Abstract
A steering device for a two-wheeler of the present invention includes: a frame; 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 type steering damper providing a hydraulic resistance force in no matter which direction the support member rotates with respect to the frame. The steering damper has 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 working fluid, a flow passage causing working fluid to flow from one oil chamber to the other oil chamber as the vane swings, and a damping valve arranged in a flow passage for the working fluid, and an opening of the damping valve is varied by a signal from outside to thereby generate a damping force optimized according to the travel condition.
