DYNAMIC DAMPER OF VEHICLE

PURPOSE:To provide a simple structure and cost reduction by installing a balance weight on either side of the front or rear of a vehicle body so that it may move vertically through a parallel link mechanism, and installing a holding spring and a shock absorber. CONSTITUTION:A balance weight 21 is installed on either side of the front or rear of a vehicle body so that it may move vertically through a parallel link mechanism 22. The parallel link mechanism 22 is formed out of a pair of refraction link mechanisms, and one end of their upper and lower links is pivotally connected to the vehicle body or the balance weight 21, and the other end is pivotally connected to each other. There are also provided a holding spring 23 which holds the balance weight 21 so that it may move vertically and a shock absorber 24 which attenuates the vertical action of the balance weight 21. If a vehicle tries pitching or bouncing during running, the balance weight 21 vibrates against the holding spring 23, and the vibration is attenuated by the shock absorber 24 to restrain the vehicle body from pitching and bouncing.
