PURPOSE: A height growth promoting device is provide to reduce a concern of injury by not overstraining the knee with minutely adjusting the tensile force which elongates the leg according to the different individual condition of the knee； and use conveniently by moving the height growth promoting device to a desired place since the device is very simple and portable. CONSTITUTION: A height growth promoting device (10) comprises: a harness (12), an elongating device (16)； and a holder (28). The harness is worn in the hips of the user, and provides a latching member (14) to both side parts of the user as the state in which the harness is worn in the hips. The elongating device comprises: a main body part (18) which covers the outer side of a leg of the user and has an inner space, and which is extended to a longitudinal direction while the top end portion is attachably and detachably inserted in the latching member； a traction unit (20) which is extended to the longitudinal direction by moving with sliding to the longitudinal direction of the main body part with being inserted into the inner space of the main body part； an adjusting means which determines a taking out distance of the traction unit about the main body part while being installed in the main body part； a stopper portion which fixes the traction unit in which the taking out distance is determined with the adjusting means as the state of determining the taking out distance. The holder fixes the part which is below the calf of the leg of the user to the traction unit while being mounted on the traction unit.본 발명은 키 성장 촉진기구에 관한 것이다. 이는 사용자의 엉덩이에 착용되는 것으로서, 엉덩이에 착용된 상태로 엉덩이의 양측부에 해당하는 지점에 걸림부재를 제공하는 하네스와； 상기 걸림부재에 그 상단부가 착탈 가능하게 끼워지며 길이방향으로 연장되고 내부공간을 제공하며 사용자의 다리 외측면을 커버하는 본체부와, 상기 본체부의 내부공간에 그 일부가 삽입된 상태로 본체부의 길이방향으로 슬라이딩 운동하며 길이방향으로 연장된 견인부와, 상기 본체부에 설치되어 본체부에 대한 견인부의 인출거리를 결정하는 조절수단과, 상기 조절수단에 의해 인출정도가 결정된 견인부를 그 상태로 고정시키는 스토퍼부를 구비한 인장기와； 상기 견인부에 장착되며 사용자의 종아리 이하의 부위를 견인부에 고정시키는 홀더를 포함하는 것을 특징으로 한다.상기와
