PROBLEM TO BE SOLVED: To provide a dental vibrator capable of giving vibration to bones and the like without cutting the bones and the like at a frequency lower than ultrasonic vibration.SOLUTION: A dental vibrator comprises: a housing 3; a cam 7 receiving a driving force to rotate around a constant axis C in the housing 3; an oscillator 8 brought into contact with the cam 7 and vibrating in the housing 3; a socket 9 formed into such a gimlet shape that the tip thereof is tapered and mounted in the housing 3 so as to be able to freely approach/separate from the oscillator 8; a chip 5 having a base end portion 5a mounted in the socket 9 and a tip portion 5c extending to the outside of the housing 3; and a support part 6 provided in the housing 3, and supporting the chip 5 so that the chip 5 can move between a first position where the socket 9 separates from the oscillator 8 and the oscillation of the oscillator 8 is not transmitted to the chip 5 and a second position where the chip is inclined from the first position, the socket 9 is brought into contact with the oscillator 8 and the oscillation of the oscillator 8 is transmitted to the chip 5.SELECTED DRAWING: Figure 5 |
