Abstract
This blower apparatus includes an air blowing portion including a plurality of flat plates; a motor portion; and a housing. The housing includes an air inlet and an air outlet. At least one of the flat plates includes an inner annular portion, an outer annular portion arranged radially outside of the inner annular portion, ribs each of which is arranged to join the inner and outer annular portions to each other, and air holes each of which is surrounded by the inner and outer annular portions and circumferentially adjacent ones of the ribs. With the inner annular portion and the outer annular portion being joined to each other through the ribs, an increase in the opening area of each air hole, which is defined between the inner and outer annular portions, can be achieved. This leads to improved air intake efficiency, resulting in improved air blowing efficiency.
