このため、取付基板６の裏面が外観品として用

＜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

＜本発明の実施例＞（第１〜６図） 以下、図面に基づいて本発明の実施例を説明す

第１〜４図はそれぞれ本発明による樹脂製回転

第１，２図は合成樹脂で一体成形されたスタツ

備えている。
第３，４図は柱部１０に係合用の弾性突起１

１，２図と同一である。
なお、樹脂製回転溶着部材が配向性の高い樹脂
である場合には、回転溶着時の冷却硬化において
この配向方向（第１図、第２図で矢印Ａで示す）
に平行な方向に収納するので、溝はこの配向方向

フランジ部１１に溜まることがなく、従つて取付
基板１７の裏面側が従来の如く凸状に膨出する
“裏ウツリ現象”が生じることが少なくなる。
また、フランジ部１１と取付基板１７の相互間

なお、配向性の強い樹脂の場合には、この配向
方向に収縮するが、溝１３ａ〜１３ｄがこの配向

なお、溶着時にフランジ部１１の溝１３ａ〜１

＜本発明の効果＞ 以上説明したように本発明の樹脂製回転溶着部
