The present invention I provide a interdental brush with the captive effect. A interdental brushes with the captive effect, side wall molding the multiple localization District 311 on the brush wire of interdental brush, each localization District 311 of the bottom wall 312, is located in the bottom wall 312 sides 313, and comprises a bottom wall 312, accommodates installation space 314 surrounded by the side wall 313, at the same time, the bottom wall 312 is installed in the housing installation space 314 of the localization Ward 311 adjacent to each other, placed to face in different directions whereby the contact direction and between the handle 33 and the housing installation space 314 for each adjacent different, this time, if it is possible to make a change in the outer edge width and brush wire outside diameter of the bottom wall 312 in a timely manner, and brush wire has can be further enhanced dual engagement fixed localization ability of the hand 33 receives the brush wire external force to fall off, or it is possible to avoid occurrence of a situation such as a rotating, it is possible to improve the safety of use . .BACKGROUND【課題】脱落防止効果を備えた歯間ブラシを提供する。【解決手段】脱落防止効果を備えた歯間ブラシは、歯間ブラシのブラシワイヤー上に複数の定位区311を成型し、各定位区311は底壁312、底壁312側辺に位置する側壁313、及び底壁312、側壁313に取り囲まれる収容設置空間314を備え、同時に、相互に隣接する各定位区311の収容設置空間314中に設置する底壁312は、異なる方向を向いて設置し、これにより各隣接する収容設置空間314と持ち手33間との接触方向は異なり、この時、底壁312の外縁幅とブラシワイヤー外径上の変化を適時に加えることができれば、ブラシワイヤーと持ち手33との二重係合固定定位能力をさらに強化でき、ブラシワイヤーが外力作用を受け、脱落し、或いは回転する等の状況の発生を回避でき、使用の安全性を向上させることができる。【選択図】図3
