Abstract
A blower duct includes a path section including an entrance path section having an inlet through which air is taken in, a first bent path section, and a second bent path section having an outlet facing a longitudinal-direction portion; a first flow control member that makes a portion of the path of the first bent path section narrower than other portion of the path and causes an elongated gap extending in the longitudinal direction to pass the air; and a second flow control member constituted of an air permeable member having air permeable sections at the outlet. One of the paths located downstream of the first flow control member in an air flowing direction is partially provided with an inclined inner wall surface that is inclined from above to extend toward an upper portion of a downstream opening end of the narrowed path in the first flow control member.
