2. Description of the Related Art Conventionally, a rotary polisher has been widely used as an instrument for polishing a painted surface. The rotary polisher is composed of a motor as a driving unit, a rotary shaft that is rotated by the rotation of the motor, and a rotary plate fixed to the end of the rotary shaft. A method of attaching a buff (polishing tool) for polishing a surface and rotating the buff (polishing tool) while using an abrasive to polish a painted surface has been adopted. And these buffs (polishes)
Heretofore, those made of various materials have been used. For example, urethane or other elastic material alone, urethane with disc-shaped wool affixed to the surface, urethane with multiple ring-shaped wools of different diameters affixed to the urethane surface, etc. Has been put to practical use.

[0003]

When the painted surface is polished using the rotary polisher described above, the worker holds the rotary polisher and applies a buff (polishing tool) to the painted surface. A method is used in which the parts to be polished are sequentially moved while being pressed against. However, when using such a rotary polisher, only a skilled worker can satisfactorily polish the painted surface,
Inexperienced workers cannot not only polish cleanly, but also circular polishing marks may remain on the polished surface. Therefore, as a solution to the inconvenience of using such a rotary polisher, a vibratory polisher in which a disk-shaped part (diaphragm) to which a buff (polishing tool) is fixed alternately rotates forward and backward alternately is a product. Has been According to such a vibration type polisher, no skill is required for the operator, and no circular polishing marks remain on the painted surface.

However, when using such a vibration type polisher, conventional buffs (polishing tools) often cannot be polished sufficiently, and it takes an extremely long time to complete the polishing operation. . Further, the conventional method of polishing a painted surface using a buff (polishing tool) has a poor finish and cannot be a good painted surface.

Accordingly, the present invention has been proposed to solve the problems of the above-mentioned conventional paint-surface polishing tool and paint-surface polishing method, and requires the skill of an operator. It is an object of the present invention to provide a polished tool for a painted surface and a method for polishing a painted surface in a very short time and with a good finish.
