A fluid bearing apparatus having an increased contact area between a body and a bushing and having a compact size. In the fluid bearing apparatus according to the present invention, a body extends from a shaft fixed to a lower bearing bracket in a lengthwise direction, which has a conical groove at one end and a truncated cone at the other end. An upper bushing includes a recess for receiving the one end of the body and having a conical protrusion formed therein. The conical protrusion is inserted into the conical groove of the body. A lower bushing has a recess receiving the other end of the body and a through hole extending through the lower bushing. The shaft is slidably inserted into the through hole. The upper bushing is separately combined with the lower bushing. Accordingly, the bushing which receives the body, may be decreased in volume, so that a motor to which the fluid bearing apparatus is applied, can be reduced in a total size.
