Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a low noise compact blower applicable even under an environment with a great quantity of dust by employing the blower of a simple dust-proof structure. SOLUTION: In the blower comprising an axial flow fan 62, a motor provided with a round circuit part 70 driving the fan 62 and positioned in a hub 75 of the fan 62, and a housing 61 including a housing boss part 65 opposing to the hub 75 and fixing the motor part 66 and forming an air duct part 63 surrounding a perimeter of the fan 62 with keeping a predetermined interval, the hub 75 of the fan 62 has an inner diameter larger than outer diameter of the circuit part 70 and covers the circuit part 70, and a tip of the hub 75 is put close to the housing boss part 65. Consequently, a dust invasion entrance to a motor 66 from am opening part of the hub 75 is narrowed and complicated, a former dust-proofing structure by a dust-proofing cover is eliminated, and miniaturization/noise reduction of the blower can be achieved.
