<P>PROBLEM TO BE SOLVED: To provide a vacuum cleaner which can reduce the rotation vibration and noise of a motor fan. Ž<P>SOLUTION: The motor fan 31 equipped with a fan 48 and an electric motor part 32 is supported by first and second support means 11 and 21 within a cleaner body 2. The fan 48 has a larger diameter than the maximum diameter of a rotor 39, which the electric motor part 32 has, and this fan 48 is attached to one end part of a rotor axis 40. The first support means 11 supports a bearing housing part 34 on the cleaner body 2. The second support means 21 is prepared so as to divide the electric motor part 32 and the fan 48 and supports a bearing housing part 35 on the cleaner body 2. The second support means 21 has a cover mounting part 27, which has a larger diameter than the fan 48, and a ventilation part 28 through which air cooling the electric motor part 32 passes. A fan cover 51, which covers the fan 48 and holds the fan 48 between it and the second support means 21, is supported by the cover mounting part 27. A gap G is formed between the outer periphery of the fan cover 51 and the inside of the cleaner body 2. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
