Disclosed is an undercarriage having a shock absorption function, including a pair of roller frames (20) facing each other, each roller frame having a plurality of vibration-proof rollers (10) inside thereof, at a lower portion thereof, a main frame (50) disposed between the roller frames and provided with a turn table (70) at a center portion thereof, and a shock absorption bridge (40) for connecting the main frame to the roller frame. According to the present invention, vibration-proof rollers are installed inside a roller frame instead of conventional rollers and the shock absorption bridge is fixed between the main frame and the roller frame, thereby absorbing an external shock in two steps and thus enhancing ride comfort.
