Description
前記スペーサにおけるベアリング側の端面に比べて、前記スペーサにおけるロータ側の端面の広さが広く、前記スペーサの外周面に前記ベアリング側に近づくに従って縮径するテーパー面を有し、
前記スペーサにおけるロータ側の端面に形成された凹み部内に当該スペーサのバランスを修正するためのバランス修正部が配置され、前記スペーサにおけるロータ側の端面の前記凹み部より当該スペーサの中心軸に対して外方の領域が前記ロータとの接触面とされている。
このような構成により、スペーサのバランスを修正しつつ、スペーサにおけるロータ側の端面の凹み部より当該スペーサの中心軸に対して外方の領域をロータと良好に接触させることができる。よって、スペーサの中心軸に対する当該スペーサの重心位置のズレが少なく、且つロータと良好に固定することが可能である。
