  • Publication number: 20220015531
    Abstract: A toothbrush enables an appropriate brushing pressure and includes a sensing portion for sensing that an external force in a first direction orthogonal to the bristle tufting surface exceeds a predetermined value on a rear end side from the bristle tufting surface. The sensing portion changes a relationship between a displacement amount of the head portion when a load is applied to the head portion and a repulsive force generated according to the displacement amount from an increase to a decrease in the repulsive force at a first threshold value. The first threshold value relates to an increase in the displacement amount, and stops the decrease in the repulsive force at a second threshold value. The second threshold value relates to when the displacement amount is larger than the first threshold value.
