- This toothbrush is inserted into the mouth of a person and brushes while rolling, and has a configuration in which a rotating brush 5 is rotatably held on the distal end side of the handle member 1.
- the handle member 1 is formed by processing a natural bamboo material or a synthetic resin material such as plastic.
- the handle member 1 has a rear end 1a as a grip portion, and has extended pieces 2 and 3 formed on a front end 1b.
- the extending pieces 2 and 3 are forked in order to arrange the rotating brush 5, and each of them has a substantially triangular shape from the left and right sides of the recess 1f formed on the back surface 1d of the distal end 1b. Raised. Each of the extending pieces 2 and 3 has its outer surface substantially flattened starting from the extreme end 1 e of the curved handle member 1.
- the left and right extending pieces 2 and 3 are provided with recessed fitting grooves 2 b and 3 b in the inner walls of the opposing tops 2 a and 3 a, and fitted with both ends 4 a and 4 b of the support shaft 4. It is possible.
- the support shaft 4 is inserted into a shaft hole 7a formed at the center of the rotary brush 5, and both ends 4a and 4b are fitted into the fitting grooves 2b and 3b, so that the rotary brush 5 is kept rotating (see Fig. 6).
- the distance between the support shaft 4 and the recess 1 f of the handle member 1 is set such that the tip 5 b does not contact the recess 1 f while holding the rotating brush 5.
- the left and right extending pieces 2, 3 protruding bifurcated from the back surface 1d are raised in a substantially triangular shape, and each outer surface is also flat.
- the rotating brush 5 is made of a bristle brush material 6 made of synthetic resin fiber such as nylon. A large number of these are assembled to form a mouthpiece.
- a cutting tool for example, a cutting tool, a heating tool, a pressing tool, a joining tool, and the like are used in order to efficiently manufacture a large number of rotating brushes 5.
- FIG. 7 (a) a large number of bristle brush materials 6 are bundled, and as shown in FIG. 7 (a), the enameled wire E or the like is wound several times and bound to form an aggregate 7. Then, one end 7a of the assembly 7 is heated with a heating tool, and as shown in FIG. 7 (b), the bristle brush members 6 are fused so that the bristle brush members 6 do not separate from each other, and the end 7a is formed into a hemispherical shape. After this, the other end 7 b of the assembly 7 is cut to an appropriate length, and is kept.
- one end 7a of the hemisphere is pressed with a pressing tool.
- This pressing tool has parallel pressing surfaces, and when pressure is applied to the hemispherical portion sandwiched between the pressing surfaces in the direction perpendicular to the paper, it becomes a fan shape as shown in Fig. 7 (c). As the pressure increases, it becomes semicircular, as shown in Fig. 7 (d).
- FIG. 7 (f) several such circular assemblies 7 are connected to the central holes 7 d of the respective annular portions 7 c through dedicated S, and the annular portions 7 c are mutually connected. Is bonded with an adhesive.

- the rotating brush 5 is rotatably held at the distal end 1 b of the handle member 1.
- the user When using this toothbrush, the user holds the grip 1a, inserts the rotating brush 5 into the oral cavity 10, and rotates the toothbrush along the teeth 12 as shown in FIG. Then, the bristle tip of the bristle brush material 6, which is the outer peripheral portion 5b of the rotating brush 5, enters between the teeth, and the plaque and the residual plaque adhering to the peripheral surface of the tooth 12 and the back of the tooth 12 Foreign matter and the like can be removed.
- rotating the rotating brush 5 on the gums 11 massages the gums 11, which prevents or treats periodontal diseases unique to teeth 12 such as caries, as well as alveolar pyorrhea. It is effective for
- This rotary brush has the same basic configuration as that of the above-described embodiment, and differs only in the shape of the handle member.
- the handle member 9 has three small through holes 9a, 9b from the concave portion 1f where the rotating brush 5 is arranged to the upper surface 1c on the opposite side. , 9 c are drilled. As a result, the air flows through the small through holes 9a, 9b, 9c, so that the inside of the oral cavity 10 is dried and the tooth brushing can be performed without discomfort.
- the rotating brush 5 is held by supporting the support shaft 4 between the left and right extending pieces 2 and 3 provided on the handle member 1.
- a substantially L-shaped support shaft may be integrally formed, and the rotary brush 5 may be rotatably held on the support shaft.
- a stopper that is slightly larger than the shaft hole 5c of the rotating brush 5 is provided at the tip of the support shaft, and when the shaft hole 5c of the rotating brush 5 is pushed in from the stopper and held at the time of mounting, the shaft rotates on the support shaft.
- the brush 5 is held rotatably. On the other hand, when pulled strongly, it can be pulled out of the stopper, so that it can be easily attached and detached, and the rotating brush 5 can be easily replaced or cleaned.
- a toothbrush is formed by rotatably supporting a rotating brush having a large number of bristle brushes in a roller shape on a support shaft protruding from one end of a handle member.
- the rotating brush is rotated along the teeth and gums in the oral cavity while grasping the other end of the handle, the tips of the bristle brush material enter between the teeth, and the plaque and residue remaining on the teeth.
