係合突起５を突設した構造となっている。
この樹脂製部材を樹脂製の取付基板に取付けるには第７
図に示すように、樹脂製の取付基板６の取付けるべき位

このため、取付基板６の裏面が外観量として用いられる
場合には、この“裏つツリ現客”のために外観性を著し

く上記手段による作用〉 このようにフランジ部の肉厚を外周方向に向って漸減し
たため、フランジ部と取付基板の相互間の線膨張係数に
相違があっても、フランジ部の肉厚が外周側はど源いた
め、硬化収縮時にフランジ部の外周側が取付基板に変形
追従して、湾曲やシワを生じることが少なくなる。
く本発明の実施例〉（第１〜４図） 以下、図面に基づいて本発明の詳細な説明する。
第１．２図はそれぞれ本発明による樹脂製回転溶着部材
（スタッド又は留め具）の実施例を示している。
第１図は合成樹脂で一体成形されたスタッドで、円筒状

ンジ部１１は外周方向に向って肉厚が漸減している。
第２図は柱部１０に係合用の弾性突起１４．１４を備え
た留め具で、他の部分の構造は第１図と同一である。

される。
この冷却硬化において、フランジ部１１と取付基板１７
の相互間の線膨張係数に相違があっても、フランジ部１
１の肉厚が外周側はど簿いため、フランジ部１１の方が
変形しやすくなり、硬化収縮時に取付基板１７の変形に
追従するから、取付基板１７の裏面に湾曲やシワを生じ
