Abstract:
A steering device for a two-wheeler, comprising:a frame of a vehicle body; a support member for a front wheel; a steering shaft connecting the support member to the frame so as to be rotatable about an axis thereof; and a rotary steering damper providing a hydraulic resistance force no matter which direction the support member rotates with respect to the frame, the steering damper having: a vane adapted to swing in synchronism with rotation of the support member, oil chambers defined on both sides of the vane and filled with a working fluid, a flow passage allowing the working fluid to flow from one oil chamber to the other oil chamber as the vane swings, the flow passage having a one-way flow passage through which the working fluid always flows in the same direction no matter which direction the working fluid may flow between the oil chambers, and a damping valve arranged in the one-way flow passage, the damping valve having an opening that is varied by an outside signal to vary a damping force generated.
