Abstract
A ceramic turbo charger rotor having a bearing structure in which an inner race of an angular ball bearing and a spacer are assembled to a journal shaft as one unit in such a manner that one end of the spacer is assembled to a turbine-side connecting portion of the journal shaft by a pressure inserting manner and the other end of the spacer is assembled to a compressor-side connecting portion of the journal shaft by a clearance fitting manner. Therefore, the deviation between a center axis and a rotational axis of the rotor caused by the pressure insertion of the spacer is released at the compressor side and the amount of the unbalance before correcting of the rotor is remarkably reduced.
