CONSTITUTION:In a bottomed cylindrical case 10 of roughly a rectangular parallelepiped whose upper end is opened, a cylindrical inserting part 20 of aroughly a rectangular parallelepiped is combined so as to be flexible. A claw part 20a of the lower end of the inserting part 20 is fit to a fixed groove part 14 in the vicinity of the upper end of the inside of the case 10, and fixed to the case 10 in an extended state. The inserting part 20 contains a motor 25, and a toothbrush main body 30 is attached and detached to and from a rotary shaft 23 protruded from the upper end part. In the side face of the case 10, a battery 12 is contained, and a battery is changed by detaching a cover 11. By extending the case 10 and the inserting part 20, and driving the motor 25 by a switch 13, teeth are brushed.
