It acts on As a result, the suction passage 37 has the suction port 2.
Dust and air are sucked in through slit 3.
0. Air passage 26. Clean air is sucked in through the slit 28. At this time, the air sucked through the slit 30 cools the motor 25 as it flows through the air passage 26. The air sucked into the suction passage 37 in this way is transferred to the rotating pipe 25. It is sucked into the cleaner body 8 via the extension pipe 12.11 and the suction hose 9.

On the other hand, when the power of the vacuum cleaner main body 8 is turned on, the suction tool 16
The motor 25 operates, and the rotation of the rotary drive shaft 25a, which is the output shaft of the motor 25, is caused by the rotation of the pinion 34. The signal is transmitted to the rotating brush 19 via the gear 39, and the rotating brush 19 is rotationally driven. By this rotation, the rotating brush 19 stirs up dust and the like attached to the surface to be cleaned, and reliably sucks the dust into the suction passage 37 side.

Since such a suction tool 16 has a narrow width, it is convenient to use it for cleaning narrow spaces such as shelves and crosspieces.

In the embodiment described above, the motor 25 and the rotary drive shaft 25
Although the example in which a and the rotating brush 19 are arranged in series is shown,
It is not necessarily limited to this.
