Abstract
A centrifugal fan device includes a diverting member the height of which is lower than the height of an interior wall surface of a casing. The diverting member diverts the air flowing to an air outlet into a centrifugal fan side and a side wall side of the diverting member and also diverts the air flowing to the air outlet into a first cover side and a second cover side of the diverting member. As a result, the amount of air blown from the air outlet is dispersed uniformly over the entire area of the air outlet, and a deviation in the amount of air blown out of the air outlet is reduced.
