Provided is a solar tracker, using an air spring, of which light-receiving angles can be easily changed by means of a simple structure and of which position can be stably maintained regardless of disturbance and the like due to changes in weather. A solar tracker comprises: a solar cell panel; a frame to which the solar cell panel is fixed; a supporting bar of which one end portion is axially coupled to the frame and the other end portion is fixed to a floor surface, thereby rotatably supporting the frame; a driving bar extending along the floor surface; a linking member connected between the frame and driving bar and for converting the linear motion of the driving bar into the rotational motion of the frame; and an elastic driving unit which is formed by means of a compressible fluid, injected into a body formed from an elastomer, is connected to the driving bar and retracts. |
