    摘要： A vacuum cleaner comprising: a fan motor (6) disposed in a main body case (1) thereof and having a motor (10) arranged in such a manner that its rotor (13) or its stator (14) uses a permanent magnet (12) and a fan arranged to be rotated by the motor; a dust-­collecting chamber (1a) for collecting dust sucked into the main body case due to the rotation of the fan motor; and a dust-collecting filter (5) for causing the dust sucked into the main body case to be caught in the dust-­collecting chamber, wherein magnetic material adhesion preventing device (20) (21) (22) (25) (26) (27) (29) (30) is provided in a passage through which air flows due to rotation of the fan motor, the magnetic material adhesion preventing device acting to prevent adhesion of fine dust composed of magnetic materials included in the air flow to a portion in the vicinity of the permanent magnet. As a result, the sticking taken place between the rotor and the stator due to adhesion of fine dust between them can be prevented, causing the life to be elongated and the reliability to be improved.
