るものである。As a place where tooth decay is likely to occur, especially the adjacent surface (between the teeth 18 and 17) 17
(See FIG. 8). Currently adjacent surface 17
The so-called "push-and-shake polishing" is becoming the main method of brushing. That is, as shown in FIG. 8, first, the brush portion 16 of the toothbrush is applied to the tooth row, and the bristle tips of the nylon bristles 15 are inserted into the adjacent surface 17. When the bristle tips of the nylon bristles 15 are inserted into the adjacent surface 17, the brush portions 16 are swung laterally so that the bristle tips of the nylon bristles 15 do not come off from the adjacent surface 17 (arrow a,
B). Then, the tips of any nylon bristles 15 have an adjacent surface 1
Moves as if it moves into or out of position 7 while flexing. When the brush part 16 is shaken about 20 to 30 times at one place, the plaque on the adjacent surface 17 drops due to the action of the tips of the nylon bristles 15. By the way, in the above-mentioned conventional toothbrush, since the nylon bristles 15 are directly and vertically planted on the flat surface of the end of the handle portion 14, in order to insert the bristle tips of the nylon bristles 15 into the adjacent surface 17, The brush part 16 must be pressed firmly against the dentition. However, if the brush portion 16 is strongly pressed against the tooth row in this manner, the gingiva may be damaged by the tips of the nylon bristles 15, and the portion may become purulent. The present invention has been made in view of such a current situation, and provides a toothbrush that can easily insert the tips of nylon bristles into the adjacent surface without pressing the brush portion strongly against the tooth row. It is intended.

A plurality of cylindrical recesses 4 are formed at regular intervals on the base 3 of the handle 3 at right angles to the long axis direction of the handle 1. Inside the recesses 4, cylindrical rotating bodies 5 are formed. It is housed. Here, on the peripheral surface of the rotating body 5, the ridges 5 are formed along the axial direction thereof.
a is formed, and the ridge portion 5 a is positioned at the opening of the recess 4. Further, contact surfaces 4a, 4a are formed on both sides of the opening of the recess 4 so that the protrusion 5a is brought into contact with the contact surfaces 4a, 4a. As a result, the rotating body 5 can rotate only within a certain range in the major axis direction of the handle 1. Nylon bristles 6 are vertically planted at both ends of the upper surface of the ridge 5a. By configuring the brush portion 2 as described above, the nylon bristles 6 and 6 planted in the adjacent rotating bodies 5 and 5 are tilted by the rotation of the rotating bodies 5 and 5 so that their bristle tips come into contact with each other. Can be made (dotted line in FIG. 3).

When the brush portion 2 of the toothbrush A is applied to the dentition, the tips of the nylon bristles 6 try to slide on the surfaces of the teeth 18 (FIG. 8), whereby a rotational force acts on the rotating body 5 via the nylon bristles 6. To do. This rotation of the rotating body 5 causes the nylon bristles 6 to tilt (indicated by the one-dot chain line in FIG. 3), and the tips of the nylon bristles 6 smoothly enter the adjacent surface 17 (between the teeth 18 and 18) ( (State of FIG. 8). In this way, the tips of the nylon bristles 6 can be attached to the adjacent surface 17 by simply applying the brush portion 2 to the dentition.
Since it can be made to enter, the tip of the nylon hair 6 does not damage the gums, and as a result,
There is no risk of gingival suppuration. When the bristle tips of the nylon bristles 6 are inserted into the adjacent surface 17 as described above, the brush portion 2 is swung laterally so that the bristle tips of the nylon bristles 6 do not come off from the adjacent surface 17. Then, the tips of any nylon bristles 6 move in such a manner that the tips of the nylon bristles 6 move into the adjacent surface 17 while moving or not moving. Nylon bristles 6 when the brush part 2 is shaken about 20 to 30 times at one place.
The plaque on the adjacent surface 17 drops due to the work of the hair tips.

ッシング効果が向上する。In the above embodiment, the nylon bristles have the handle 1.
Although it is configured to incline only in the major axis direction, the following effect can further enhance the effect. That is, as shown in FIGS. 4 to 6, a plurality of spherical recesses 10 are formed on the upper surface of the pedestal 9 of the brush portion 8 at equal intervals, and each of the recesses 10 has a spherical shape. The rotating body 11 is housed. Here, the rotating body 1
A ridge 11a is formed on the outer surface of No. 1 in the radial direction, and the ridge 11a is positioned at the opening of the recess 10. Further, a contact surface 10a is formed along the inner circumference of the opening of the recess 10 so that the ridge 11a is brought into contact with the contact surface 10a. Thus, the rotating body 11 can freely rotate only within a certain range. The ridge 1
Nylon bristles 12 are planted in 1a. By configuring the brush portion 8 as described above, each nylon bristles 1
2 can tilt freely within a certain range (Fig. 5,
As a result, since the tips of four adjacent nylon hairs 12 can be gathered together, the number of nylon hairs 12 entering each adjacent surface 17 increases and the brushing effect is improved.
