<p>PURPOSE:To secure sufficient vibration of brush hair and to increase a dental deposit eliminating effect at the time of brushing by providing a brush part, a grip part, and a vibration generating part, connecting the vibration generating part to the grip part through a vibration transfer suppressing means, and vibrating the brush part by the vibration generating part. CONSTITUTION:In a grip part, a battery 12 is contained and in a vibration generating part 14, a motor 16 is contained, and to a rotation axis 18 of the motor 16, a weight 20 is fixed eccentrically. The vibration generating part 14 is connected to the grip part 10 through a spring 22. When a switch 24 is turned on, a power source is supplied to the motor 16, the weight 20 rotates in the periphery of an eccentric axis, and the whole vibration generating part 14 vibrates. The vibration is transferred directly to a brush part 28, and the brush part 28 is vibrated. Since the grip part 10 is connected to the vibration generating part 14 through the spring 22, the vibration of the vibration generating part 14 is absorbed by the spring 22, the transfer of vibration to the grip part 10 is suppressed, an object to be vibrated becomes only the brush part 28, and the brush part secures sufficient vibration.</p> |
