Abstract
【解決手段】蓋部材10の外周面をブラケットの内周面10b2に固定し、両者の固定力を高める。蓋部材に、プレート部10aと、外側部材Aの内周面10b2又は外周面10b1に固定される固定面Bとを設け、この固定面をプレート部の肉厚よりも大きい軸方向寸法にすれば、プレート部を薄肉化すると共に、固定面と外側部材の内周面との間の固定力を向上させることができる。

Claims (5)
- ブラケットの内周面に固定され、軸方向両端を開口した外側部材と、外側部材の内側に挿入された軸部材と、外側部材の一端開口部を密閉する蓋部材と、軸部材の外周面に面し、一端が蓋部材で密閉された空間につながるラジアル軸受隙間とを備え、ラジアル軸受隙間に形成した油膜で軸部材を回転可能に支持する流体軸受装置において、
蓋部材をブラケットに固定したことを特徴とする流体軸受装置。 - さらに、蓋部材を外側部材に固定した請求項1記載の流体軸受装置。
- 蓋部材に、プレート部と、外側部材の外周面に固定される固定面とを設け、固定面の軸方向寸法をプレート部の肉厚より大きくした請求項2記載の流体軸受装置。
- 蓋部材が、プレート部の外径端から軸方向に延びた固定部を備え、その固定部の内周面に前記固定面を有する請求項3記載の流体軸受装置。
- 蓋部材の固定面を外側部材の外周面に固定すると共に、蓋部材と外側部材との間に形成され、かつ外側部材の外周に開口した開口空間を、外側部材の外周面にブラケットを接着固定する際の接着剤溜りとした請求項3記載の流体軸受装置。
