<p>PROBLEM TO BE SOLVED: To provide an electric toothbrush holder wherein a frictional resistance which arises when a toothbrush receptor reciprocates can be reduced, and which can be miniaturized. SOLUTION: In a main body 2, a battery 3, a motor 4 which makes the battery 3 a driving source, a driving mechansim 8 which is driven by the motor 4, and a toothbrush receptor 6 which reciprocates in the verticval direction by the driving of a driving mechanism 5 and holds a toothbrush are housed. Then, at the tip end and the base end of the toothbrush receptor 6, at least one rolling bearing is provided respectively, and the reciprocating motion of the toothbrush receptor 6 is performed through the rolling bearing.</p> |
