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 housing includes an air inlet and an air outlet. A rotating portion includes a hub including a flat plate holding portion arranged to hold at least one of the flat plates. 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. Since the air flow is generated between the flat plates, the air flow does not easily leak upwardly or downwardly, and thus, an improvement in air blowing efficiency is achieved.
