Abstract
Description
そして、上記クリップでは、ピン部が第2挿入位置にあるときには、第1係合爪と第2被係合部とが係合するため、ピン部の挿入方向と反対側への移動が制限される。すなわち、ピン部が第2挿入位置にあるときには、第1係合爪と第2被係合部との係合により、ピン部が筒状部内に保持される。
また、保持部材にクリップの雄部材が複数設けられているため、保持部材の一回の押し込み作業で、複数のクリップを車体に同時に取り付けることができる。すなわち、上記クリップ取付構造では、車体にクリップを取り付けるための押し込み作業の工数を低減することができる。
次に、本開示の一実施形態に係るクリップ及びクリップ取付構造を図1~図14を用いて説明する。
