To provide an improved beauty treatment instrument having multiple functions such as various beauty treatments, skin beautification, and physical therapy.SOLUTION: An outer rotor type motor 100 is rotated by electric control. When the motor rotates, a motor gear disc 110 fixed to a motor drive shaft rotates synchronously. At the same time, since the wave-shaped teeth on the motor gear disc 110 are engaged with the wave surface of a driven disc 210 on a movable bracket set, when the motor gear disc 110 rotates, a tangential force is generated between the gear disc and the driven disc 210 to push down the driven disc 210 along the axial direction. At this time, a front end spring 201 is compressed. In addition, when the gear disc rotates to the valley of the wave, the movable bracket set is raised as a whole by the repulsive force of the spring 201. By repeating such a motion, the movable bracket reciprocates to generate a force of hitting the surface of the human body, thereby relaxing the fascia and muscles of the human body and exerting a massage effect. In addition, a light source 301 realizes a beauty treatment effect.SELECTED DRAWING: Figure 3
