ABSTRACT:
The dynamic bearing device of the invention comprises a housing, a bearing sleeve provided inside the housing, a rotating member rotating relative to the bearing sleeve, and a dynamic bearing portion supporting the rotating member in a non-contact manner by dynamic pressure action of a lubricating fluid generated in a bearing gap between the bearing sleeve and the rotating member. The bearing sleeve has a parent body formed of a sintered metal and a bearing surface facing the bearing gap and formed by a resin layer. The dynamic pressure generating grooves are formed in the resin layer.
