Abstract:
A toothbrush configured so that a shock-absorbing section for preventing the bristles from bending is prevented from peeling away.
A toothbrush (1) wherein a head section (2) in which the bristles are implanted is configured in such a manner that the surfaces between a bristle implanting surface (5) in which the bristles are implanted and side surfaces (6) which are adjacent to the bristle implanting surface (5) are rounded surfaces (7), that bristle implanting holes (4) are formed in the bristle implanting surface (5), and that the peripheral edges (42) of the bristle implanting holes (4) are formed as a shock-absorbing section (30) which consists of a resin having a lower hardness than the material of a base (20). The shock-absorbing section (30) is joined in the regions of the rounded surfaces (7) to the base (20). The joint surfaces (22) between the shock-absorbing surface (30) and the base (20) are sloped surfaces which slope to the outer sides of the head section (2) relative to the bristle implanting surface (5).
