を可能とする電気掃除機の吸込口体が知られている。2. Description of the Related Art Conventionally, there is a suction port body having a bottom surface on which a plurality of traveling wheels and a traveling roller driven by a driving means are mounted, and it is possible to move on a surface to be cleaned by a rotational force of the traveling roller. A suction port body of a vacuum cleaner is known.

ることができる。In the suction port body of this electric vacuum cleaner, the operating load can be reduced by moving it by itself through a traveling roller which is always driven during use and rotates forward or reverse. . In particular, even if the flexible tatami or carpet surface, which is the surface to be cleaned, is lifted up and sucked into the suction port opened on the bottom surface, it can be easily moved.

である。By the way, the suction port main body is provided with a clutch mechanism for transmitting or interrupting the driving force to the traveling roller according to the use condition. This is because, for example, when trying to quickly reciprocate a short distance back and forth to clean a corner of a room, etc., it is difficult to move because the traveling roller cannot keep up with the speed when it is driven, so it is difficult to move. This is because the transmission of the driving force to the roller for use is blocked and the free state is established.

At the time of cleaning, the surface to be cleaned floats up due to the suction force in the case of carpets and tatami mats, but the suction port of the electric vacuum cleaner moves on the surface to be cleaned due to the driving force of the driven rollers, and it is used for boarding etc. In the case of a hard floor, the surface to be cleaned does not rise due to the suction force, so you do not have to drive the traveling roller
Only the traveling wheels allow the suction port of the vacuum cleaner to move smoothly over the surface to be cleaned.

掃面F上の移動をスムーズに行うことができる。On the other hand, when the surface to be cleaned F is a hard floor such as a plate-covered surface, the surface to be cleaned F does not float up due to the suction force, so that the driving roller 25 is not driven and the front wheels 20 are not driven.
Also, the suction port body 10 of the electric vacuum cleaner can be smoothly moved on the surface to be cleaned F via the rear wheel 21.
【0026】同様に、例えば、部屋の隅等を掃除するた

要となり、使い勝手が良くなる。As described above, since the clutch mechanism is not required and the suction port main body is not enlarged and the weight is not increased, when assembling during use or disassembling and storing after use, it is further carried from room to room. In this case, handling becomes convenient. In addition, the clutch operation according to the use situation is unnecessary, and the usability is improved.
