<P>PROBLEM TO BE SOLVED: To provide a blower capable of preventing entry of dust into the inside of a rotor where a motor is housed, to allow the dust to be discharged from the inside of the rotor, and to efficiently prevent motor lock as compared with conventional ones. <P>SOLUTION: An opening 21 of a rotor 20 where a motor 35 is housed and a circuit board 40 are covered with a cover 50A, and the entry of dust into the rotor 20 is prevented by the cover 50A. An air current is generated by a fin (air current generation means) 54 formed at the cover 50A rotated integrally with the rotor 20 to prevent the entry of dust into the rotor 20, and the dust in the rotor 20 is discharged to the outside of the rotor 20. <P>COPYRIGHT: (C)2013,JPO&INPIT |
