Description
26Rを連結する連結手段としての連結部材を用いたものである。すなわち、保持器26の左右の鍔部26LA、26RAが、熱膨張係数の大きな材料の連結部材26Fでもって連結されている。この連結部材26Fは、軸受油路29でのオイルの流れを阻害しないように、突当部材と同様に、径方向に2組、周方向に等間隔に設けられている。そして、連結部材26Fの長さ及び熱膨張係数は、エンジンの冷機時において、左右の鍔部26LA、26RAが左内輪24L及び右内輪24Rの軸方向側面と、外輪22の軸方向側面としての左右の溝側面22AL、22ARとにそれぞれ接触せず、エンジンの暖機後に当接するように設定されている。
