バックライト装置20は、表側に放電管21(本発明のランプに該当する)が配置されるシャーシ22を備えている。シャーシ22は金属製であって、平板状をなす底板22Aと、底板22Aの周縁から表側へ立ち上がる周板22Bとにより構成され、全体として表側へ開口する浅皿状をなしている。シャーシ22の周板22B、ベゼル12およびフレーム13には、図3に示すように、固定孔23が表裏方向に貫通して形成されており、この固定孔23に図示しないネジを挿通して締め付けることで、シャーシ22、ベゼル12およびフレーム13は一体化されている。
また、一対のアーム部31Aの先端部(保持突起31Bよりも表側の端部)の対向面は、先端に向かって互いの間隔が少しずつ広がる傾斜をなす傾斜面31Cとされている。この傾斜面31Cにより、放電管21の取り付け動作が案内される。
係止爪37の表側の面は、シャーシ22の裏面に係止する係止面38とされている。係止面38は、ベース部33の裏面と略平行(係止脚部32Bの軸方向に対して略垂直)をなし、係止面38とベース部33の裏面(収容凹部35を除く部分)との間には、シャーシ22の厚さ寸法と反射シート27の厚さ寸法とを加算した寸法と同等の寸法が開けられている。
シート挿通孔40Aの孔縁のうちの下縁は、係止脚部32Bの被押圧部36の外縁のうち挿入部32A側とは反対側の縁に沿って位置している。

次に、本発明を具体化した実施形態4に係るテレビ受信装置TVを図20~図24によって説明する。
本実施形態のテレビ受信装置TVは、反射シート27に形成されたシート挿通孔70の形状が、複数のランプクリップ30間で異なるように設定されている点で、実施形態1とは相違する。なお、実施形態1と同様の構成には同一符号を付して重複する説明を省略する。
挿通孔40のうちシャーシ22に形成されたシャーシ挿通孔40Bの幅寸法(シャーシ22の長手方向に沿う方向の幅寸法)は、係止部74の挿入部32Aおよび一対の係止脚部32B(係止爪37を除く)の対向方向の幅寸法と同等の寸法に設定されている。そして、各シャーシ挿通孔40Bの孔縁部のうちシャーシ22の長手方向に対向する両縁部に、一対の係止爪37が裏側から係止するようになっている。なお、各シャーシ挿通孔40Bのシャーシ22の長手方向に沿う方向の幅寸法は、ベース部33の短手方向の幅寸法よりも小さくされている。
本発明は上記記述及び図面によって説明した実施形態に限定されるものではなく、例えば次のような実施形態も本発明の技術的範囲に含まれる。
(8)実施形態3では、係止脚部32Bは、断面略矩形の柱状をなしているが、これに限らず、例えば図30に示すように、係止脚部130のうち少なくともシート挿通孔131の孔縁に押圧操作される被押圧部132を断面略三角形をなすものとして、係止脚部130のうち挿入部32Aとの対向面とは反対側の面を傾斜面133とし、シート挿通孔131の傾斜部134を、この被押圧部132の傾斜面133の傾斜に沿う勾配をなすものとしてもよい。これにより、係止脚部130は、シート挿通孔131の孔縁に押圧されて係止孔部131Aから係止解除孔部131B側へスムーズに移動するから、ランプクリップ30の取り外しを容易に行うことができる。
