Abstract: A blower device includes an impeller that is rotatable around a rotary shaft extending in an up-down direction; a motor that rotationally drives the impeller; a motor housing accommodating the motor; a cylindrical member disposed outwardly of the housing in a radial direction; and an impeller case accommodating the impeller. A gap is formed between the housing and the cylindrical member. Stationary blades are provided on one of the outer side surface of the housing and the inner side surface of the cylindrical member, and protrude towards the other side surface. At an outer portion of the housing in the radial direction, the blades are disposed side by side in a circumferential direction, and form air-current paths. At least one of the blades includes a protrusion that protrudes from a surface of the at least one of the blades facing the radial direction and contacts the other side surface.

Abstract: A motor includes a metal base plate and a resin holder extending upward from the base plate. The base plate includes a flat plate portion, a through hole passing through the flat plate portion, and a plurality of claw portions extending upward from an edge of the flat plate portion which includes the through hole. A portion of the holder is in the through hole. The holder covers a portion of each claw portion. The holder is thus engaged with each claw portion to prevent the holder from turning around a rotation axis and from coming off in an upward direction. The holder includes a gate mark near a lower surface of the flat plate portion and at a circumferential position between adjacent ones of the claw portions to make it easier for the resin to fill a cavity inside molds during a molding process.
