[0002]

2. Description of the Related Art Conventionally, rotary brushes of this kind have been used in various fields, such as toothbrushes, cup wheel diamond brushes for polishing, cleaning brushes for cleaning floors and roads, and whisks. The rotation of the rotating brush was a perfect circular motion, so that the force and direction of the centrifugal force were constantly constant, and the rotating position of the brush was constantly rotating at the same position.

[0003]

For this reason, in a conventional brush, for example, it is difficult to remove food residue caught between teeth or fine dirt inside a concave portion such as a floor surface in a toothbrush. Takes time to make fine bubbles,
Further, the brush, the polished surface, the floor surface, and the like are easily damaged. In particular, attention must be paid to the corners, and in addition, seizure due to frictional heat often occurs.

A rotational rotation converting means for converting the rotational rotational movement, an output rotary shaft which is converted by the rotational rotational conversion means to perform a rotational rotational movement, and a brush attached to the output rotational shaft; This causes the brush portion to swing and rotate.

Accordingly, it is an object of the present invention to reduce the impact on the teeth, the polished surface, the floor surface, etc., to reliably remove dirt and the like, and to reduce fine bubbles by making the oscillating rotational motion a rotating brush. Create a rotating brush that can be set up in time,
It is intended to provide this.

[0006]

According to the present invention, the rotary brush having the oscillating rotation is provided with the oscillating rotation converting means, so that the circular rotation of the driving source is converted into the oscillating rotation and transmitted to the rotating brush. In addition, while the rotating brush is oscillating and rotating, it cleans teeth, grinds a polished surface, cleans a floor and a road, and lathers.
