PURPOSE: To improve the lifetime of a fan motor by providing a means to prevent microdusts composed of magnetic substances contained in an air flow from adhering on the permanent magnet part of the motor in the duct of the air flow generated with the rotation of the fan motor.
CONSTITUTION: The cleaner is equipped at least with a fan motor 6 composed of a motor 10 to be arranged in a main body case 1 and, moreover, to be formed by using a permanent magnet 12 for a rotor 13 or a fixing piece 14 and a fan 9 rotated by the motor 10, a dust collecting room 1a being arranged at the suction side of the motor 6 and, moreover, to collect the dust sucked into the case 1 by the rotation of the motor 6, and a dust filter 5 to capture the dust sucked into the case 1 in the dust collecting room 1a. In the duct of the air flow generated by the rotation of the motor 6, a microdust capturing filter 20 to prevent the microdust made of the magnetic substances contained in the air flow from adhering the permanent magnet part 12 of the motor 6 is provided. As a result, the lifetime and reliability of the motor 6 are improved.
