<p><P>PROBLEM TO BE SOLVED: To provide a sufficient tooth brushing effect, to provide a brush part at low cost and to facilitate washing inside the brush part when functioning as an ion toothbrush. <P>SOLUTION: The toothbrush has a body 10 on which a hand-side electrode 15 is mounted and exposed outside, a mounting leg part 20 which has a narrow shape extending from an end of the body 10 and on which a brush-side electrode 31 is mounted on an end, and the brush part 30 removably fitted on the outer periphery of the mounting leg part 20. The brush-side electrode 31 has a projection 31a projecting laterally from the outer peripheral face of the end of the mounting leg part 20. A through-hole 81 is formed in a side face of an end of the brush part 30. When the brush part 30 is fitted to the mounting leg part 20, the projection 31a is fitted to the through-hole 81 so that the projection 31a is exposed outside. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
