ABSTRACT:
A hydrodynamic bearing device in which an introducing minimum clearance for causing capillary phenomenon is formed from the location in the proximity of the opening of a communicating path to the open end of the bearing hole in between the cover and the end face on the open end of the sleeve so that the operating fluid from the communicating path in the sleeve flows into the bearing hole by the capillary phenomenon; a vent hole leading to the outside air is formed on the cover; a fluid storage space for storing the operating fluid is formed on the inside surface of the cover or the end face on the open end of the sleeve to communicate the introducing minimum clearance and the vent hole in the circumferential direction; and the air bubbles separated at the fluid storage space are exhausted outward from the vent hole.
