この樹脂製部材を樹脂製の取付基板に取付ける

このため、取付基板６の裏面が外観品として用
いられる場合には、この“裏ウツリ現象”のため
に外観性を著しく低下させてた。
＜本発明の目的＞ 本発明は、このような外観性の低下を招く“裏
ウツリ現象”の発生をできる限り少なくするため
にフランジ部の形状を改造して過剰熱による影響
を低減した樹脂製回転溶着部材を提供することを
目的としている。
＜本発明の手段＞ 上記目的を達成するため、本発明では、樹脂製
回転溶着部材のフランジ部の取付面と反対面に中

したことを特徴としている。
＜上記手段による作用＞ このようにフランジ部の取付面の反対面に中央

激しく巻き込まれて、摩擦熱の発生量が減少し、
回転溶着時に空気を巻き込むため過剰熱が奪われ

の膨出が少なくなる。
＜本発明の実施例＞（第１〜８図） 以下、図面に基づいて本発明の実施例を説明す

第４図の如く、留め具の弾性突起１４，１４の下

なお、リブ１３は第５，６図の如く傾斜させて
