PROBLEM TO BE SOLVED: To provide an interdental cleaner capable of suppressing breakage of a boundary between a shaft part and a connection part or a portion in the vicinity thereof.SOLUTION: An interdental cleaner (2) comprises a base part (10), a shaft part (60), and a cleaning part (70). The base part (10) has a grip part (20) and a connection part (30) connecting the grip part (20) and the shaft part (60). The connection part (30) has a support part (32) including a distal end part of the base (10) and supporting the shaft part (60), and a deformation part (34) interposed between the support part (32) and the grip part (20) and elastically deformable so as to allow the support part (32) to deform in a width direction with respect to the grip part (20). The rigidity of the deformation part (34) is smaller than the rigidity of the support part (32).SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】軸部と連結部との境界ないしその近傍の部位の破損を抑制可能な歯間清掃具を提供すること。【解決手段】歯間清掃具(2)であって、基部(10)と、軸部(60)と、清掃部(70)と、を備え、基部(10)は、把持部(20)と、把持部(20)と軸部(60)とを連結する連結部(30)と、を有し、連結部(30)は、基部(10)の先端部を含み軸部(60)を支持する支持部(32)と、支持部(32)と把持部(20)との間に介在するとともに、支持部(32)が把持部(20)に対して幅方向に変位するのを許容するように弾性変形可能な変形部(34)と、を有し、変形部(34)の剛性は、支持部(32)の剛性よりも小さいこと。【選択図】図2
