PROBLEM TO BE SOLVED: To bring about longitudinal reciprocating traveling of only floss 52 bridging tips of support bodies 50 having supports facing each other in a bifurcated shape.SOLUTION: Surplus ends 52a and 52b of floss 52 bridging tips of supports of support bodies facing each other in a bifurcated shape are guided toward rotary oscillating wheels 42 and 44 that are arranged in an interdental cleaning holder body 10, and held by being wound around the rotary oscillating wheels, respectively. An oscillation mechanism of the rotary oscillating wheel, which synchronously performs the winding and unwinding of the wound surplus ends 52a and 52b of the floss, is provided to bring about longitudinal reciprocating traveling of only the floss.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】二股状に対向させた支柱を有する支柱体50の先端に架橋したフロス52のみを長手方向に往復走行させる。【解決手段】歯間清掃ホルダー本体10に配設した回転揺動輪42、44に向かって、二股状に対向する支柱体の支柱先端に架橋したフロス52余端52a、52bを導き、それぞれを回転揺動輪に巻付け保持するとともに、巻付けたフロス余端52a、52bの巻取りと繰出を同期して行う回転揺動輪の揺動機構とを備えることでフロスのみを長手方向に往復走行させる。【選択図】図1
