ABSTRACT:
A fluid bearing apparatus in which dynamic pressure generating grooves are subjected to a change in shape to increase the amount of fluid to be introduced into the grooves of a thrust bearing. In the fluid bearing apparatus, in order to introduce an increased amount of fluid into the dynamic pressure generating grooves formed on a side of the thrust bearing which supports a rotating shaft, a fluid inlet of the dynamic pressure generating grooves is shaped with arc portions for the fluid to be easily introduced thereinto. Accordingly, a fluid pressure in the dynamic pressure generating grooves is increased.
