Abstract

　加工が簡単であり、製造コストを低減させることができる軸受構造を提供する。 　断面略半円形状の凹部を有する第１ハウジング部１３と、この第１ハウジング部１３の凹部１３ａとで断面略円形の支持孔１６を形成する、断面略半円形状の凹部を有する第２ハウジング部１４とからなるハウジングと、このハウジングの支持孔１６内に密接して配設される二つ一組の二つ割り外輪３ａ、３ｂと、両二つ割り外輪３ａ、３ｂの各内側面を転動し得るように配設される複数個の転動体４と、各転動体４を円周方向略等間隔に配置するように保持する二つ一組の二つ割り保持器５ａ、５ｂとからなり、シャフト１２が内嵌される二つ割り転がり軸受２とを備えた軸受構造１。前記支持孔１６の、ハウジング部合わせ面方向の内径を、当該合わせ面方向から９０°ずらした方向の内径よりも大きくした。
