PROBLEM TO BE SOLVED: To provide a center bearing support which can prevent the come-off of an inner ring from support rubber even if a rotating shaft is inclined, or rotation accompanied by an axial load is applied to the rotating shaft.SOLUTION: A center bearing support 10 comprises: substantially-annular support rubber 11; a substantially-cylindrical inner ring 20 which is pressure-inserted and fixed to an internal peripheral face of the support rubber 11; and a rolling bearing 30 which is internally fit to an internal peripheral face of the inner ring 20. A rust prevention film 26 is formed at an external peripheral face of the inner ring 20, an average film thickness of the film 26 is set to 4 to 10 μm, and the surface roughness (Rz) of the film 26 is set to 5 to 40 μm.

    【課題】回転軸が傾く又は回転軸に軸方向の荷重が伴った回転が加わったとしても、内環がサポートラバーから抜け出てしまうのを防止することができるセンターベアリングサポートを提供する。【解決手段】センターベアリングサポート10は、略円環状のサポートラバー11と、サポートラバー11の内周面に圧入固定される略円筒状の内環20と、内環20の内周面に内嵌される転がり軸受30と、を備え、内環20の外周面にサビ防止用の被膜26が形成され、被膜26の平均膜厚が4〜10μmに設定され、被膜26の表面粗さ(Rz)が5〜40μmに設定される。【選択図】図1
