is forcibly vibrated inward, and the long groove α■ on the lever α engages with the crank pin (7), and due to this engagement, the crank pin (7) moves within the long groove α9, and the switching lever αJ and Since the brush holder (8) K is prevented from rotating in the circumferential direction of its axis, the brush holder swings from side to side, and this swing is caused by the fact that the brush holder (8) is always attached to the crank pin (7). This following action is performed by the long groove α of the crank pin (7).
(2) This is accomplished by the bending and restoring action of the elastic member (9) caused by the movement within.

As described above, according to the present invention, it is possible to automatically operate the toothbrush in the same way as actually brushing teeth by the back-and-forth movement of the brush holder and the combined movement of the back-and-forth movement and left-right rocking. In short, in the present invention, as a guide structure of the brush holder for performing the above-mentioned movement, sliding members are provided on the left and right sides of the brush holder to be engaged with the guide of the body through elastic means, and The brush holder is provided with a switching lever equipped with a long groove for engagement with a crank pin for swinging the holder. In other words, the main functional parts are collectively associated with the brush holder, thereby reducing the number of parts. This makes it possible to reduce the width to a large extent and simplify the structure, and has excellent features that cannot be expected from conventional movable toothbrushes of this type.
