Abstract
(EN)

PROBLEM TO BE SOLVED: To provide an electric toothbrush in which a DC motor and a vibration shaft are contained in a stem member.

SOLUTION: The electric toothbrush has a stem member, to/from which a brush part is attachable/detachable. The stem member is made of a synthetic resin, and has a hollow part for containing a DC motor and a vibration shaft connected to the DC motor. The one end of the hollow part is opened, and the DC motor and the vibration shaft are inserted therefrom, and the other end of the hollow part is closed. The free end of the vibration shaft is rotatably held in the other end of the hollow part. The hollow part has a conic inner wall, and the shoulder of the DC motor is crimped to the conic inner wall, and thereby the DC motor is held in the hollow part firmly.

【課題】ステム部材の中に直流モータと振動シャフトが納められた電動歯ブラシの提供を目的とする。
【解決手段】電動歯ブラシは、ステム部材を有し、そこにブラシ部が着脱可能になっている。ステム部材は合成樹脂で構成され、直流モータと、直流モータに連結される振動シャフトを納める中空部を有する。中空部の一端は開かれておりそこから直流モータと振動シャフトが挿入され、中空部の他端は閉じられている。振動シャフトの自由端は中空部の他端において回転可能に保持されている。中空部は円錐形の内壁を有し、直流モータのショルダー部と円錐形の内壁とが圧着することにより、直流モータが中空部内に強固に保持される。
