The present invention relates to a driving device for a massaging device, and the purpose of the present invention is to prevent vibrations from being generated in a no-load state to prevent a service life from being reduced by vibrations by receiving rotational forces provided through a power providing unit to provide an acupressure force in a load state when a user body is contacted; and to strengthen a product competitiveness by improving assemblability and reducing a manufacturing cost by means of simplification of components. To this end, the present invention, for a driving device for a massaging device which is configured to a massaging device and provides an acupressure force to have a massaging effect, comprises: a main body (10); a rotational shaft (20) which is provided in a center of the main body (10) and rotates according to a rotational power provided through a power providing unit (2); an acceleration rim (30) which is provided coaxially with the rotational shaft (20) on one side of the rotational shaft (20), increases an acceleration force by rotating along with the rotational shaft (20), prevents vibrations from being generated because a rotation is only performed in a no-load state, and induces an acupressure force by means of the acceleration force in a load state; and a pressure housing (40) which is coupled to the acceleration rim (30) not to interfere the rotation of the acceleration rim (30) and, in a load state, provides the acupressure force for a user body by means of the acceleration force induced by the acceleration rim (30).본 발명은 마사지기용 구동장치에 관한 것으로서, 동력제공부를 통해 제공되는 회전력을 전달받아 부하상태 즉, 사용자의 신체가 접촉이 이루어질 경우 지압력을 제공하도록 구성됨으로써, 무부하 상태에서 진동발생을 방지하여 진동에 의한 사용년한이 단축됨을 방지하고 구성요소의 간소화로 조립성 향상 및 제조단가를 낮추도록 하는 제품경쟁력을 강화하는 데 그 목적이 있다.이를 위해 본 발명은, 마사지기에 구성되어 지압력을 제공함에 따라 마사지효과를 가지도록 하는 마사지기용 구동장치에 있어서, 본체(10)와; 상기 본체(10)의 중앙에 구성되어 동력제공부(2)를 통해 제공되는 회전동력에 따라 회전하는 회전축(20)과; 상기 회전축(20)의 일측에 상기 회전축(20)과 동심원상태로 구성되어 상기 회전축(20)과 함께 회전하면서 가속력을 증강시켜, 무부하 상태
