- the bristle bundle 1 has a thickness of 0.1 to 0.1 to satisfy an appropriate buffering by elastic buckling against the gums and periodontal pockets while securing a brushing action and a beat action. It is preferable that bristles with a diameter of about 2 mm have a bundling shape with a diameter of approximately 1 to 3 mm in terms of a circle, and more suitable as a bunch of about 100 with bristles having a thickness of 0.13 mm. . Further, if the length of the hair foot exceeds 11 mm even at 1 mm, the waist becomes too weak and the buffering action is reduced. Therefore, it is preferable that the length is less than 11 mm. In addition, the bristle bundle 1 has an advancing / retreating distance of about 4 to 6 mm so that the beat effect is high and subtle elasticity and waist strength that does not cause excessive stimulation are obtained.
- the bristle bundle 1 employs a material of nylon or polyester. According to this, it is suitable for obtaining subtle elasticity and waist strength with high beat effect and without excessive stimulation. However, it is not limited to this.
- the bristles repeatedly abut against or enter the teeth, gums, interdental teeth, and periodontal grooves as the bristles advance and retreat.
- the bristle bundle retreats while ensuring that high-speed, exciting massage by brushing and beat action is automatically performed by isolating the rocking member and the back of the bristle bundle from the heel by the knock guard.
- the problem was that the toothbrush tip became larger and bulky due to the space saving by retreating the knock guard at the tip of the swinging member into the window, resulting in reduced workability. The problem can be avoided.
