Even if a force is applied to the brush holder 22 in the direction of rotation, the stopper A and the locked portion A36 are not easily damaged, and the strength and durability are excellent without damaging the strength of the stopper A and the locked portion A36. The suction tool 18 can be provided.

  Further, it goes without saying that the same effect can be obtained even when the suction tool 18 is fixed to the distal end portion of the distal end pipe 14 or the extension tube 13 as shown in FIG.

  In the present embodiment, the suction tool with a brush has been described. However, if the brush holder 22 can be held by the buckle A29, the connected portion A28 of the extension tube 13 is connected to the brush 21 portion. Even if the communicating portion 22A that can be inserted is not formed, for example, a similar effect can be obtained in a gap nozzle configuration in which the suction port tip is narrowed, and the stopper A26 formed on the brush holder 22 is applied to the connected portion A28 of the extension pipe 13. Needless to say, the same effect can be obtained without contact, and a simpler configuration is possible.

  In addition, since the distal end pipe 14, the pipe member 19, the extension pipe 13, and the floor suction tool 15 have the same shape connecting portion and connected portion, the extension pipe 13 can be attached in the same manner as the attachment to the distal end pipe 14. It goes without saying that the same effect can be obtained even if the suction tool 18 of the present invention is arranged at the tip.

  The configuration of the present invention is not limited to the present embodiment.

  As described above, the suction tool according to the present invention can be easily attached / detached to / from the end pipe without touching the suction tool, and can be easily performed in the operation of attaching / detaching the extension pipe and the cleaning operation. Can be stored, and it is very effective because it is hygienic and improves usability and cleaning performance.
