The flexible member 14 is moved diagonally downward to temporarily extend the flexible member 14 and absorb the impact. At the same time, the vibration isolating rubber 40 is compressed and deformed to reduce the impact, and the spring seats 32 and 3 of the spring 35
3. Suppress abnormal movement (eccentricity, inclination).

As described above, the present invention provides a suspension system using a flexible member in which a coil spring is installed between a spring seat on the rod side connected to the end of the flexible member and a spring seat on the bracket side that slides and guides the rod. Since the rod and the cylindrical anti-vibration rubber are interposed concentrically, the shock acting on the rod is absorbed by the spring, and abnormal behavior of the spring is suppressed by the cylindrical anti-vibration rubber. In addition, since stable tension is always maintained on the flexible member due to the stable operation of the spring, the flexible member will not fall off the pulley due to partial slack, and the ground contact of the wheels as a multi-axle vehicle will be improved. Improved.
