摘要： An apparatus aiding body balance according to the present invention comprises: a support portion placed on the ground; a foothold portion having one end rotatably coupled to one end of the support portion; and an inclination adjustment portion having one end rotatably provided on the other end of the foothold portion and the other end supported by the support portion, and thus enabling the adjustment of the angle between the foothold portion and the support portion. According to the apparatus aiding body balance according to the present invention, the angle between the foothold portion and the support portion may selectively be adjusted by means of the inclination adjustment portion, and thus the intensity of body balance exercise may be controlled in accordance with the inclination of the foothold portion, enhancing the use efficiency. An anti-slip portion is provided and a stopper protrusion is formed on one side of a foothold frame, and thus the feet may stably be supported without slipping on the inclined foothold portion. The foothold portion, support portion and inclination adjustment portion are provided so as to rotate with respect to each other, and thus the apparatus aiding body balance may be folded into a flat shape, and a plurality of apparatuses aiding body balance may be coupled to each other. Therefore, the apparatus aiding body balance may be stored easily when not in use and exhibits enhanced space utilization.
