ABSTRACT:
A hydrodynamic bearing apparatus comprises at least two hydrodynamic bearing units which rotatably support a rotation member against a fixed member by hydrodynamic pressure of a lubricant filled in a bearing space. A thrust plate is adhesively bonded on one of the rotation member and fixed member to support the rotation member in an axial direction. The thrust plate and rotation member or fixed member form a junction. A mechanical bonding device bonds the thrust plate onto one of the rotation member and fixed member. A sealing agent prevents the lubricant from leaking from the junction between the thrust plate and the rotation member or fixed member. The sealing agent fills a space that communicates with the junction.
