    • PROBLEM TO BE SOLVED: To provide a polygonal toothbrush which promises removal of plaque by facilitating insertion of bristles into interdental gaps, and consequently also promises the effect of preventing periodontal disease and gingivitis or the effect of massaging gum or the like.SOLUTION: The toothbrush includes a brush material 1 attached to a rotary shaft 9 provided in a handle portion 13 by fitting a rotary shaft insert shaft thereof into the rotary shaft, and a guide plate for guiding the rotation of the rotary shaft insert shaft which is provided on the handle portion 13, in which the frictional resistance between the rotary shaft 9, the rotary shaft insert shaft, and the guide plate are variable. Otherwise, the brush material 1 is attached to the rotary shaft 9 of the handle portion 13 through a rotary shaft insert hole thereof so that the frictional resistance between the rotary shaft and the rotary shaft insert hole of the brush material is variable.
    • 要解决的问题:提供一种多边形牙刷,其通过促进将刷毛插入牙间隙而允许去除斑块,并且因此也能够预防牙周疾病和牙龈炎的效果或者按摩口香糖等的效果。 解决方案:牙刷包括刷子材料1,该刷子材料1通过将旋转轴插入轴装配到旋转轴中而附接到设置在手柄部分13中的旋转轴9和用于引导旋转轴插入件的旋转的引导板 设置在手柄部13上的轴,其中旋转轴9,旋转轴插入轴和导向板之间的摩擦阻力是可变的。 否则,刷子材料1通过其旋转轴插入孔附接到手柄部13的旋转轴9,使得旋转轴与刷子材料的旋转轴插入孔之间的摩擦阻力是可变的。 版权所有(C)2013,JPO&INPIT

    • Provided is a polygonal toothbrush that enables bristles to more easily enter spaces between teeth to remove plaque, and as a consequence, can have a preventive effect on periodontal disease and gingivitis, as well as a massaging effect on gums and the like. This toothbrush is characterized in that a rotating-shaft receiving shaft of a brush material (1) is fitted and attached to a rotating shaft (9) provided on a handle part (13), and a guide plate that guides the rotation of the rotating-shaft receiving shaft is provided on the handle part (13) such that the friction resistance between the rotating shaft (9), the rotating-shaft receiving shaft, and the guide plate can be varied; or the brush material (1) is attached, at a rotating-shaft receiving hole thereof, to the rotating shaft (9) provided on the handle part (13) such that the friction resistance between the rotating shaft and the rotating-shaft receiving hole of the brush material can be varied.
