Claims (1)

[Scope of utility model registration request] An axle support is attached to the center of the vehicle width direction at the lower part of at least one front and rear side of the vehicle body frame so as to be able to swing left and right around a horizontal axis in the front and rear directions. The central part is attached to the axle support so that it can swing left and right, and between either the left or right side of the axle and the vehicle body frame, a force is applied that pushes one side of the axle downward and causes the axle to always tilt to the left or right. Biasing means for applying the bias is provided;
A running vibration suppression device for a wheeled vehicle, further comprising hydraulic damper means for applying return resistance to the axle when the axle returns to the horizontal state from a tilted state by the urging means.
