Abstract
Description
上記実施形態における緩み止め部材70は、円弧状の曲面部71と、曲面部71と連続した曲面状のテーパ部73と、を有する。これに限らず、緩み止め部材70は、円弧状の曲面部71を有さず、代わりに平面状の平面部171を有し、テーパ部73が平面部171と連続した平面状に形成されてもよい。この場合は、図7に示すように、緩み止め部材70の平面部171がリングナット60の雌ねじ部に食い込み、雌ねじ部と周方向に係合すればよい。切欠き18は、雄ねじ部17の径方向に沿った断面において三角形状に形成される。そして、切欠き18の内周面と緩み止め部材70の平面部171とが接触するように切欠き18に圧入され、緩み止め部材70の平面部171の角部の一つがリングナット60の雌ねじ部に食い込み、リングナット60の雌ねじ部と周方向に係合する。
