PROBLEM TO BE SOLVED: To provide an interdental cleaning device that can enhance insertability of floss between molar teeth interdentally.SOLUTION: The interdental cleaning device (1) has floss and a body (3) that holds the floss. The body (3) includes a handle part (10) and an arm part (60) having a pair of supports (62). The arm part (60) is provided with a curved shape so as to be projecting toward one side in the height direction. The handle part (10) is provided with a grip section (20) to be gripped with fingers and a connection section (30), where the size of the grip section (20) in the height direction is larger than the size of the connection section (30) in the height direction. The arm part (60) has a back slope (64) that inclines gradually toward one side in the height direction as it recedes from the connection section (30).SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】奥歯同士の歯間へのフロスの挿入性を高めることが可能な歯間清掃具を提供すること。【解決手段】歯間清掃具(1)であって、フロスと、フロスを保持する本体(3)と、を備え、本体(3)は、ハンドル部(10)と、一対の支持部(62)を有するアーム部(60)と、を有し、アーム部(60)は、高さ方向の一方側に向かって凸となるように湾曲する形状を有し、ハンドル部(10)は、指で挟持される被挟持部(20)と、連結部(30)と、を有し、高さ方向における被挟持部(20)の寸法は、高さ方向における連結部(30)の寸法よりも大きく、アーム部(60)は、連結部(30)から離間するにしたがって次第に高さ方向の一方側に向かうように傾斜する背側傾斜部(64)を有すること。【選択図】図1
