JP-A-10-118592 (see FIG. 1)

However, manual operation has a small mechanical force, and dust and dirt stuck to the cleaning surface cannot be sufficiently removed. For this reason, the cleaning surface was sometimes scratched and hardened with hard sand to try to force it off with a hard brush or spatula. Once the wrinkles are attached, the dirt becomes more difficult to peel off if it adheres again. Also, if too much force is applied with a brush or spatula, the peeled garbage will scatter around. In the case of a clearance nozzle with a brush, the brush was too soft, and it was difficult to remove dust and dirt stuck to the cleaning surface from the cleaning surface.
As described above, these series of operations are time-consuming and laborious and can be done with great difficulty. In addition, due to heavy labor, cleaning tends to be neglected, and dirt and dirt accumulate, making it difficult to remove.

  The present invention has been made to solve the above-described problem, and removes dust that has accumulated or stuck in a narrow space such as a rail groove of a sash, quickly, easily, and cleanly without scattering the dust. It is an object of the present invention to provide a vacuum cleaner suction tool and a vacuum cleaner equipped with the suction tool.
