Fluid bearing apparatus

摘要

A fluid bearing apparatus wherein a clearance between a surface of a thrust bearing (50) supporting thrust load and a periphery of a rotary shaft (30) can be adjusted by making the thrust bearing (50) movable with respect to an end portion of the rotary shaft, preferably by means of a thrust bearing support (55) having a threaded through hole (45) for receiving a corresponding threaded thrust bearing (50). This results in an enhanced efficiency and a stable rotation of the rotary shaft at a high velocity. <IMAGE>
