The present invention relates to a bidirectional vibration device in which vibration is generated by a predetermined rotation angle using a driving wheel, and a detachable diaphragm that vibrates in four directions using vibration. The bidirectional vibration device includes a link having a driving wheel connected to driving means for generating a rotational force and rotating 360 degrees and including an eccentric shaft protruding from the outer circumferential surface, and a hole having an eccentric shaft interposed therebetween. The eccentric shaft reciprocates in accordance with the set trajectory to reciprocate between the top dead center and the bottom dead point of the link and includes an oscillation axis at the other end of the link, . The scrubber is equipped with a separating diaphragm consisting of an external diaphragm and an internal diaphragm in the middle section formed at the end of the vibration axis. The separating diaphragm includes a groove having the same size as the moving distance of the vibration axis on one side of the inner diaphragm. The fixing shaft is mounted on a case accommodating the bidirectional vibration device. The center of the fixing shaft coincides with the center of the groove of the separating diaphragm, The end face of the fixed shaft touches the top dead center and the bottom dead center of the separating diaphragm and the left and right vibrations and the upward and downward movements of the top dead center and the bottom dead center of the internal diaphragm groove are performed by the vibration angle of the vibration axis, Direction vibration occurs. According to the present invention, the skin is massaged or cleaned using the vibration generated in the bidirectional vibration device and the separation type diaphragm for performing the four-direction vibration.본 발명은 구동휠을 이용하여 설정된 소정의 각도를 회동궤적으로 하는 진동이 발생 되는 양방향 진동장치 및 진동을 이용하여 4방향의 진동을 실시하는 분리형 진동판을 구비한 피부 세정기에 관한 것이다. 양방향 진동장치는 회전력을 발생시키는 구동수단에 연결되어 360도 회전하며, 외주면에 돌출된
