The present invention relates to a gravity compensating apparatus applied to a wearable muscular strength assisting apparatus, comprising: a first link extended in the same direction with a first frame of a wearer; a second link which is extended in the same direction with a second frame of the wearer connected with one end of the first frame of the wearer to be rotatable and is connected with one end of the first link to be rotatable; an elastic body of which one end is fixed on the first link and elastic force is changed according to length change between one end and the other end; and a connection unit extended along the longitudinal direction of the first link, of which one end is connected with the other end of the elastic body and the other end is connected with the second link, so as to change the length of the elastic body according to relative rotation of the first link and the second link. The present invention aims to decrease manufacturing cost and weight by substituting an elastic body and a wire for a motor and a decelerator. 본 발명은 착용자의 제1골격와 나란한 방향으로 연장된 제1링크; 착용자의 제1골격의 일단부에 회전 가능하게 연결된 제2골격과 나란한 방향으로 연장되고, 제1링크의 일단부에 회전가능하게 결합된 제2링크; 일단부가 제1링크에 고정되고, 일단부와 타단부 사이의 길이 변화에 따라 탄성력이 가변되는 탄성체; 및 일단부가 탄성체의 타단부와 연결되고, 제1링크의 길이 방향을 따라 연장되며, 타단부가 제2링크에 연결되어 제1링크와 제2링크의 상대 회전에 따라 탄성체의 길이를 가변하는 연결부;를 포함하는 착용식 근력 보조 장치에 적용되는 중력보상장치가 소개된다.
