Abstract

To achieve improvement in further quietness while suppressing reduction in air capacity.SOLUTION: A blower device (100) includes impeller (220), a motor (200) and a casing (300). The casing (300) includes: a cylinder (310) having two opening parts (301, 302) opening in an (X) axial direction; a base (320) for supporting the motor (200); a plurality of spokes (330) for connecting the cylinder (310) and the base (320). In each of the plurality of spokes (330), a side surface on the side of the one opening part (301) out of the two opening parts (301, 302), a side surface on the side of the other opening part (302), and a through-hole (330i) extending in the (X) axial direction are formed. The through-hole (330h) penetrates the side surface on the side of the one opening part (301) and the side surface on the side of the other opening part (302).SELECTED DRAWING: Figure 5
