The present invention relates to an apparatus for promoting the growth of height, which comprises: a back supporting plate having a spine relaxing part； a lower supporting frame placed under the back supporting plate, wherein the back supporting plate is coupled to the lower supporting frame to be rotatable； a first motor cylinder connected between the back supporting plate and the lower supporting frame and controlling the rotation angle of the back supporting plate； a foot holding means holding and releasing the feet of a user； and a control part controlling the spine relaxing part and the first motor cylinder. The present invention relates to an apparatus for promoting the growth of height, which alleviates symptoms such as scoliosis, spinal stenosis, pelvic asymmetry, etc. by relaxing the trapezius muscles of the user by vibration to relax spinal discs, enhances the power of concentration by promoting blood circulation, and can promote the growth of height (stature). Furthermore, the apparatus for promoting the growth of height allows the user to quickly and easily hold and release the feet without electrical connection by making an ankle holding structure into an automatic holding and releasing structure using an elastic spring. Furthermore, the apparatus for promoting the growth of height simplifies the structure of the lower supporting frame in comparison with a conventional lower supporting frame structure, thereby saving costs and reducing the volume and weight of the apparatus. In addition, the apparatus is easy to store and carry, is rigid and also can reduce an installation area.본 발명은 척추이완부가 구비된 등지지판과 상기 등지지판의 하부에 위치되어 상기 등지지판이 회동가능하게 결합되는 하부지지프레임과 상기 등지지판 및 상기 하부지지프레임 사이에 결합되어 상기 등지지판의 회동각도를 제어하는 제1모터실린더와 사용자의 발을 홀딩 및 해제시키는 발거치수단 및 상기 척추이완부와 상기 제1모터실린더를 컨트롤하는 제어부를 포함하여 구성된 키 성장 촉진 기구에 관한 것으로서, 사용자의 승모근을 진동에 의해 풀어주어 디스크를 이완시킴으로써 척추 측만증, 척추 협착증 및 골반 비대칭 등의 증상을 호전시킴은 물론, 피의 소통을 원활하게 하여 집중력을 향상시키며, 키(신장)의 성장을 촉진시킬 수 있고, 발목을 홀딩시키는 구조를 탄성스프링을 이용한 자동 홀딩개폐구조로 제
