Abstract
A steering damper can generate a smaller damping force according to a first damping force characteristic or a larger damping force according to a second damping force characteristic by controlling a flow of hydraulic oil during a steering operation of a steering member. When the associated vehicle is running at a relatively low or medium speed and is not accelerating, and if an operational speed of the steering damper is lower than a predetermined value, damping force according to the first damping force characteristic can be generated in the steering damper. On the other hand, when the operational speed of the steering damper is equal to or higher than the predetermined value, damping force according to the second damping force characteristic can be generated in the steering damper. While the vehicle is running at a high speed or is accelerating, the damping force according to the second damping force characteristic can be generated in the steering damper regardless of the operational speed of the steering damper.
