【従来の技術】
パチンコ機においては、遊技盤１に内レール６と外レール７等のガイドレールを装着し、該ガイドレールに囲まれた遊技領域８の内側に、アタッカー１４、入賞口１１、始動口１３、風車９、通過チャッカー１５、サイド表示ランプ１０、センターケース１２等の遊技部品を配置している。
【０００３】
従来、遊技機の遊技盤１においては、ベニヤ等の遊技基板２の上に装飾シート５を貼着した遊技盤面上に夫々の役目を持つ数種の遊技部品が取付けられるのであるが、各遊技部品が遊技盤１に対応するように挿入可能な遊技部品取付孔３が配設され、そして螺子により遊技盤１に遊技部品が固定されている。もしくは、遊技部品取付孔３に対応するよう遊技部品の主要箇所に適宜配設された弾性を有す図１１のセンターケース１２の斜視図にあるような外向きの固定爪部材２３を具備し、遊技部品取付孔３の前面から嵌合させると圧入により該固定爪部材２３が内向きに弾性変形し、遊技盤１に設けられた係止部２５において被係止部と遊技基板２の裏面で固定されている（例えば、特許文献１参照。）。また、遊技基板２に配設された遊技部品取付孔３の一部を拡径して段差部分を付設し、該段差部分に固定爪部材２３を配設した遊技部品を嵌合するようにしている（例えば、特許文献２参照。）。
【０００４】
そして、遊技盤１に配設される図柄に関してであるが、遊技基板２の前面に二像またはそれ以上の視差のある画像を写した立体視用合成画像シート１６を接着剤１９により遊技基板４に貼り付け、該立体視用合成画像シート１６の前面に該立体視用合成画像シート１６レンズ１８のピッチＰを合わせたレンチキュラー板１７を接着剤４により貼り付け、遊技者に平面的な画像を立体的に見せることがしばしば行われている（例えば、特許文献３参照。）。

【発明が解決しようとする課題】
しかし、遊技部品の取付構造にあっては、従来では遊技盤の前面から螺着するという方法が数多くとられていた為、取付作業に時間がかかっていた。また、遊技部品を固定する位置決めにも熟練者でないと取付穴内でずれたりしてしまっていた。そして、遊技部品の圧入による固定に関しても、従来では、係止部分が遊技基板裏面から突出して固定する形をとっていた為、遊技球を誘導する一体成形された枠体である集合盤の着脱作業においても多大な困難をきたしていた。
【０００７】
本発明は、かかる従来の課題に鑑み提案されたもので、集合盤に接触することなく遊技盤へ遊技部品の固定が為せるとともに、安価での製作を可能とする遊技機の遊技盤を開発することを目的としている。

図１２において、１１ａは入賞口１１の取付孔であり、該入賞口１１の取付孔１１ａに入賞口１１の固定爪部材２３を遊技盤１の前方より切除部２６の後方へ圧入すると、その通過時に該固定爪部材２３が内側へ弾性変形し、通過後元の状態へと復帰し、固定爪部材２３と固定溝穴２２とが係止部２５において圧入固定される。尚、圧入固定される際に固定爪部材２３は遊技基板２の裏面にへ突出せずに、該固定爪部材２３の先端は固定溝穴２２内に位置する。
