Abstract
This blower apparatus includes an air blowing portion including a plurality of flat plates arranged with an axial gap defined between adjacent ones of the flat plates; a motor portion arranged to rotate the air blowing portion; and a housing arranged to house the air blowing portion and the motor portion. The flat plates include an air hole arranged to pass therethrough in an axial direction. Once the air blowing portion starts rotating, an air flow traveling radially outward is generated between the flat, plates by viscous drag of surfaces of the flat plates and a centrifugal force. Thus, gas supplied through the air inlet and the air hole travels radially outwardly of the air blowing portion. Accordingly, a reduced thickness of the blower apparatus does not result in a significant reduction in the air blowing efficiency.
