Then, the fixture comes into contact with the outer circumference of the annular portion of the air guide to move the air guide in a radially adjustable manner. Since three or more fixtures are arranged on the outer circumference of the annular plate, the air guide is centered. Therefore, the air gap with the outer circumference of the axial flow fan is adjusted to be uniform over the entire circumference.
