Abstract: A blower duct includes a path section and multiple suppressing sections. The path section connects an inlet and an outlet and allows air to flow therethrough. The suppressing sections are provided at different locations in the air flowing direction and suppress the flow of the air. The path section at least has an entrance path section and a first bent path section. One of the suppressing sections is a first suppressing section including a blocking portion and openings. The blocking portion is disposed in the first bent path section and blocks the flow of the air. The openings are disposed at different positions in one direction and include a first opening disposed closest to the inlet at a first height position where a height from a reference base surface of the first bent path section is larger than the remaining opening or openings.
