ABSTRACT:
A dynamic pressure type fluid bearing device in which a housing and a shaft rotatable relative to each other are opposed to each other to provide inner and outer bearing surfaces for radial load. One of these bearing surfaces is formed with a groove for generating dynamic pressure and the housing and the shaft are opposed to each other in a first and a second bearing surface for thrust load. A circulation path for circulating lubricant is formed in at least one of the housing and the shaft and opens in the first and/or second bearing surface.
