PROBLEM TO BE SOLVED: To provide an interdental cleaning tool which can improve cleaning force and cleaning actual feeling while solving nocuous.SOLUTION: An interdental cleaning tool comprises: a pair of flat plate-shaped grip parts 10 which are jointed in a thickness direction and a brush part 20 which is formed on an extension axis line 40 direction where the brush part extends from the pair of grip parts by a belt-like part 30 formed of a synthetic resin and connecting the pair of grip parts. The brush part has frame-shaped parts 21, 22 which surround a surrounding of a respective center axis line orthogonal to the extension axis line by the belt-like part which is twisted around the extension axis line by elastic deformation, and which are arranged along the extension axis line. The plural frame-shaped parts are configured so that center axis lines 21a, 22a of adjacent frame-shaped parts are arranged on different positions in the extension axis line surrounding direction.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】為害性を解消しつつ清掃力及び清掃実感を向上させる歯間清掃具を提供する。【解決手段】厚さ方向に互いに接合された一対の平板状の把持部10と、合成樹脂で構成され一対の把持部をつなぐ帯状部30により、一対の把持部から延出する延出軸線40方向に形成されたブラシ部20とを備える。ブラシ部は、弾性変形により延出軸線周りに捻れた帯状部によって、それぞれが延出軸線と直交する中心軸線の周囲を取り囲み、延出軸線方向に沿って複数配列された枠状部21、22を有する。複数の枠状部は、隣り合う枠状部の中心軸線21a、22aが延出軸線周り方向について異なる位置に配置されている。【選択図】図1
