Abstract
In the dynamic bearing device, a chamfer having a larger percentage of surface openings is continuous to the outer diameter side of a lower end surface of a bearing member, which constitutes a thrust bearing gap of a first thrust bearing part. A lubricating oil in pores of the bearing member is supplied to a gap portion through the surface openings of the chamfer, so that the gap portion can be kept at a positive pressure without becoming a negative pressure.
