Abstract
An oil dynamic bearing, a motor and a disk drive adapted to be reduced in both size and thickness are disclosed. The oil dynamic bearing (B) includes at least two bearing portions (B, B), each having a bearing near end nearer to the rotational axis or the bearing center of the bearing and a bearing far end farther from the rotational axis or the bearing center of the bearing. The near and bearing far ends are each connected to a taper seal portion, which in turn communicates with the atmosphere. The taper seal portion connected to the bearing near end of the bearing portion (B) and the taper seal portion connected to the bearing near end of the other bearing portion (B) make up a common taper seal portion.
