摘要： A blower device includes an axial flow fan having blades to blow air, and a fan shroud that includes a cylindrical portion surrounding an outer circumference of the fan at a distance from the outer circumference, and an air guiding portion guiding air drawn by the fan. The fan shroud includes a short end part shorter in distance to the outer circumference of the fan than another part in an outer end portion of the fan shroud, and a protruding end part provided at a position advanced in a rotational direction from the short end part, protruding upstream in a flow of the drawn air more than the fan and protruding outward of the air guiding portion. Accordingly, the blower device which includes the fan shroud capable of reducing rotational noise can be provided.
