WIPO Patent Application WO/2020/262341
Kind Code:
The purpose of the present invention is to provide a toothbrush that is gentle on the teeth and gums and that gives useability with a pleasant sensation, while easily preventing overbrushing. This toothbrush comprises: a head part (10) that is provided at a distal end in a longitudinal direction and that has a bristle surface (11); a gripping part (30) disposed further toward a rear end than the head part; a neck part (20) disposed between the bristle surface and the gripping part; and a deformation part (70) that includes a hard section (70H), which is disposed further toward the rear end than the bristle surface and which is formed from a hard resin, and a soft section (70E), which is formed from a soft resin and which coats at least a portion of the hard section. The deformation part is deformed by an external force in a first direction which orthogonally intersects the bristle surface and is compressed as a result of the hard section sandwiching the soft section in the longitudinal direction.
