Furthermore, since the brush 24 is housed in the outer right 40 and the outer left 41, the tip of the brush 24 protrudes from the outer right 40 and the outer left 41, so that the surface to be cleaned can be prevented from being damaged. At the same time, simple cleaning with the brush 24 is possible, and further, problems such as the brush 24 sticking to the outer right 40 and the outer left 41 and not coming out can be prevented. In addition, by setting the angle α of the brush 24 to 60 °, the tip end surface of the brush 24 is substantially parallel to the handle 12, and the handle 12 can be moved in a natural posture, so that cleaning can be performed easily.

  Next, when the brush 24 is housed or when the extension pipe 13 is connected to the pipe member 22, the elastic force of the brush 24 is set to be equal to or greater than the urging force (elastic force) of the hook spring 27. The engaged portion A39 is engaged with the engaging portion A38 of the buckle 32 by pressing the brush 24 against the surface to be cleaned, rotating the tip pipe 14 in the direction C, and rotating the brush holder 25 as shown in FIG. The brush holder 25 is held above the pipe member 22 and is easily accommodated in the outer right 40 and the outer left 41 so that the connection port 31 of the extension pipe 13 is connected to the connection port 26 of the pipe member 22. It can be easily inserted and can be connected to the extension tube 13 as shown in FIGS. In addition, since most of the brush holder 25, the cover body 45, and the brush 24 are stored in the outer right 40 and the outer left 41, it is difficult to touch the brush holder 25 and the brush 24 that are easily soiled in the storage state. It is hygienic because the dirt is not noticeable.

  In addition, by arranging a cover body 45 that covers a gap generated between the brush holder 25 and the pipe member 22 when the brush holder 25 is positioned at a certain angle α, the pipe holder 25 is not enlarged, and the pipe holder 25 is not enlarged. A communication portion 25A can be formed between the member 22 and the small suction tool 21 can be provided even if the rotation angle α of the brush holder 25 is increased to expand the cleaning range.

  Therefore, it is not necessary to attach or remove the suction tool 21 used for cleaning the sofa or the wall, and the extension pipe 13 can be attached or detached without touching the suction tool 21 or the brush 24 that sucks dust. The suction device 21 can be used and stored in conjunction with it, and the usability can be remarkably improved, and the suction device 21 can be provided with a clean, excellent storage property and excellent cleaning performance. It is something that can be done.
