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. !
