Abstract: The present invention relates to a telescopic single-legged portable working chair using a compression repulsive force of a spring body, wherein: when used, the telescopic single-legged portable working chair is worn on a user′s body such that, when the user sits down, the spring body is compressed by the weight of the user′s body to store power, and when the user stands up, the spring body pushes up the user′s body using the compressed power, so that the power consumption required for the sitting and standing actions of the body can be reduced; when the user repeatedly lifts a weight, the load applied to the user′s joints and muscles is alleviated by the magnitude of a repulsive force of the spring body, so that injuries to the body due to work over a long period of time can be reduced. The compression-repulsive operation of the spring body is controlled by controlling a trigger device linked with a saddle (S1), a saddle spring (S4), a trigger line (T2), a trigger slide (T8), and a trigger arm (T10) after sensing variation of gravity applied to the saddle according to movements of the body preceding the actions for sitting and standing, so that the stability and efficiency can be increased. When sitting, the working chair is balanced while forming a triangle with both legs, and a thrust bearing is mounted on a lower end portion of a frame such that the load is vertically applied, thereby facilitating the direction shifting while sitting.
