- 一対の軌道輪(1、1)の対向面に設けた軌道溝(1a、1a)間に、複数のボール(2)を弾性を有する樹脂製保持器(3)に保持し、この樹脂製保持器(3)を、環状板部に前記ボール(2)を収容する複数のポケット(4)をスラスト方向に沿った縦方向の片側に引き抜く金型で形成し、これらのポケット(4)の縦断面を両端の口辺部(5a、5b)が狭まる中凹形状とするように前記金型で成形したスラスト玉軸受において、
前記樹脂製保持器(3)のポケット縦断面の中凹形状の中心を当該ポケット縦断面の中心から縦方向の前記金型を引き抜く方向と反対側へずらしたことを特徴とするスラスト玉軸受。 - 一対の軌道輪(1、1)の対向面に設けた軌道溝(1a、1a)間に、複数のボール(2)を弾性を有する樹脂製保持器(3)に保持し、この樹脂製保持器(3)を、環状板部に前記ボール(2)を収容する複数のポケット(4)をスラスト方向に沿った縦方向の片側に引き抜く金型で形成し、これらのポケット(4)の縦断面を両端の口辺部(5a、5b)が狭まる中凹形状とするように前記金型で成形したスラスト玉軸受の製造方法において、
前記樹脂製保持器(3)のポケット縦断面の中凹形状を、縦方向の前記金型を引き抜く方向と反対側の当該樹脂製保持器(3)の端面と前記軌道輪(1)とが非接触になるように前記ボール(2)の口辺部(5b)からの突出量を規定した形状に前記金型で成形し、この中凹形状の中心を前記ポケット縦断面の中心から縦方向の前記金型を引き抜く方向と反対側へずらしたことにより、前記成形した金型が引き抜かれる側の口辺部(5a)の口径が当該金型の引き抜きで拡がって当該金型を引き抜く方向と反対側の口辺部(5b)からの前記ボール(2)の突出量が前記規定した突出量から少なくなっても前記樹脂製保持器(3)の端面と前記軌道輪(1)とが接触しないようにしたことを特徴とするスラスト玉軸受の製造方法。
