Purpose; If a steering damper is fixed to a top bridge, as the steering damper is comparatively heavy and the top bridge is on the steering side, steering inertia increases. <??>Accordingly, arrangement structure of the steering damper which does not greatly influence the steering inertia is realized. <??>Construction: A rotatable partition wall 30 is provided in a hydraulic chamber 26 of a steering damper 10 to partition the inside into right hydraulic chamber 27 and left hydraulic chamber 28. A shaft 23 provided at one end of the partition wall 30 is integrally and rotatably coupled to a coaxial steering shaft 14. The both hydraulic chambers 27 and 28 are communicated with each other by a liquid passage 33, and a control valve 31 provided in an intermediate part of the passage is switched to a lock 34 or a throttle 35 thereby a damping force zero status or a damping force generation status is set. The switching is controlled by a control device 32 in correspondence with ON/OFF of a main switch 15. Further, the throttle 35 makes a cross-sectional area of the passage variable, and this control is also made by the control device 32 based on a turning angle speed of the steering shaft 14. A comparatively heavy part such as a main body 17 forming a casing of the steering damper 10 is fixed to a vehicle body front part supporting the steering shaft 14, and the comparatively light-weight partition wall 30, on the steering side. <IMAGE> |
