摘要：
An electric toothbrush includes a stem member on which a replaceable toothbrush is mounted. The stem member is made of synthetic resin and has a cavity for accommodating a DC motor and a vibration shaft connected to the DC motor. One end of the cavity is opened for inserting the DC motor and the vibration shaft together, and the other end thereof is closed. A free end of the vibration shaft is rotatably supported at the closed end of the cavity. The cavity has a cone-shaped wall so that the DC motor is firmly held in the cavity by a rigid contact between a shoulder portion of the DC motor and the cone-shaped wall.
