This invention designates that both of the gearwheel polishing make the brush between the possible toothbrush combined use electromotive gearwheels cleaning between the gearwheels and as topic making use of one case itself. By the vibration which is output vibrating generation means (11) with, vibrating generation means (11) Drive power source (12) with, vibrating generation means (11) and Drive power source (12) the switch (14) the control section which is included (13) the case itself which is internalized (1) vibrating generation means (11) by in the Tip as the brush component between the gearwheels which the reciprocate are done (2) it is laid out the case itself (1) according to axis, the toothbrush (311) you attach to the Tip and the toothbrush component which opens the base which facilities is done (3) is overturned and the brush component between the gearwheels removes (2) possibly the case itself (1)It was the Inlaying equipment possible in the Tip, the Inlaying equipment when pointing the toothbrush component (3), the toothbrush (311) the reciprocate is done with the vibration which is output vibrating generation means (11) by.本発明は、1つのケース本体を用いて歯間の清掃および歯磨きの両方が可能な歯ブラシ兼用電動歯間ブラシとすることを課題とする。振動発生手段(11)と、振動発生手段(11)の駆動電源(12)と、振動発生手段(11)および駆動電源(12)のスイッチ(14)を含む制御部(13)を内蔵したケース本体(1)の先端に振動発生手段(11)により出力される振動により往復動する歯間ブラシ部材(2)がケース本体(1)の軸線に沿って配置されているとともに、先端に歯ブラシ(311)を付設した底面を開放した歯ブラシ部材(3)が歯間ブラシ部材(2)を覆って取り外し可能にケース本体(1)の先端に嵌装可能であり、歯ブラシ部材(3)を嵌装させたときに振動発生手段(11)により出力される振動により歯ブラシ(311)が往復動するものとした。
