摘要 |
An electric toothbrush includes a drive part, a driver, a brush part and a vibration-absorber. The drive part includes a drive shaft provided to be lineally movable and a brush part detachably attached to one end of the drive shaft. The driver is configured to apply reciprocal force to the drive shaft to reciprocally lineally move the drive shaft. The vibration-absorber is connected to the drive shaft via a second spring to be lineally movable along the drive shaft. A weight ratio of a weight of the vibration-absorber to a weight of the drive part is at least 0.9 and at most 1.1.
