Therefore, a rotary force of the driving motor 50 is transferred to the brush 52 by an attractive force working between the magnetic body and the magnet. If a load is generated, for example, as the brush 52 is caught by a stuff, a magnetism of the magnet is overcome, and only the magnetic body is rotated, thereby preventing transfer of the load generated at the brush to the driving motor 50 .

  • the driving force transfer device 58 will now be described. First, as shown in FIG. 7 , when the driving motor 50 is driven, the first magnet 60 mounted at the rotary shaft 54 of the driving motor 50 is rotated, and the second magnet 62 positioned to face the first magnet 60 is rotated by an attractive force working between itself and the first magnet 60 , thereby rotating the second brush 52 connected to the second magnet 62 .
  • the driving motor 50 is continuously and normally rotated because the rotary force of the driving motor 50 is greater than the attractive force working between the first magnet 60 and the second magnet 62 . Accordingly, the driving motor damage due to an overload can be prevented.
  • the first magnet and the second magnet are disposed between the driving motor and the brush in a facing manner, and a rotary force of the driving motor is transferred to the brush by an attractive force working between the first magnet and the second magnet, so that the driving motor is normally rotated even if rotation of the brush is stopped as the brush is caught by a stuff or the like. Accordingly, the driving motor can be prevented from being damaged by an overload.
  • the brush is driven only by a force corresponding to an attractive force working between the first magnet and the second magnet, if friction severely occurs between the brush and the floor, the brush stops rotating, thereby preventing floor damage.
