Abstract
A fluid bearing apparatus having a strengthened force for supporting a rotating member, which includes a herring bone-shaped dynamic pressure generating section and a spiral dynamic pressure generating section. A portion of the herring bone-shaped dynamic pressure generating section or the spiral dynamic pressure generating section is interrupted, or the spiral dynamic pressure generating section is connected to an end of the herring bone-shaped dynamic pressure generating section in order to prevent an operational fluid for generating a fluid pressure from counterflowing due to high speed rotation of the operational fluid.
