に形成することができる。
【００２７】
また、外枠体５０の各部を構成する混合材料のうち、合成樹脂材料を同質の合成樹脂材料とすることで、混合比率が異なる混合材料の射出成形のための溶融温度も略同一となり、成形性が悪化される不具合が生じない。
また、釘打ち可能領域としての上枠部５１、下枠部７０と、高強度領域としての側枠部６０、６１（角部５４、５６）とのうち、一方の枠部を射出成形した後、その一方の枠部を別の成形型内にセットしてから他方の枠部を射出成形して外枠体５０を構成することも可能である。
このような場合においても、釘打ち可能領域としての上枠部５１、下枠部７０と、高強度領域としての側枠部６０、６１（角部５４、５６）との境界部分が相互に溶融して一体化し、強固に接合する。このため、前記境界部分において外枠体５０が損傷される不具合も防止することができる。
【００２８】
また、この実施の形態１において、外枠体５０の角部５４、５６を略中実状とすることで、その角部５４、５６の強度を所要とする強度に維持することができるとともに、木質系粉末材料の混入によって、略中実状の角部５４、５６に対するヒケの発生を軽減することができ、ヒケによる見栄えの悪化を防止することができる。
また、外枠体５０の上枠部５１、下枠部７０、及び左右の両側枠部６０、６１の少なくとも一辺をなす枠部、この実施の形態１では、上枠部５１、下枠部７０、及び左右の両側枠部６０、６１に肉抜き部５２、７６、６２、６３を設けることによって、軽量化を図ることができるとともに、材料を節減することができる。
【００２９】
また、この実施の形態１において、外枠体５０の上枠部５１、下枠部７０、及び左右の両側枠部６０、６１の長手方向に対し、肉抜き部５２、７６、６２、６３と、リブ５３、７７、６４、６５とをそれぞれ交互に設けることで、肉抜き部５２、７６、６２、６３が原因となる強度劣化をリブ５３、７７、６４、６５によって防止することができる。言い換えると、外枠体５０の上枠部５１、下枠部７０、及び左右の両側枠部６０、６１の長手方向に対する、肉抜き部５２、７６、６２、６３の存在割合を高くしても、リブ５３、７７、６４、６５によって強度劣化を防止することができるため、軽量化や材料節減において効果が大きい。
【００３０】
また、この実施の形態１において、外枠体５０の上枠部５１、下枠部７０、及び左右の両側枠部６０、６１の各肉抜き部５２、７６、６２、６３は、同外枠体５０の裏面側から奥行き方向に向けて凹設されているため、外枠体５０の前面に各肉抜き部５２、７６、６２、６３が隠蔽された状態となり、肉抜き部５２、７６、６２、６３による見栄えの悪化が生じない。
また、外枠体５０の上枠部５１、下枠部７０、及び左右の両側枠部６０、６１の各リブ５３、７７、６４、６５は、各肉抜き部５２、７６、６２、６３を区画するようにして、これら各肉抜き部５２、７６、６２、６３の内壁面の間に跨って設けられている。このため、上枠部５１、下枠部７０、及び左右の両側枠部６０、６１が肉抜き部５２、７６、６２、６３において不測に拡開変形することを防止することができる。
【００３１】
